Routes

The NIE on Direct
Entry Detective Routes

If you joined as a trainee detective through detective DHEP, Police Now or a force's own detective entry programme, the National Investigators' Exam arrives early, often while you are still learning the basics of the job. This guide sets out when each route schedules it, using Police Now's and forces' own pages, how the College's PIP policy lets entry-route students sit it before PIP1 is complete, what study support trainees actually get, and what a fail means, verified where we could and marked where we could not.

Short answer: when do direct entry detectives sit the NIE?

Earlier than most constables moving into CID. Police Now says the NIE is a key part of its 13-week residential academy. On detective DHEP it depends on the force: Staffordshire University's partners list it in year 1, while Avon and Somerset and the Met's DC entry programme put it in year 2. It is the same exam with the same pass mark. You must pass before PIP2 sign-off and the substantive detective title, and resits are subject to force policy.

The NIE on direct entry routes at a glance

Written from the College of Policing's PIP programme policy 2023 and NIE candidate handbook 2026, Police Now's own pages, and force and university pages read on 11 October 2026. Some force pages blocked our reader, so we used web archive copies and say so. Routes change between intakes: your joining instructions and your force are the final word.

The key facts
Question	Answer
Is the NIE compulsory?	Yes: you must pass before PIP2 sign-off and the substantive detective title
Same exam as everyone else?	Yes: 80 questions, 2 hours, pass mark 39 of 70, four national sittings a year
When on Police Now?	Police Now says it is a key part of its 13-week residential academy
When on detective DHEP?	Varies: year 1 (Staffordshire University partners) to year 2 (Avon and Somerset, Met DC entry)
Before PIP1 is complete?	Allowed on entry routes, according to the PIP policy
Study support	At force discretion: study time, books, courses vary widely
After a pass	PIP2 programme, tutor, portfolio and sign-off; pass valid three years less one day
After a fail	Resit subject to force policy; development plan; some forces limit resits
Employment consequences of a final fail	Not verified for any force

Each route and when it schedules the NIE

The College does not publish one national timetable for direct entry detectives. The PIP policy lets forces schedule the NIE "at a time appropriate to the programme timetable". These are the timings we could verify on each organisation's own pages:

When the NIE falls on detective entry routes
Route	Run by	Length	When the NIE is sat	Source
Police Now National Graduate Programme (detective)	Police Now with partner forces	2 years	During or just after the 13-week academy	Police Now news, June 2026; programme page
Detective constable DHEP, Staffordshire, Warwickshire, West Mercia	Forces with Staffordshire University	2 years	Year 1 (listed as a year 1 module)	Staffordshire University course page
Detective DHEP (DDHEP), Avon and Somerset	Force with UWE Bristol	2 years	Year 2	Force page
DC entry programme, Metropolitan Police	Met	4 years	Year 2, after a uniform first year	Met page, archived October 2025
DHEP Detective, Humberside	Force with York St John University	2.5 years	After 12 months in uniform, in the investigation unit	Force page, archived October 2025
Detective constable programme, Derbyshire (A level entry)	Force	2 years	After about 12 months' service	Force careers page
Detective DHEP, Thames Valley	Force	2 years	Not stated; studied in own time	Force FAQ, archived (text possibly 2022)

The pattern: academy-led routes (Police Now) put the NIE right at the start, some university partnerships put it in year 1 alongside the diploma, and routes that begin with a full uniform year put it in year 2. Whatever your route, the exam itself is identical and is sat on one of the four national dates.

Find your own sitting

Ask your detective training team which sitting your cohort is entered for and who registers you. The handbook says candidates register on AIMS through their force's NIE liaison contact, and forces may set earlier deadlines than the College's. The next sitting is Tuesday, 17 November 2026; registration closes at 6pm on Wednesday, 21 October 2026.

