Os exames de admiss\u00e3o ocorrem anualmente e s\u00e3o divididos em duas partes: a primeira ocorre geralmente entre junho e agosto e \u00e9 chamada de Exame de Qualifica\u00e7\u00e3o. Essa fase \u00e9 marcada por uma prova m\u00faltipla-escolha, com 60 quest\u00f5es. A segunda, \u00e9 restrita aos candidatos que passaram pela primeira fase e \u00e9 chamada de Exame Discursivo, onde o candidato deve realizar duas provas de conhecimento especifico, portugu\u00eas instrumental e reda\u00e7\u00e3o.
