PSRAS Portfolio Guide — Part A & Part B

How to build and submit your nine-case PSRAS portfolio: official requirements, case reports, breadth, deadlines, and what assessors actually mark — verified against PSRA 2025 and assessment organisation guidance.

Last updated: 5 June 2026 · Author: Robert Cashman, Duty Solicitor & Higher Court Advocate

Verify with your assessment organisation

Case counts and deadlines below are verified against the Police Station Register Arrangements 2025 and Datalaw's published portfolio guide. Cardiff University may differ on templates and submission dates — always use your current candidate handbook.

Where the portfolio sits in PSRAS

The portfolio is the supervised competence evidence between the written examination and the Critical Incidents Test (CIT). It is assessed by Cardiff University or Datalaw against the SRA Standards of competence.

  1. Step 1

    Enrol with Cardiff or Datalaw

    Register with an SRA-authorised assessment organisation. You receive regulations, handbook, and timetable.

  2. Step 2

    Pass the written exam (or prove exemption)

    The written examination must be passed before Part A portfolio cases begin (Datalaw process). PSRA 2025 also requires written pass (or exemption) before DSCC probationary registration.

  3. Step 3

    Complete Part A (four case studies)

    Part A Stage 1: two cases observing your supervising solicitor. Part A Stage 2: two cases where you advise while observed. Submit Part A for assessment; cases must usually be within three months of submission (Datalaw).

  4. Step 4

    Probationary registration (ADMIN 2)

    Once Part A and the written exam (or exemption) are passed, your supervising solicitor submits ADMIN 2 to the DSCC. You receive a probationary PIN — typically within 14 days of a complete application (PSRA 2025).

  5. Step 5

    Complete Part B (five case studies) and pass the CIT

    After probationary registration you may undertake Part B (five unsupervised cases) and the Critical Incidents Test — in either order (Datalaw). All nine portfolio cases must be submitted within 12 months of your first case (Datalaw).

  6. Step 6

    Full accreditation

    When Part B portfolio and CIT are passed, you become a fully accredited police station representative on the Register.

Official case requirements

The portfolio contains nine detailed case studies, each involving advice and attendance at a police interview (Datalaw). This replaces older informal guidance referring to "6 + 10 attendances" — those numbers are not in PSRA 2025 or Datalaw's published requirements.

Datalaw

Nine cases in two parts (2+2+5). Part A may be submitted for technical compliance before probationary PIN. Part B and CIT available once probationary status is granted. Confirm current submission deadlines on the Datalaw timetable.

Cardiff University

Cardiff runs the same regulated PSRAS qualification but may differ on templates, submission dates, and classroom support. Download Cardiff's current candidate handbook — do not assume Datalaw numbers differ without checking.

Probationary rules while building the portfolio

  • Probationary representatives must not take on duty cases or indictable-only cases (PSRA 2025).
  • Probationary representatives may only advise on own-client cases assigned to the provider where their supervising solicitor is based (PSRA 2025).
  • Part A Stage 1 cases may include duty-referred and indictable matters because the supervising solicitor leads (Datalaw).
  • Part B cases: own-client summary or either-way offences only for probationary reps (Datalaw).
  • Every case must include an interview where the suspect is questioned by a constable (Datalaw).
  • You must have a recognised supervising solicitor at all times throughout accreditation (Datalaw / PSRA 2025).

Deadlines and PIN suspension

Before probationary PIN

Pass written exam (or prove LAA exemption) and pass Part A portfolio assessment. Supervising solicitor submits ADMIN 2 with evidence of passes.

First 6 months after DSCC registration

Pass at least one of Part B portfolio or CIT. If neither is passed within 6 months, PIN is suspended until one test is passed (PSRA 2025; Datalaw mirrors this).

12-month probationary period

Pass all remaining tests (Part B and CIT) within 12 months of registration, or within the extended two-period structure if one test was missed at 6 months (PSRA 2025).

Portfolio case age (Datalaw)

Part A cases must be within three months of submission date. Full nine-case portfolio must be submitted within 12 months of the first case.