Direct entry vs moving from PC to DC

Most NIE candidates are constables selected by their force to move into CID. Direct entry trainees meet the same exam from a different starting point:

Two ways to the NIE
	Direct entry trainee detective	Constable moving to CID
When the NIE is sat	Set by the programme: academy, year 1 or year 2	When the force selects you for PIP2 and enters you
PIP1 first?	Not necessarily: the PIP policy allows the NIE before PIP1 is complete on entry routes	Yes: the handbook requires current PIP1 competence, evidenced by the force
Operational experience at the time	Weeks to about a year	Usually years of volume crime
Study pattern	Often taught or timetabled within the programme, alongside a diploma	Self-study around shifts
Resits	Subject to force policy; some detective programmes allow one	Subject to force policy
If you never pass	No PIP2 accreditation; programme consequences set by the force (not verified)	No PIP2 accreditation; you stay in or return to your current role
The exam itself	Identical	Identical

The biggest practical difference is experience. A constable with years of volume crime can picture a PACE Code C detention review or a CPIA disclosure decision; a trainee a few weeks in often cannot. That is why scenario-based practice matters more on direct entry routes.

PIP1 to PIP2 on an entry route

For most investigators the order is fixed: PIP1 competence, then the NIE, then PIP2. The handbook says all NIE candidates must be able to demonstrate current investigative competency against PIP1. The PIP policy makes an exception for entry routes:

PIP programme policy 2023

"Where a student is undertaking a PEQF entry route, it may not be possible to complete PIP 1 before sitting the NIE. In these cases, forces should support students to complete the NIE at a time suitable to the programme being undertaken. Students must pass the NIE before completing the PIP 2 programme."

The policy's Annex B sets out how investigation learning is built into the initial entry routes (it dates from 2023; check your own programme):

PIP within the entry routes (PIP policy 2023, Annex B)
Route	Probation	Programme years	PIP2 accreditation
PCDA (degree apprenticeship)	3-year probation	PIP1 learning and portfolio in years 1 to 2; NIE as the gateway to PIP2, separate from the degree	PIP2 learning in year 3; PIP2 workplace assessment after qualifying (portfolio can start in year 3)
DHEP and Police Now	2-year probation	Two-year programme covering the PC syllabus, including PIP1 and PIP2 learning on the PIP career path	PIP2 workplace assessment after qualifying (portfolio can start in year 2)
Post-degree programme (pre-join degree)	2-year probation	Practical PC syllabus including PIP1 and PIP2 learning	PIP2 workplace assessment after qualifying (portfolio can start in year 2)
Non-academic standalone (staff, PC to DC)	Not applicable	One to two years of learning	Work-based assessment for PIP1 or PIP2

Two consequences. First, on an entry route you may sit the NIE while still building PIP1 competence on the job, so the exam can feel further ahead of your experience than it does for a constable who has investigated volume crime for years. Second, PIP2 accreditation itself usually comes after you qualify from the programme, through a workplace assessment, so passing the NIE is the start of the detective part of your training, not the end. More on the levels in PIP1 vs PIP2 explained.

Police Now: the NIE in the academy

Police Now is a charity that runs a two-year National Graduate Programme with partner forces, with a detective specialism. Its pages, read on 11 October 2026, say:

The detective academy is a 13-week intensive programme covering investigative techniques, law, interview skills and evidence gathering; its FAQ says detective participants live on site for twelve weeks.
Its 26 June 2026 news release says "A key part of the academy is sitting the NIE".
Its detective programme page lists the steps as academy, force integration, then the NIE, and says programme details may evolve from cohort to cohort.
A participant's "day in the life" during the academy ends with NIE revision consolidating that day's lessons.
Entry needs a 2:2 degree or above; participants complete a level 6 or level 7 policing qualification depending on the programme.

So on Police Now the NIE comes within weeks of joining, taught alongside the rest of the academy, with a cohort sitting together. The College's September 2026 results overview lists Police Now as a nominating organisation, with its candidate numbers suppressed because they were small.

Police Now's pass rate claims

Police Now's June 2026 release says 86.3% of its trainee detectives passed against a national rate it gives as 67%, and four percent achieved the exceptional grade. Its detective page claims a 75% first-time pass rate against 60% nationally. These are Police Now's own figures for its own cohorts; we could not check the 67% against a College overview for that sitting. The College's published national rate for September 2026 was 63.3%.

