HCPC vs AHPRA OET Scores: The Allied Health Registration Arbitrage You Need to Understand

Two Regulators, Two Scoring Models, One Test

Allied health professionals — physiotherapists, radiographers, occupational therapists, dietitians, podiatrists — targeting either the UK or Australia face the same OET, but two fundamentally different scoring frameworks depending on which regulator they are satisfying.

The UK’s Health and Care Professions Council (HCPC) uses an aggregate total model: 1400 points across four sub-tests, with a floor of 300 in each.

Australia’s AHPRA (from April 2026) uses individual component minimums: 350 in Listening and Writing, 360 in Reading and Speaking, with no aggregate pathway to compensate for a below-threshold component.

This difference is not just administrative. It is a genuine registration arbitrage opportunity — a way of choosing your target market strategically based on your actual English language profile. And it has direct implications for how you prepare for OET Writing specifically.

The HCPC Aggregate Model: How It Works in Practice

HCPC accepts OET for chiropodists/podiatrists, dietitians, occupational therapists, physiotherapists, radiographers, and speech and language therapists (SLTs). For all professions except SLTs, the requirement is:

• No individual sub-test score below 300 (Grade C+, the floor)
• Total across all four sub-tests: 1400 or above

This means a physiotherapist could achieve the following and meet the HCPC standard:

The Writing component here is exactly at the floor — the lowest permissible score. But the aggregate total of 1440 exceeds the 1400 threshold. The application succeeds.

This is the arbitrage: a physiotherapist with genuinely strong Listening and Speaking skills and weaker writing can still meet HCPC’s requirements, provided Writing does not fall below 300.

The AHPRA Model: Strict Individual Minimums (April 2026 Update)

AHPRA transitioned to a numeric OET scoring system from 23 April 2026. The letter-grade system (B, C+) is replaced by specific point thresholds for tests taken on or after that date:

There is no aggregate total pathway. If Writing is 340 and all other components meet or exceed their minimums, the application fails — because Writing is 10 points below its individual threshold.

This is a harder target for candidates whose Writing is their weakest component. The safety net of a high Listening or Speaking score compensating for a Writing shortfall that exists under HCPC rules does not exist under AHPRA rules.

What This Means for Your Test Strategy

If you are a physiotherapist or radiographer considering both Australia and the UK as destination options, your OET score profile may make one route more accessible than the other right now — even if both remain your long-term goals.

Scenario A: Strong oral skills, developing writing

A physiotherapist from the Philippines who scored Listening 400, Reading 370, Speaking 380, Writing 290 has a total of 1440 — meeting HCPC’s requirements. They cannot register with AHPRA because Writing (290) is below the 350 minimum.

Strategy: Register with HCPC in the UK first. Work, build clinical UK experience, retake Writing to reach 350. Apply for AHPRA once Writing is at threshold.

Scenario B: Strong writing, variable Speaking

A radiographer from India who scored Listening 360, Reading 370, Writing 370, Speaking 300 has a total of 1400 — exactly meeting HCPC’s requirement. They cannot register with AHPRA because Speaking (300) is below the 360 minimum.

Strategy: Same as above — UK HCPC first. Target Speaking improvement for the Australia pathway.

Scenario C: Consistent moderate performer

An occupational therapist who scores Listening 360, Reading 360, Writing 340, Speaking 340 has a total of 1400 — meeting HCPC. Writing (340) and Speaking (340) are both below AHPRA’s minimums of 350 and 360 respectively.

Strategy: HCPC first. For AHPRA, the Writing criterion is the more achievable target (+10 points to 350) while Speaking improvement (+20 points to 360) requires more work.

The Writing Criterion Under Both Systems

Even under HCPC’s more forgiving aggregate model, Writing at exactly 300 is a risky strategy. The 300 score (Grade C+) represents the bottom of the acceptable range — and a candidate who sits within 10–20 points of that floor is vulnerable to a slight shift in performance on test day.

More practically: Writing at 300–320 suggests the candidate is not communicating at the clinical standard their patients and colleagues will expect. The HCPC minimum is a registration threshold, not a performance standard. A physiotherapist who genuinely wants to thrive in a UK clinical setting needs writing that functions at B grade or above — for patient records, MDT correspondence, referral letters, clinical reports.

This is where OET Writing preparation serves a dual purpose: it demonstrates competence for the regulator and builds the actual skill the clinical role requires.

The Profession-Specific Content Challenge

OET Writing for physiotherapists uses physiotherapy case notes. This matters for preparation. A nurse-focused OET preparation tool uses nursing scenarios — referrals to GPs, discharge summaries, community nurse handovers. These are not the same clinical contexts, and the expected content in a physiotherapy letter differs from what a nursing case would require.

A physiotherapy referral letter might centre on: a functional assessment, mobility status, falls risk, specific joint or muscle findings, home adaptation recommendations, or a return-to-work plan. The reader calibration is different — often a GP, a specialist consultant, or a community physiotherapy team rather than a hospital ward nurse.

Generic preparation materials, and generic AI feedback, do not account for this profession-specific content layer. The Content criterion requires that your letter includes the right information for the clinical context. A physiotherapy letter that reads like a nursing discharge summary will lose marks on both Content and Genre & Style.

Planning Your Registration Pathway

If you are an allied health professional with a clear destination preference — UK or Australia — your OET strategy is straightforward: meet the target regulator’s requirements as efficiently as possible.

If you are undecided or exploring both markets, the arbitrage insight is this: HCPC is accessible to candidates with Writing at Grade C+ (300+) if their other sub-tests are strong. AHPRA requires Writing at 350 regardless. The UK route to working and settling is therefore more accessible sooner for candidates with uneven profiles.

Once in the UK on HCPC registration, building Writing to 350+ for the Australian route is a realistic and financially strategic goal. You are earning a UK salary, accruing NHS pension, building towards ILR — while also working toward the AHPRA threshold that opens a second career option.
