How Hard Is The
Sergeant Exam Really?
An Honest Psychologically Grounded Breakdown of NPPF Step 2
Direct Answer
The Police Sergeant Exam is difficult because it tests detailed legal knowledge under time pressure. Most candidates underestimate the volume of criminal law, PACE and misconduct regulations required.
With structured preparation it is passable, but without disciplined revision it has a high failure rate because it rewards technical precision over operational familiarity.
Executive Summary
The Sergeant Exam is not an IQ test; it is a preparation test. It rewards a very specific type of intellectual discipline.
Section 1:
The Difficulty Drivers
Volume of Law
The technical shock of the Sergeant exam is the sheer number of offence elements you must hold in active memory. You aren't just tested on 'Theft'; you are tested on the subtle wording differences between Appropriation, Property, and Dishonesty thresholds.
Time Pressure
With roughly 3 hours for 150 questions, you have approximately one minute per decision. This does not allow for "deep thinking". The exam rewards recognition speed. If you have to think about what Code G necessity means, you have already lost the time buffer needed for the complex fraud scenarios at the end of the paper.
The False Confidence Trap
"I've been in 10 years, I know the law." This is the most common reason for failure. Operational familiarity often hinders legal precision. Knowing how to do a stop-search on the street is completely different from knowing the exact statutory phrasing of Section 1 PACE prohibited articles.
Section 2:
The Pass Rate Reality
Pass rates vary significantly by force and by year, but they typically sit within the 40% to 65% range. This means that in any given sitting, roughly half of the candidates will fail.
First-time passes are significantly lower than retakes.
The exam is designed to differentiate, not to guarantee rank entry.
Section 3:
Common Failure Points
Sexual Offences
Consent definitions and specific 'intent' thresholds in the 2003 Act.
PACE NECESSITY
Failing to distinguish between the 'grounds' for arrest and the 'necessity'.
Misconduct Regs
Neglecting the 2020 Conduct Regulations which are heavily weighted in the syllabus.
BURGLARY NUANCE
The difference between 9(1)(a) and 9(1)(b) intent points.
ATTEMPT VS PREP
Technical 'more than merely preparatory' tests in criminal law.
POLICE REGS
Underestimating the complexity of overtime, rest days, and leave rules.
Section 4:
Revision Reality
Success is almost entirely determined by the Preparation Window. "Cramming" rarely works for the Sergeant exam because of the depth of recall required.