Police Now and detective DHEP compared, for the NIE

Timing Police Now: within the first months, as part of or right after a 13-week academy. Detective DHEP: anywhere from year 1 to year 2, depending on the force and university.

How it is taught Police Now: a residential academy with law and investigation teaching and NIE revision built into the day. Detective DHEP: varies, from a timetabled diploma module to self-study in your own time.

Who you sit with Police Now: a national cohort from several forces. Detective DHEP: your own force or regional intake.

What stays the same The exam, the pass mark, the rules, the resit framework in the handbook, and the PIP policy's requirement to pass before PIP2 sign-off. Force policy still decides resits for both.

Detective DHEP: what forces and universities say

The degree holder entry programme is the national graduate route that forces run with a university. Some forces run a detective version. See DHEP explained for the route itself. On the NIE:

Staffordshire University (Staffordshire, Warwickshire and West Mercia). The detective constable DHEP lists "National Investigators Examination (NIE)" among the year 1 modules, alongside introduction to operational policing, evidence based practice and the independent patrol status portfolio, and says you must complete and pass the NIE.
Avon and Somerset (with UWE Bristol). "The National Investigators' Exam (NIE) is a requirement during year two of study."
Humberside (with York St John University). The archived page described two and a half years: the first 12 months as a uniformed constable on patrol, then 18 months in an investigation unit studying for the NIE and completing the diploma and detective portfolio, with 20 per cent off-the-job time.
Thames Valley Police. The archived FAQ said detective DHEP students must complete everything in the PC DHEP plus the NIE, PIP2 interview training, the PIP2 investigator development programme and a PIP2 portfolio, and study for the NIE in their own time.
Bedfordshire (with Anglia Ruskin University). The university's page says you will be required to sit the NIE and become a trainee detective constable after your first year; it does not give the NIE's timing.

For what the route involves day to day, and the risks of joining straight into CID, see direct entry detective explained.

Other detective entry routes

Force detective programmes without a degree. Derbyshire's detective constable programme is open with two A levels or equivalent. Trainees start on the police constable entry programme, work response, then become trainee detectives and sit the NIE "after 12 months' service".
The Met's DC entry programme. Needs a degree; four years in total; a uniform first year mirroring the PC entry pathway; the NIE during year two; accredited detective constable at the end (archived October 2025).
PCDA. The PIP policy's 2023 Annex B describes the NIE as the gateway to PIP2 on the degree apprenticeship, separate from the degree assessment. Check whether your force still recruits on this route.
Police staff investigators. Staff joining a PIP2 role must complete PIP1, the NIE and PIP2 learning, and staff who do not pass cannot progress to PIP2 or above. See civilian investigator explained.
Direct entry to detective inspector level. The PIP policy's direct entry route to PIP2 investigative manager also includes passing the NIE. See direct entry inspector explained.

Why your NIE timing matters

Sitting early (academy or year 1) The law is fresh from training and you are studying full time or close to it. The trade-off is less operational context: questions test application, and you may not yet have dealt with the situations they describe. You also study alongside diploma assessments.

Sitting later (year 2) More experience to anchor the law, but you study around shifts and casework, often with less structured teaching. The handbook recommends at least 14 weeks of independent study; on a busy investigation team that needs protecting.

The national calendar There are four sittings a year, so a programme that slips by a few weeks can push you to the next sitting three months later. Registration closes about four weeks before each exam, so your force registers you well ahead.

Validity and the portfolio A pass lasts three years less one day. Annex B places PIP2 accreditation after qualification, so an early pass still has to see you through to sign-off. Validity cannot be extended for operational reasons or lack of opportunities.

