Promotion & Career Progression
Master the NPPF promotion process, assess yourself against the CVF, prepare for interviews, and understand success rates across ranks and forces.
Unofficial independent resource — always verify with official sources (College of Policing, your force, PFEW).
NPPF Promotion Process
The National Police Promotion Framework replaced OSPRE in 2020. Here is a breakdown of each step.
NPPF vs SIPP — Where Things Stand in 2026
- • Legal exam (Step 1) + Work-based assessment
- • Structured interview + Senior assessment
- • Used by majority of E&W forces
- • 2026 exam dates: Sgt March/October, Insp May/November
- • Structured Interview + Presentation format
- • Pilots: Gwent, Lincolnshire, Leicestershire, Avon & Somerset + others
- • Formal evaluation April 2026, possible national rollout 2027
- • Check with your force for current process
Scotland & PSNI: Police Scotland uses its own Competency-Based promotion process (not NPPF). PSNI operates a separate Assessment Centre model. The information below covers England & Wales.
A multiple-choice legal knowledge examination testing your understanding of criminal law, evidence and procedure, and general police duties. This replaced the old OSPRE Part 1 exam.
What It Covers
The exam covers Crime (Theft Act, Criminal Damage, Sexual Offences, Fraud), Evidence & Procedure (PACE, disclosure, interviewing), General Police Duties (road policing, public order, terrorism legislation), and for Inspector candidates, supervisory management principles.
Format
150 multiple-choice questions in a 3-hour exam. Questions are scenario-based, testing application of law rather than rote memorisation. Pass mark varies but is typically around 55-60%.
Preparation Tips
Use Blackstone's Police Manuals (the official study material). Join a study group — many forces organise these. Complete as many practice papers as possible. Focus on understanding principles, not just memorising sections. Allocate 3-6 months of serious study time.

- • Police Promotion Advice (PPA) — online MCQ platform with timed practice exams
- • Force study groups — ask your tutor constable or Federation rep about access
6-Month Study Plan
Read Blackstone's Crime volume. Complete end-of-chapter questions. Aim for 80% on practice papers before moving on.
This is the most heavily tested area. Learn PACE codes systematically. Practice applying codes to scenarios.
Broader but shallower than the first two areas. Focus on commonly tested topics — RTA powers, drugs search powers, public order offences.
Do at least 3 full 150-question mocks under exam conditions. Analyse wrong answers — understand why, not just what.
Do not re-read everything. Identify your 10 weakest topics from mock analysis and focus all revision there. Rest the week before.
5 Sample Questions with Explanations
Exam Day Strategy
Timing
150 questions in 180 minutes = 72 seconds per question. If you spend more than 90 seconds on any question, mark it and move on. Return at the end.
Elimination Technique
On difficult questions, eliminate the two most obviously wrong answers first. Your chance of getting it right improves from 25% to 50%. Never leave a blank — there is no negative marking.
Common Traps
Watch for 'always,' 'never,' and 'only' — these absolute words often indicate a wrong answer. Police law is full of exceptions.
Scenario Focus
Read the scenario carefully before the question. Identify the specific power, offence, or procedure being tested. Do not let the story distract you from what is actually being asked.
Retake Policy
If you fail, you can retake at the next sitting (approximately 6 months). There is no limit on attempts. Many successful sergeants passed on their second or third attempt — perseverance matters.
Pass Rate Context
With a ~42% pass rate, most people sitting the exam fail first time. This is not a reflection of ability — it reflects the standard of preparation required. Plan for 6 months of serious, structured study.

Inspector vs Sergeant: The Inspector exam covers all Sergeant-level legislation plus supervisory management principles and additional legislation. The questions require you to apply law at a supervisory level — not just as a practitioner. Expect scenario complexity to be significantly higher.
Key Legislation Areas: Inspector Focus
Crime (Inspector Level)
- All Sergeant-level legislation, plus deeper application to supervision of investigations
- Proceeds of Crime Act 2002 — asset recovery, cash seizure, money laundering
- Serious Organised Crime and Police Act 2005
- Counter-terrorism legislation (Terrorism Act 2000, Counter-Terrorism Acts 2008/2019)
- Computer Misuse Act 1990 — cyber-enabled crime
- Corporate Manslaughter and Corporate Homicide Act 2007
Evidence & Procedure (Inspector Level)
- PACE and Codes (full, with emphasis on Code E — audio recording, Code F — video)
- Disclosure regime under CPIA 1996 — inspector's supervisory role
- Special measures (YJCEA 1999) — decision-making authority for Inspectors
- Expert evidence and forensic integrity
- Civil recovery and asset management orders
General Police Duties (Inspector Level)
- Public Order Act 1986 — command of public order operations
- Civil Contingencies Act 2004 — emergency planning
- Human Rights Act 1998 — proportionality in operational decision-making
- Police Reform Act 2002 — PCSOs and delegation of powers
- Equality Act 2010 — operational and HR implications
- Data Protection Act 2018 / UK GDPR — intelligence handling
Supervisory Management (Inspector-Specific)
- Management of investigations — decision-making logs, NIM
- National Intelligence Model (NIM) — strategic intelligence products
- Performance management frameworks (HMICFRS inspection criteria)
- Resource deployment under operational pressures
- Managing staff welfare, sickness, and misconduct as a supervisor
NPPF Steps 1–4: Inspector Overview
150 MCQ, 3 hours. Inspector exam typically in May and November. Same format as Sergeant but with broader and deeper legislation, plus supervisory management questions. Pass rate approximately 35–45%.
Leadership Evidence Requirements
Inspector portfolios must demonstrate leadership at team and operational level — not individual task completion. Each piece of evidence should show you directing, supervising, and developing others, not just doing the job yourself.
Managing a team member's personal crisis while maintaining operational effectiveness. Adjusting command style for different individuals under pressure.
Making and standing behind difficult tactical decisions in live operations. Owning mistakes and learning from them publicly with the team.
Partnership working with CPS, local authority, IOPC, or other agencies. Cross-borough or multi-agency operation coordination.
Inspiring a team through a period of significant change or austerity. Maintaining morale and performance under resourcing pressure.
Using NIM products to drive patrol strategy. Reviewing investigation decision logs and redirecting resource based on intelligence.
Implementing new community engagement approach. Using data analytics to improve response times or reduce crime in a specific area.
6-Month Study Plan
Cover all Sergeant-level legislation plus POCA 2002, terrorism powers. Focus on supervisory application — how would you manage a team investigating these offences?
Disclosure, PACE Code E/F, special measures. Add NIM and performance management frameworks — these are Inspector-specific and often neglected.
Public order command, civil contingencies, HRA proportionality analysis. Inspectors are expected to apply HRA principles to real operational decisions.
Complete 3+ full mocks. Aim to simulate exam conditions exactly — no notes, no pausing. Track your score by subject area.
Revise weakest areas. Begin identifying portfolio evidence. The best candidates work on Steps 1 and 2 simultaneously from Month 4 onwards.
3 Sample Inspector Questions with Explanations
The Inspector Difference: Strategic Thinking
The critical distinction between a strong sergeant candidate and a strong inspector candidate is the shift from “what would I do” to “how would I direct, resource, and quality-assure a team doing this?” In the exam, interview, and portfolio, you must consistently demonstrate thinking one level above your current rank. Resource management, supervisory accountability, and strategic perspective should run through every answer.