SRA competence mapping

Each case report should demonstrate the SRA assessment outcomes. Map your sections as follows:

Assessment outcome 1 — Role of the rep

Client details; initial contact; explaining your role (Code C Note 6D)

Show you understand authority to act, third-party instructions, and the rep's objectives at custody.

Assessment outcome 2 — Criminal process

Case details; arrest/detention analysis

Record and test arrest under PACE s.24 and Code G; detention under s.37. Datalaw assessors expect challenge where grounds are weak.

Assessment outcome 3 — Crimes and defences

Offence elements; advice section

Identify offence elements, potential defences, and tie advice to the allegation — not generic templates.

Assessment outcome 4 — Rules of evidence

Disclosure analysis; interview strategy

Explain evidential significance of what was disclosed, missing, or said/not said in interview.

Assessment outcome 5 — Police station procedure

Custody record; samples; identification; reviews

Cover PACE Code C procedure: detention clocks, reviews, appropriate adults, samples (PACE ss.61–63), identification (Code D) where relevant.

Assessment outcome 6 — Interview

Interview section; interventions

Describe strategy (answer, no comment, prepared statement), interventions on improper questions, and whether strategy held.

Assessment outcome 7 — Ethics and professional conduct

Reflection; conflicts; contract compliance

Reflect on performance; note DSCC contact rules (e.g. initial contact within 45 minutes under SCC — Datalaw assessor guidance).

Case report blueprint

1. Client and case details

Anonymised client (e.g. "Mr X"), age, offence type, UFN, date, station. Never use real names or identifying details. State how you were instructed and your role (observe / lead / unsupervised).

Assessor focus: Assessors cannot infer knowledge you do not record — write it down (Datalaw assessment board).

2. Arrest, detention, and delay

Where the client was arrested, test s.24/Code G necessity and s.37 detention grounds. Explain any delay (transfer, hospital, rest periods) and its effect on the custody clock.

Assessor focus: Increasing failures where candidates omit initial telephone contact or fail to explain rest/delay (Datalaw).

3. Disclosure analysis

What the police disclosed (initial and further), what was missing, what you chased, and why it mattered for advice. Link to Code C para 11.1A and fairness.

Assessor focus: Thin disclosure supporting no comment must be explained with CJPOA s.34 risks to the client.

4. Legal advice and strategy

Answer, no comment, or prepared statement — with reasons tied to disclosure, offence elements, and adverse-inference position. Record instructions clearly.

Assessor focus: Generic pasted advice fails — every section must be case-specific.

5. The interview

Dynamics, representative interventions, client performance, and whether the strategy held. Note oppressive or misleading questions you challenged.

Assessor focus: Show practical decision-making, not textbook summaries.

6. Reflection

What went well, what you would do differently, and what you learned. Supervisors should help identify gaps before submission.

Assessor focus: Reflective voice matters more than length — assessors look for self-awareness (SRA external examiner themes).

Breadth matrix (spread across 9 cases)

Datalaw requires a good range of issues and offences across the portfolio — not nine identical shop-theft files. Plan breadth from case one:

  • Violence / public order: Assault, ABH, affray, domestic incident
  • Dishonesty: Theft, fraud, handling, burglary
  • Drugs / road traffic: Possession, supply, drink/drug drive
  • Youth / vulnerability: Juvenile with AA; mentally vulnerable adult
  • Identification: Code D procedure; VIPER; street ID challenge
  • Adverse inference: No comment or prepared statement with s.34 explanation
  • Samples / forensic: Fingerprints, DNA, non-intimate samples

Supervisor feedback

Part A Stage 2 requires signed written feedback from your supervising solicitor (Datalaw — upload as PDF for cases 3 and 4). Part B feedback sessions are recommended even when not mandatory in the submission. Supervisors must meet PSRA Crime Category Supervisor standards — see our Find a Supervising Solicitor guide.