Registration on an entry route

On a programme, the force usually tells you which sitting you are entered for. The handbook rules on registering still apply to you personally:

Registering for the NIE
Point	What to do	Source
Who registers you	You register on AIMS with the link from your force's NIE liaison contact; the force verifies and allocates you	Handbook: applications
Your details	Name, date of birth, national insurance number and email must be exact: you need them to open your result	Handbook: applications
Deadlines	The College's closes at 6pm about four weeks before the exam; your force may close earlier	Handbook: registration periods
Reasonable adjustments	Tell your liaison contact at registration; reports due by the registration closing date	Handbook: adjustments
Off sick or on limited duties	You need a force medical examiner's certificate of fitness at registration	Handbook: sickness
Withdrawing	Tell your liaison contact at once; forces are charged for anyone registered two weeks before	Handbook: withdrawals

Dates if your cohort sits in 2026

Whichever route you are on, your cohort sits on one of the four national dates. If yours is entered for one of these, the dates that matter are:

2026 NIE sittings for a cohort
Sitting	Registration window (closes 6pm)	Exam day	Results by	Pass valid until

The College had not published 2027 dates when we checked on 11 October 2026. Full details, including what we know about 2027, are on NIE exam dates 2026.

Study support trainees get

The PIP policy says NIE success "will be improved by support to candidates" and leaves the form to forces. What forces and Police Now publish:

Published study support
Type	Examples
Protected study time	Derbyshire: an extra 56 hours off towards the end of the first year. Thames Valley (archived): two days' paid study leave if matched with two days' annual leave. Humberside: 20 per cent off-the-job time for the whole programme
Teaching in the programme	Police Now: law and investigation in the 13-week academy, with NIE revision in the academy day. Universities: the NIE sits inside the diploma timetable on some routes
Books and courses	Thames Valley (archived): revision books, a two-day crammer and an e-learning package from an external provider, plus an in-force study day
College resources	Knowledge Hub candidate group: a small sample of College practice questions, revision timetables, study group guidance; 30% off the Manuals through College Learn
National policy	PIP policy: support at forces' discretion, for example reference books, protected study time or crammer courses

If your joining instructions do not mention NIE study time, ask. It is easier to agree protected time at the start of the programme than to find it in the month before the exam.

Studying for the NIE around a training programme

The syllabus is the Blackstone's Police Investigators' Manual, parts 1 to 4, and the handbook says questions come only from the current edition. On an entry route you have two extra pressures: diploma work and very little operational experience. What helps:

Map the Manual to your programme. Note which parts your training covers and when. Revise each part soon after it is taught, while it is fresh.
Weight your time to the paper. Part 1 (powers and procedures, including the PACE Codes) carries the most scored questions in the College's published breakdown. See the NIE syllabus.
Practise application, not recall. The handbook says the exam does not test pure factual recall or tables, so turn each topic into scenario questions.
Use your cohort. Academy and university cohorts make study groups easy; the College's Knowledge Hub has guidance on running one.
Build a dated plan. The NIE revision plan has 4, 8 and 12 week timetables, and the free revision timetable builds one to your sitting date.
Test under exam conditions. Start with the free NIE mini mock. For full timed papers, our NIE exam prep toolkit (our own paid product) has 80-question mocks weighted like the College's breakdown, with original questions, not real exam content.

A study rhythm that fits a training programme
When	What to do	Why
Before the programme starts	Read the handbook's syllabus list for parts 1 to 4; get the right Manual edition	Do not try to learn the Manual before you are taught the basics
As each topic is taught	Read the matching Manual chapter within a few days; write ten of your own scenario questions	Keeps revision in step with training
Every week	Two or three short sessions of mixed practice questions on what you have covered	Spaced practice beats one long session
About 8 weeks out	First timed mixed mock; list weak chapters by part	Set the plan for the last stretch
About 6 to 2 weeks out	Close gaps, weighted by how many questions each part carries; one full timed paper a week	Part 1 carries the most
Final week	Familiarisation exercise, device check, light review of PACE Code points	No new chapters

The method in detail is in how to pass the NIE, and the exam-day rules, including the ban on AI and on sharing topic areas with your cohort afterwards, are in NIE exam day rules.

Cohort chat after the exam

Cohorts often sit the same sitting at different times of day. The handbook lists discussing questions or topic areas with anyone, including on social media, as a breach, with removal of the result, a ban of two years or more and a professional standards referral. Keep the group chat to how it felt, not what came up.

