The Enem reaplication, held on December 16 and 17, 2025, featured at least two questions with logical structures identical to those in study materials attributed to medical student Edcley Teixeira. The Inep released the test booklet on December 23, and Folha identified similarities in math and combinatorics problems. Edcley denies any leak, crediting the matches to analysis of exam patterns.
The Enem 2025 reaplication, intended for candidates unable to take the original exam due to reasons like contagious diseases or logistical issues, took place on December 16 and 17. The National Institute for Educational Studies and Research Anísio Teixeira (Inep) released the test booklet on December 23, revealing similarities with materials shared by medical student Edcley Teixeira from the Federal University of Ceará.
Folha compared the questions to digital study guides attributed to Edcley, such as the "Estarão no Enem" folder, sourced from social media and online groups. In one math question, both involve purchasing 40 televisions at R$1,200 each, with a 60% freight cost reduction, requiring similar calculations to compare expenses or additional quantities. Another match appears in combinatorics: forming 13-digit codes starting with 7, 8, and 9, solved using the multiplicative principle.
Inep president Manuel Palacios stated that the review found no evidence of prior access to the exam. "No one saw the test," he said in a prior interview with Folha. He attributed the coincidences to over 4,000 pre-tested questions by the institute, vital for exam calibration. Palacios stressed that the similarities do not undermine the test's security or score validity, as no questions are identical.
Edcley, with 13 Enem participations, denied any leak on December 23. He described his approach as statistical and pedagogical analysis of the Inep's reference matrix, without privileged access. The case gained national attention after Edcley predicted questions from the November 2025 regular application, prompting the Ministry of Education (MEC) to annul three items and involve the Federal Police. He also foresaw the testlet format, which debuted in Enem 2025.
Other parallels include excerpts from Machado de Assis's short story "O diplomático" in Portuguese language, and topics on the National Program for Medicinal Plants and Phytotherapeutics in natural sciences. The reaplication comprised 180 questions and an essay on "the minimum age for work as a form of child protection." The Enem PPL, for people deprived of liberty, had its answer key released simultaneously.
