Questions, answered plainly.

No. For the NIE, the exam is marked against the current edition of Blackstone's Police Investigators' Manual.

For Sergeants and Inspectors, the exams are marked against the current editions of Blackstone's Police Manuals volumes 1–3: Crime, Evidence and Procedure, and General Police Duties.

You need the correct current material for your exam. Police Law Prep helps you retrieve and apply what you study. It does not replace the manuals.

The cards, overviews and questions are independently written from primary public sources. These include legislation.gov.uk, the PACE Codes of Practice, CPS guidance and Sentencing Council guidance.

Case-law summaries describe published judgments from Find Case Law and BAILII. The content is not copied from Blackstone's manuals or the College of Policing's Authorised Professional Practice.

Yes. The content sources and licences record explains each source category, the public records used and the Open Government Licence attribution.

It is a source and licensing record, not a footnote list under every individual card or question.

No. A Large Company Ltd publishes Police Law Prep independently. It is not affiliated with or endorsed by the College of Policing, any police force or any publisher.

Your account includes separate revision workspaces for the National Investigators' Examination, NPPF Sergeants and NPPF Inspectors.

Each workspace keeps its own cards, questions, mocks, review schedule and progress record.

Full access costs £15 a month, including VAT. It renews monthly, with no minimum term. One subscription covers all three exam workspaces.

Yes. Start a 7-day free trial for full access to NIE, Sergeants and Inspectors. It needs an account but no payment card, and it ends automatically.

The free NIE workspace also includes four complete NIE topics. You do not need an account or payment card for it.

Yes. Sign in on your phone, tablet or computer to continue your synced progress. Your three exam records remain separate.

Existing customers with a legacy NIE access code can still use the code option on the login page.

Your account also includes two private SIPP legal-knowledge beta workspaces, one for Sergeants and one for Inspectors. They are study-only and their coverage is incomplete: the material is mapped from the NPPF workspaces you already have, and each workspace shows its partial coverage, known gaps and exclusions before you start.

They have no readiness estimate and no standard timed mock. No claim is made about an official future format, pass mark, timing, weighting or syllabus. They are included only with this account and are not sold separately.

Each of the three complete workspaces — NIE, NPPF Sergeants and NPPF Inspectors — includes study cards, scenario-based practice questions, focused review, quick mocks, full timed mocks and a readiness estimate. Every question explains the correct answer and each wrong option, and the three workspaces contain 286 written scenarios that ask for the outcome and legal reason with no answer options.

Quick 20 mocks fit shorter study periods. The NIE full mock uses 80 questions over two hours. The Sergeants and Inspectors full mocks use 150 questions over three hours.

Each mock draws from that exam's own bank and weighting.

It compares your answers with the pass threshold for your selected exam. It is study feedback, not an official result or a guarantee that you will pass.

Each review session stops at 15 items. You still see the complete waiting count, and later sessions rotate through deferred work.