National pass rates for context

The College does not publish pass rates by entry route. The national figures from its results overviews, for the six most recent sittings we hold:

National NIE results (College results overviews)
Sitting	Sat	Passed	Pass rate
September 2026	1,050	665	63.3%
March 2026	1,633	1,040	63.7%
November 2025	1,294	672	51.9%
September 2025	1,318	792	60.1%
June 2025	1,500	822	54.8%
March 2025	1,612	941	58.4%

Force rows in the overviews mix every kind of candidate, so a force's rate tells you little about its direct entry trainees. The College warns against comparing forces with small numbers. Every sitting is in NIE pass rates.

After you pass

From NIE pass to substantive detective
Step	On an entry route
Posted to a trainee PIP2 role	Often already in one on a detective route; the NPCC chart notes some forces post before the pass
PIP2 investigator course	The classroom component; on entry routes it may be part of the programme
Tutor and monthly reviews	Trainee, tutor and supervisor meet monthly during the workplace assessment
Portfolio	Evidence against the PIP2 investigator assessment criteria; Annex B says DHEP and Police Now students can start it in year 2
Sign-off	Accredited PIP2 investigator; substantive detective title
Annual CPD	Needed to keep accreditation; otherwise PIP inactive

The PIP policy expects most people to complete PIP2 within six to twelve months of passing; on an entry route the programme timetable usually governs instead, with Annex B placing the PIP2 workplace assessment after qualification. Keep your feedback report: the College will not reissue it. More in NIE results day.

If you fail: what we could verify

This is the question trainees ask most and the one with the least published detail. What we could verify:

You can usually resit. The handbook gives unsuccessful candidates the opportunity to resit at the next sitting, subject to force or organisation policy. After a second fail a development meeting is compulsory.
No pass, no PIP2. The PIP policy: students "must successfully pass the NIE before being signed off as a PIP 2 investigator". Individuals who fail "should be provided with a development plan and relevant support. If an individual is unable to meet these requirements, they will not be accredited at PIP 2 and should be removed from a PIP 2 role."
Some forces allow one resit. Thames Valley Police's archived detective DHEP FAQ: "If I don't pass my NIE detective exam can I still qualify as a detective? No, however you will be given one opportunity to re-sit the exam."
Switching routes is a force decision. Humberside's archived page said detective DHEP candidates could not transfer to the uniform DHEP once started. Derbyshire says it will discuss staying in service as a uniformed constable if the detective programme is not for you.
Forces are told to plan for it. The PIP policy suggests forces consider, for external candidates, whether the exam should be a condition of recruitment or probation. We found no force publishing such a condition.

Not verified

We could not verify, for any force or for Police Now, what happens to a trainee's employment, probation or programme place after a final NIE fail. If it applies to you, get your force's written policy and speak to your Federation representative before any meeting. The full resit rules are in what happens if you fail the NIE.

Pay and the detective title

Passing the NIE does not change your pay. Constables are paid by pay point, not by whether they are on a detective route; Thames Valley Police's archived FAQ said there was no pay difference between its PC and detective DHEP routes. The title of substantive detective comes only with PIP2 sign-off. For pay by rank, including detective sergeant and above, see detective ranks and salaries.

Mistakes trainee detectives make with the NIE

Drawn from the handbook's own rules and warnings, not from candidate anecdotes:

Avoidable mistakes
Mistake	Why it matters
Revising from an older Manual handed down by a tutor or colleague	The handbook says questions come only from the current edition and advises against previous editions
Relying on academy or university notes instead of the Manual	Training notes are a summary; the Manual is the syllabus
Leaving the NIE until diploma deadlines are done	The two often fall in the same months; plan both from the start
Only doing untimed topic quizzes	The real paper allows about 90 seconds a question
Skipping PACE Code detail	The handbook says Code provisions the Manual refers to are examinable
Mistyping details in AIMS	You need your exact email, date of birth and national insurance number to open your result
Talking about the paper in the cohort chat	Sharing or discussing topic areas is a rule breach with serious penalties

Most of these come from the pace of a training programme: there is always something more urgent than the NIE until it is close. A dated plan agreed with your tutor at the start is the simplest protection.

