Medical and fitness assessments are common prerequisites for safety‑critical or physically demanding roles in South Africa — for example mining, transport (drivers/operators), security, firefighting, and some healthcare roles. Knowing what to expect, your legal rights, and how to prepare will help you perform well and protect your privacy. This guide covers what employers typically test for, how to prepare practically and legally, and what steps to take if you have concerns.
Why employers require assessments (and the legal framing)
Employers may require assessments when a job has inherent medical or physical requirements that are essential for safe performance. South African law recognises that such checks are lawful where they are:
- Job‑related and necessary for the inherent requirements of the position.
- Applied consistently and reasonably across candidates.
- Conducted in a way that respects privacy and data protection rules, including POPIA.
If an employer uses medical or fitness results to make hiring or accommodation decisions, those decisions must align with the Employment Equity Act and non‑discrimination provisions. For an overview of how Employment Equity affects interviews and hiring processes, see Interview Preparation South Africa: What Candidates Need to Know About the Employment Equity Act and Hiring.
Common types of medical and fitness assessments
| Assessment | Purpose | Typical roles | How to prepare | Legal considerations |
|---|---|---|---|---|
| Pre‑employment medical exam | General health screening, fitness to perform duties | Mining, manufacturing, healthcare, heavy plant operators | Bring ID, consent forms, list of medications, recent medical records | Must be job‑related; results are sensitive personal data under POPIA |
| Functional Capacity Evaluation (FCE) | Tests physical ability to do job tasks (lifting, endurance) | Manual labour, lifting‑intensive roles | Wear comfortable clothing; avoid heavy meals before test | Employer must justify necessity |
| Drug & alcohol screening (urine/breath/hair) | Safety / impairment detection | Drivers, pilots, security | Avoid alcohol; follow pre‑test instructions from provider | Chain of custody and POPIA compliance required |
| Audiometry & vision tests | Assess sensory fitness for safety‑critical tasks | Drivers, machine operators, pilots | Bring spectacles/contact lens details | Results must be handled confidentially |
| Chest X‑ray / TB screening | Occupational health surveillance in certain sectors | Mining, healthcare | Inform provider of pregnancy; follow X‑ray prep | Screening must be proportional; employer to follow occupational health guidelines |
| Blood tests (cholesterol, glucose, HIV — limited) | Detect health risks relevant to job | Varies — only if job‑related | Fast if requested; disclose medications | HIV testing is sensitive: generally not permitted unless occupational exposure risk justifies it; see Employment Equity Act |
| Psychological assessment | Evaluate mental fitness or cognitive suitability | Pilots, safety‑critical roles | Sleep well; take instructions seriously | Psych testing must be valid, reliable, and job‑related |
Practical preparation checklist (what to bring and do)
- Confirm scope: Ask HR which tests will be done, where, and who performs them. Request written information and a consent form in advance.
- Bring documents:
- ID and appointment confirmation
- List of current medications and dosages
- Relevant medical reports, vaccination records, or specialist letters (if they affect results)
- Follow test instructions: e.g., fasting for blood tests, avoid alcohol or strenuous exercise before fitness tests.
- Dress appropriately: comfortable clothing and footwear for physical tests.
- Be punctual: allows time for consent and explanation.
- Ask about results: request how and when you’ll receive results and who will have access.
Your rights and data protection (POPIA and confidentiality)
Medical information is classified as special personal information and receives higher protection under POPIA. Key rights:
- Informed consent: You should be told the purpose of tests and must consent before collection.
- Limited access: Only authorised persons (occupational health professionals, designated HR) should access your medical data.
- Right to copies: You can request a copy of test results held by the employer or the medical provider.
- Right to correction/objection: If you believe the data is inaccurate, you may request correction, or object to unlawful processing.

Disclosing pre‑existing conditions — how much to reveal
Disclosing a medical condition is a balance between honesty and protecting your privacy. If a condition affects safe performance or requires reasonable accommodation, disclose it. For tips on framing sensitive disclosures during interviews, read How to Disclose Sensitive Information During SA Interviews Without Jeopardising Your Candidacy.
Remember:
- Only provide information relevant to job performance.
- You can provide a doctor’s note explaining limitations and suggested accommodations.
- Employers must consider reasonable accommodation as required by the Employment Equity Act.
If you disagree with results or feel mistreated
- Request a copy of the assessment report and the testing protocol.
- Ask for a second opinion (independent medical examination). Employers commonly fund an independent review if requested.
- Raise a formal grievance with HR. Document communications in writing.
- Seek legal or union support if you suspect discrimination or unlawful processing. The CCMA and Department of Labour handle employment disputes; data protection issues can be raised with the Information Regulator.

Role‑specific considerations
- Miners: additional statutory medical surveillance and TB screening; special mining medicals may apply.
- Drivers and transport: strict alcohol and drug testing, vision and hearing standards.
- Foreign nationals: ensure you meet work visa medical requirements; check Work Visas and Documentation for Foreign Applicants to South Africa: Interview Stage Requirements.
Timeline and costs
- Employers normally arrange and pay for mandatory pre‑employment tests.
- Tests may take a few hours to several days (if lab analysis is required). Ask HR for expected timing so you can plan.
- If you request an independent medical assessment, employers may pay or require sharing costs — clarify this in advance.
Additional hiring checks and how they intersect
Medical and fitness assessments are often part of a broader screening process that can include qualification verification, background checks and equity considerations. To prepare holistically:
- Verify your qualifications early: SAQA Verification and Qualification Checks: How to Prepare and Speed Up Your Background Screening.
- Understand how BEE and Employment Equity can affect the process: BEE and Recruitment: How Employment Equity Affects Interview Processes in South Africa.
- Learn what recruiters look for and preempt common pitfalls: What Recruiters Look for in Background Checks: Common Issues and How South African Candidates Can Preempt Them.
Final tips — day before and day of the assessment
- Rest and hydrate the day before.
- Avoid alcohol and recreational drugs for at least 24–48 hours (or as advised).
- Have a light meal if you’re not fasting for blood tests.
- Bring all documentation and a calm, clear mind — explain medications and health history honestly to the occupational health practitioner.

Preparing properly for employer‑required medical and fitness assessments improves your chances of a smooth process and helps protect your rights. When in doubt, ask for written information, keep records, and seek independent advice if you feel your health information has been mishandled or used unfairly.
