    Assessment & clinical reasoning
  2. Sets functional, patient-owned goals, chooses validated outcome measures, and uses the results to progress, change or discharge treatment.

    Goal setting & outcome measurement
  3. Chooses interventions with reference to current evidence and guidelines, and can explain when and why they deviate from them for a specific patient.

What they are really assessing

Interviewers rarely score whether you seemed nice. They score against a model like this one, usually without telling you it exists. Each competency has a weak, adequate and strong shape, and the difference is almost always the level of specific detail you volunteer without being asked.

Assessment & clinical reasoning

Conducts a structured assessment, forms a working hypothesis about impairment and function, and adjusts the plan as findings emerge.

Weak
Describes assessment as running through a standard form; cannot explain why particular tests were chosen or what a finding changed in their thinking.
Adequate
Explains the assessment components used for a typical case and the diagnosis reached, but reasoning is linear and does not mention differentials or red flags considered.
Strong
Presents a specific patient: the subjective findings, the hypotheses, the tests chosen to confirm or exclude them, red flags screened, and how an unexpected finding changed the plan or led to referral.

Goal setting & outcome measurement

Sets functional, patient-owned goals, chooses validated outcome measures, and uses the results to progress, change or discharge treatment.

Weak
Goals are stated as clinician goals ('improve range of motion'); no outcome measure named; cannot say how discharge decisions are made.
Adequate
Names an outcome measure used and a functional goal agreed with a patient, but cannot show the scores over time or how the results changed treatment.
Strong
Gives a case with the patient's own goal, the baseline and follow-up scores on a named measure, the point at which the plan changed, and the discharge criteria and outcome.

Evidence-based practice

Chooses interventions with reference to current evidence and guidelines, and can explain when and why they deviate from them for a specific patient.

Weak
Justifies interventions by 'that is how I was taught' or 'it works for me'; cannot name a guideline or study relevant to their common conditions.
Adequate
Cites a guideline or evidence for a common condition and applies it, but has not changed their practice recently and cannot describe weighing evidence against patient preference.
Strong
Describes a practice change they made after new evidence, names the source, explains how they judged its quality and relevance, and gives a case where they deviated from the guideline and why.

Patient engagement & adherence

Builds the patient's motivation and understanding so that home programmes and lifestyle changes actually happen, adapting to literacy, language and circumstances.

Weak
Blames non-adherence on patients being 'lazy' or 'not motivated'; the home programme is a handout with no adaptation or follow-up.
Adequate
Describes explaining the programme and checking at the next visit, with one example of simplifying for a patient, but no method for finding out why adherence failed.
Strong
Describes a non-adherent patient, how they explored the barriers (pain, beliefs, transport, work), what they changed (dose, format, family involvement), and the measured result.

Interdisciplinary collaboration

Contributes assessment findings to the multidisciplinary team, negotiates shared goals, and refers or defers appropriately across professions.

Weak
Describes other professions only as people who send referrals; cannot give an example of disagreeing with a doctor or another therapist about a plan.
Adequate
Describes attending MDT meetings and contributing to discharge planning, but the example of joint decision-making is generic and the outcome unclear.
Strong
Gives a case of conflict or gap between professions (e.g. discharge readiness, equipment, safe swallow), what they presented as evidence, how the disagreement was resolved, and the patient outcome.

Caseload & time management

Manages a caseload with waiting lists, acute and chronic patients, notes and admin, prioritising by clinical need and risk rather than convenience.

Weak
Describes seeing patients in order of arrival or booking; no method for prioritising; notes are done 'when there is time'.
Adequate
Has a prioritisation approach (acute first, discharge-critical next) and keeps notes current, but cannot describe managing a waiting-list crisis or protecting time for complex cases.
Strong
Describes a period of caseload overload: the triage criteria they used, which patients they discharged or shortened, how they raised capacity with their manager, and what the data showed afterwards.

Scope, safety & professional boundaries

Practises within HPCSA scope and competence, screens and acts on red flags, maintains boundaries with patients, and keeps records that would stand up to scrutiny.

Weak
Cannot name red flags for their common presentations; says boundaries have 'never been an issue'; record-keeping is described as minimal.
Adequate
Names red flags and an example of onward referral, and knows the boundary rules, but cannot describe a hard case or an ethical dilemma they had to work through.
Strong
Describes a red-flag case they caught and referred with the specific signs, an ethical or boundary situation (gifts, dual relationship, adolescent consent) and how they handled it, and what their records include and why.
