OET for Dietitians — HCPC & AHPRA Pathway

Internationally trained dietitians need Grade B across all four OET sub-tests for HCPC (UK) or AHPRA (Australia) registration. The Writing sub-test asks for structured prose communication of nutritional findings and plans.

Quick answer

Internationally trained dietitians need Grade B (350) in each of the four OET sub-tests for HCPC (UK) and AHPRA (Australia) registration. The Writing sub-test tests your ability to communicate nutritional findings and recommendations to a non-dietitian addressee in 250 words of paragraph prose — not bullet-point plans. Most marks are lost on Genre & Style.

Key takeaways for dietitians

  • Required grade: HCPC and AHPRA require Grade B (350) in Writing.
  • Most common letter type: GP or MDT referral with nutrition support plan.
  • Top criterion lost: Genre & Style — bullet-point plans rather than paragraph prose.
  • Validity: 2 years from test date.

The Two Letter Types Dietitians Write Most

1. Referral / advice letter

Sent to a GP or MDT recommending a nutrition support plan — refeeding risk, malnutrition, supplementary nutrition, or specialised dietary intervention.

Marking watch-out: Genre & Style — write the plan as connected prose, not bulleted lists.

2. Discharge / handover letter

Communication after a nutritional intervention summarising progress and ongoing recommendations. Often addressed to a community dietitian or GP.

Marking watch-out: Conciseness — focus on outcomes and ongoing plan, not the full intervention recap.

The Three Mistakes That Cost Dietitians Their Grade

1

Use paragraph prose, not bullet recommendations

Stop listing nutrition recommendations as bulleted plans. Rewrite as flowing sentences. Mapped criterion: Genre & Style.

2

Contextualise nutrition terminology

Stop using MUST scores, refeeding-risk shorthand, or micronutrient abbreviations without context for GP addressees. Expand on first use. Mapped criterion: Language.

3

Prioritise findings linked to the recommendation

Stop reciting the full dietary history. Include only findings that justify the recommendation or referral request. Mapped criterion: Conciseness & Clarity.

Frequently Asked Questions

Which regulators accept OET for dietitians? +

The UK HCPC and Australian AHPRA both accept OET for dietetic registration. Grade B (350) is required across all four sub-tests. Combined sittings within the validity window are accepted.

What letter type do dietitians write in OET? +

Dietitians typically write a referral letter to a GP or MDT (recommending nutrition support plans) or a discharge letter following a nutritional intervention. Case notes commonly include BMI, biochemistry markers, dietary history, and ongoing nutrition support plans.

Why do dietitians lose marks in OET Writing? +

Two patterns are common. First, over-listing dietary recommendations as bullet points instead of structured prose (Genre & Style). Second, technical nutrition terminology — MUST scores, refeeding risk, micronutrient deficiencies — used without context for non-dietetic addressees (Conciseness & Clarity).

Is dietitian-specific case-note practice essential? +

Yes. Generic medical case notes do not capture nutritional assessment workflows. Profession-aware correction ensures feedback covers MUST scoring, refeeding considerations, and the right register for MDT versus GP communication.