Worked scenarios

Illustrative examples built from the sources above, not real cases.

1. The academy sitting A Police Now participant sits the NIE during the academy, ten weeks after starting. They have never interviewed a suspect, so they turn every PACE Code C topic into a short scenario and practise at 90 seconds a question. They pass, and start in force as a trainee investigator.

2. Year 1 alongside the diploma A detective DHEP student whose programme lists the NIE in year 1 has a diploma assignment due the same month. They agree a plan with their tutor: assignment first, then six focused weeks on parts 1 and 2 of the Manual.

3. Year 2 on a busy team A trainee on a route with a uniform first year moves to an investigation unit and sits the NIE in year two. Casework eats study time. They ask for protected study hours, which their force's policy leaves to local discretion, and book them in their rota.

4. A fail with one resit allowed A trainee in a force allowing one resit fails by three marks. They register for the next sitting at once, ask in writing what happens to their role if the resit fails, and use the feedback report to target two parts.

5. The early pass and the long portfolio A trainee passes on Tuesday, 17 November 2026. Their pass lasts until Friday, 16 November 2029. Their PIP2 workplace assessment runs after they qualify. They diarise the expiry date so the portfolio is signed off comfortably before it.

6. The cohort group chat A cohort sits on the same day at different times. One member, finishing first, posts which areas were heavy. That is sharing topic areas, a breach that can cost the sender their result and lead to a professional standards referral.

Common myths

"Direct entry trainees sit an easier version."It is the same national exam, dates, pass mark and rules.

"Everyone on DHEP sits it in year 2."Timing varies by force and university: some list it in year 1.

"Passing the NIE makes you a detective."The substantive title comes with PIP2 sign-off after the portfolio.

"You need PIP1 before you can sit it."Not on entry routes: the PIP policy lets forces schedule it before PIP1 is complete.

"Fail it once and you are out."Resits are usually available, subject to force policy, though some forces allow only one.

"Detectives earn more as constables."Pay is by rank and pay point, not detective status.

Questions to ask your force or programme

Which NIE sitting is my cohort entered for, and who registers me?
Which edition of the Blackstone's Investigators' Manual will that sitting use, and is it provided?
How much protected study time do I get, and when?
Is the NIE taught in the programme, or is it self-study?
How many resits does force policy allow on my route?
What happens to my role, probation and programme place if I do not pass within the attempts allowed?
Can I move to a uniform route, and on what terms?
When will I start the PIP2 portfolio, and who is my tutor?

Checklist for direct entry trainees

Know your sitting date and your force's internal registration deadline.
Registered on AIMS with exact details; confirmation screenshot saved.
Correct Manual edition for your sitting in hand.
Protected study time agreed and in the rota.
A dated plan that follows your programme's teaching order.
Timed practice at 90 seconds a question started at least six weeks out.
Your force's resit policy, and what happens if you reach its limit, confirmed in writing.
Familiarisation exercise and device check done in exam week.
After the exam: nothing about questions or topic areas in the cohort chat.

What we could not verify

Employment consequences of a final fail on any direct entry route, including Police Now. None of the pages we read publishes them.
The exact week Police Now cohorts sit. Police Now's own pages place the NIE in the academy (June 2026 news) and after force integration (programme page), and say details evolve.
Police Now's pass rate claims. They are Police Now's figures; the College suppresses Police Now's counts in its overviews, and we did not see a College overview for the June 2026 sitting.
Current versions of three force pages. The Met, Humberside and Thames Valley pages were read as web archive copies (October 2025 and June 2026); Thames Valley's text may date from 2022.
Timing on routes we did not check. We read a small number of the forces that run detective entry; others may differ.

Quick answers

Frequently Asked Questions

Do direct entry detectives have to pass the NIE?

Yes. The College of Policing's PIP programme policy 2023 says the NIE is a prerequisite for the PIP 2 investigator programme and that students on entry routes must pass it before being signed off as a PIP 2 investigator. Only those signed off may use the title of substantive detective.