Submission workflow

  1. Confirm case order (usually descending date order for Datalaw online submission).
  2. Part A: upload each case PDF with UFN, date, supervisor name and roll number. Cases 3–4 require supervisor feedback PDF (Datalaw).
  3. Await technical compliance pass on Part A before DSCC probationary application (Datalaw workflow).
  4. Part B: upload five cases with probationary PIN, UFN, and dates.
  5. Full portfolio enters multi-stage assessment — expect feedback rounds before final pass.
  6. Cardiff candidates: follow Cardiff handbook submission method and deadlines.

Common fail patterns (assessor board)

  • Failing to record or test arrest/detention grounds (PACE ss.24, 37; Code G) — Datalaw assessment board.
  • No record of initial telephone contact or unexplained delay during rest periods — Datalaw.
  • Assessors inferring competence from unwritten assumptions — everything material must appear in the case study.
  • Generic advice paragraphs copied between cases without case-specific analysis.
  • Missing breadth across the nine cases (single offence type repeated).
  • Weak reflection — no learning point or self-criticism.

Self-assessment checklist

  • Nine cases total: 2 observe + 2 observed advising + 5 unsupervised
  • Each case includes advice and a constable-led interview
  • Client anonymised; UFN and dates correct
  • Arrest/detention tested where relevant
  • Disclosure chased and analysed
  • Interview strategy explained with s.34 where applicable
  • Supervisor feedback attached for Part A Stage 2 (Datalaw)
  • Breadth of offences and issues across the portfolio
  • Reflective learning in every case
  • Submitted within provider deadline and case-age rules

Tips for success

  • Keep contemporaneous attendance notes — you cannot reconstruct disclosure weeks later.
  • Plan breadth across nine cases from the start; do not leave identification or vulnerability to the last case.
  • Apply supervisor feedback before resubmitting — first submissions often need amendment.
  • Treat each case report as CIT preparation: explain what you would do and why.
  • Use the golden rule (Datalaw): if an issue arises in the case, deal with it in the write-up.
  • Extra real attendances beyond nine may help your skills, but only nine assessed cases go in the portfolio.

Common mistakes to avoid

  • Treating portfolio minimums as "6 + 10 attendances" — the regulated structure is nine case studies (2+2+5)
  • Starting Part A before passing the written exam (Datalaw requirement)
  • Taking indictable-only or duty cases as probationary lead adviser
  • Copy-pasting advice without case-specific disclosure analysis
  • Submitting without supervisor sign-off or mandatory feedback documents
  • Assuming assessors will infer PACE knowledge you did not write down

FAQs

How many cases are in the PSRAS portfolio?+

Nine case studies in total: Part A Stage 1 (two observed), Part A Stage 2 (two where you advise while observed), and Part B (five unsupervised). Each must include advice and a police interview (Datalaw; consistent with PSRA 2025 Part A structure).

Can I start Part A before passing the written exam?+

Datalaw requires the written exam to be passed before Part A cases begin. Secure your supervising solicitor and firm support first, but sit or obtain exemption for the written stage before counting portfolio cases.

When do I get a probationary PIN?+

After your assessment organisation passes Part A and you have passed or been exempted from the written exam, your supervising solicitor submits ADMIN 2 to the DSCC. The DSCC typically issues a PIN within 14 days of a complete application (PSRA 2025).

Must I finish the portfolio before the CIT?+

Once probationary, Part B and CIT can be undertaken in either order (Datalaw). You must pass both within the probationary deadlines (PSRA 2025).

Can I use the same co-defendant case twice?+

No — a co-defendant matter counts as one case study only (Datalaw).

Do Cardiff and Datalaw require the same number of cases?+

Both assess the same SRA-regulated PSRAS qualification. Case counts align with the nine-case structure; always confirm templates and deadlines in your provider's current handbook.

What if I miss the 6-month or 12-month deadline?+

Missing a deadline can suspend your PIN until tests are passed; extensions may be available for extenuating circumstances with evidence (PSRA 2025). Contact the DSCC and your supervisor immediately.

Can I change supervising solicitor mid-portfolio?+

The same solicitor should supervise throughout. Changing supervisor requires DSCC permission except in exceptional circumstances (PSRA 2025).
