Registrations for the first phase of the national secondary school exams opened on 6 March and run until 19 March; students may also register for self‑proposed 9th‑grade tests. The Directorate‑General for Education (Direção‑Geral da Educação) published the registration rules: internal and self‑proposed students must register, take a Portuguese exam and choose two additional subjects according to the instructions. Students and parents should complete registrations before the 19 March deadline and follow the DGE guidance on subject choices.