When do you sit the NIE on detective DHEP?

It depends on the force and its university partner. Staffordshire University lists the NIE as a year 1 module on its detective constable DHEP (with Staffordshire, Warwickshire and West Mercia). Avon and Somerset says the NIE is a requirement during year two. Humberside's page described studying for it in the investigation unit after a first uniform year. Ask your force for your cohort's sitting.

When do Police Now detectives sit the NIE?

Early. Police Now's news release of 26 June 2026 says sitting the NIE is a key part of its 13-week residential academy. Its programme page lists the NIE as a step after joining your force, and says details evolve between cohorts. Either way it comes well inside the first year of the two-year programme.

Can you sit the NIE before finishing PIP1?

On an entry route, yes. The PIP policy says that where a student is on a PEQF entry route it may not be possible to complete PIP1 before the NIE, and forces should support students to sit it at a time suited to the programme. Other candidates must normally show PIP1 competence first.

What happens if a trainee detective fails the NIE?

Nationally, they can usually resit at the next sitting subject to force policy, and the PIP policy says they should get a development plan and support. If they cannot meet the requirements they will not be accredited at PIP2 and should be removed from a PIP2 role. Force rules vary: Thames Valley Police's archived detective DHEP FAQ allowed one resit. We could not verify any force's employment consequences.

Do Police Now trainees have a higher NIE pass rate?

Police Now says so: its 26 June 2026 release reports 86.3% of its trainee detectives passing against a national rate it gives as 67%. That is Police Now's own figure; the College's results overviews list Police Now as a nominating organisation but suppress its counts. Nationally, 63.3% of candidates passed in September 2026.

Do I get study leave for the NIE on DHEP?

It is up to your force. The PIP policy says support is at forces' discretion, giving reference books, protected study time and crammer courses as examples. Derbyshire publishes 56 hours of study time before its detective trainees' NIE; Thames Valley Police's archived FAQ described two days of paid study leave if matched with two days of annual leave.

How long is my NIE pass valid on a direct entry route?

Three years less one day from the date you sat it, the same as for anyone. A pass on Tuesday, 17 November 2026 would last until Friday, 16 November 2029. The PIP policy says validity cannot be extended for operational reasons or lack of opportunities, so your PIP2 portfolio must be finished inside it.

Am I a detective once I pass the NIE?

Not yet. You are a trainee investigator. The PIP policy says only those who complete the PIP2 portfolio and are signed off as accredited PIP2 investigators can use the title of substantive detective. On most direct entry routes that comes towards or after the end of the programme.

Is the NIE different for direct entry trainees?

No. It is the same 80-question, 2-hour online exam on the same dates, with the same pass mark of 39 out of 70 (55.7%) and the same rules. What differs is when your programme schedules it and how much study support your force gives.

Can I switch to a uniform route if I fail the NIE?

It depends on the force. Humberside's detective DHEP page (archived October 2025) said candidates could not transfer from the detective DHEP to the uniform DHEP once started. Derbyshire says that if its detective programme is not for you it will discuss staying in service as a uniformed constable. Ask your force for its written policy.

Do detective constables earn more than uniformed constables?

Constable pay is set by rank and pay point, not by whether you are a detective; Thames Valley Police's archived FAQ said there was no difference in pay between its PC and detective DHEP routes. Allowances can differ by role and force. See our detective ranks and salaries guide for the scales.

Who registers me for the NIE on a training programme?

You register yourself on AIMS using the link your force's NIE liaison contact sends, and the force verifies and allocates you to a sitting. On a programme the force usually tells you which sitting your cohort is entered for. Enter your details exactly, because you need them to open your result.

Which Blackstone's Manual do direct entry trainees need?

The same as everyone: the edition named in the handbook for your sitting. The 2026 handbook says 2026 sittings examine the law only as it appears in the 2026 Blackstone's Police Investigators' Manual. Ask whether your programme provides it; the College says officers and staff in England and Wales can get 30% off through College Learn.
