A recent controversy has arisen regarding the Revalida exam in Brazil, aimed at foreign-educated medical professionals. An official document from the Ministry of Health, dated January 22, 2026, contradicts the correct answer provided by the National Institute for Educational Studies and Research (Inep) for one of the questions in the first stage of the exam, which took place in December 2025. The contested question concerns a case study on malaria, which candidates argue is central to their overall scores in the exam. Candidates are urging for the cancellation of question 40 due to the significant impact that an additional point could have on their final results. The Revalida exam requires candidates to answer at least 61 out of 100 objective questions correctly to qualify for the next phase of the certification process. As of the latest update on this situation, Inep has not yet responded to inquiries regarding the controversy surrounding the answer key. The implications of this issue are significant, not only for the candidates who are navigating the complex process of practicing medicine in Brazil but also for the integrity of the examination system itself. Should the question be annulled, it may lead to a ripple effect, impacting candidates' qualifications and shedding light on the procedures and accountability of educational assessments in the country.
