About this exam

The Perito Médico Federal is the physician who performs medical assessments for Brazil's federal social security system (RGPS), mainly for the INSS. The role sits at the intersection of clinical medicine, social security law and forensic practice: the physician examines claimants, documents findings, decides whether and for how long work capacity is impaired, and links incapacity to work-related causes when the evidence supports it. Candidates are licensed physicians who want a public-sector career combining clinical judgment with administrative and legal reasoning. Preparation is broad rather than deep in any single specialty. Expect social security and labour legislation, the conceptual and practical core of disability assessment, occupational medicine, internal medicine across major specialties, psychiatry, orthopaedics and traumatology, legal and ethical medicine, administrative and constitutional law, Portuguese, and basic logic and computing. Strong candidates build a study calendar weighted to the highest-percentage domains, read primary legislation rather than summaries, and practise written answers because the discursive test rewards structured, precise prose. Clinical experience helps, but the exam tests how well you can justify a conclusion in writing. The official notice (edital) governs every logistical detail, and the organising body publishes current figures for vacancies, dates and scoring.

What you'll study

Common questions

About Perito Médico Federal (INSS / MPS) preparation

What does the exam actually test?

A broad medical and legal syllabus rather than one specialty. The heaviest weight falls on social security law and on the theory and practice of disability assessment, followed by clinical medicine, occupational medicine, psychiatry and orthopaedics. Legal, ethical, administrative and language components complete the picture. The organising body's edital lists the exact programme and weights.

Is the exam hard?

It is competitive and content-heavy. The difficulty comes from breadth: you must move between a psychiatric assessment, a legal definition of incapacity and a Portuguese writing task without losing precision. Physicians who know medicine well but have never studied social security legislation typically find the legal and assessment domains the hardest.

How many questions and how long is the test?

The organising body publishes the current number of items, the duration and the scoring rules in the official edital for each competition. Do not rely on numbers from previous editions, because they change. Check the official notice and the organising body's website before planning your exam-day strategy.

Can I retake the exam if I fail?

Yes. There is no lifetime limit on attempts; you simply enter the next competition. Some candidates sit several editions before approval. Each new edital sets its own rules, so confirm any specific restrictions, such as validity of previous results, in the current official notice.

How long should I prepare?

Most successful candidates study for many months, often close to a year, because the syllabus is wide. A realistic plan allocates the largest blocks to social security law and disability assessment, keeps clinical medicine in continuous review, and reserves weekly time for written practice and Portuguese. Adjust the plan once the edital confirms the programme.

In what order should I study the subjects?

Start with social security law and the concepts of disability assessment, since they frame everything else and appear inside clinical questions. Add clinical, psychiatric and orthopaedic topics in parallel, then occupational medicine and legal ethics. Keep Portuguese and logic as steady short sessions. Finish with timed mixed practice and full written simulations.

Why do candidates fail the written test?

Common causes are answering the question asked only loosely, omitting the legal basis, and writing long unstructured paragraphs. Examiners reward a clear structure: identify the issue, state the rule, apply it to the facts, conclude. Practise under time pressure and have someone review your answers for precision and organisation, not just content.

What is the biggest mistake in the objective test?

Treating clinical knowledge as sufficient. Many items ask you to classify incapacity, judge causation or choose the correct administrative procedure, so a clinically correct answer can still be wrong. Read the stem carefully, watch for absolute words, and eliminate alternatives that contradict the legal framework before choosing.

Does clinical experience guarantee approval?

No. Experience helps with interpretation and with judging real-world plausibility, but the exam tests structured reasoning and legal knowledge that practice alone does not teach. Experienced physicians still need to study the legislation, learn the assessment framework and practise objective and written questions systematically.

Where do I confirm dates, fees and vacancies?

Only in the official edital published by the organising body for the current competition. That document sets dates, fees, vacancy distribution, scoring and appeal rules, and it changes between editions. The organising body's website is the authoritative source; treat any other figure as unverified until the notice confirms it.
