Since 1995, Brazil has implemented a broad range of large scale assessments at different scales.
In a decentralized country such as Brazil, many regions combine national assessments with their own tests and accountability policies, which often have career and financial implications for schools and teachers.
This is also the case of Minas Gerais, especially since the introduction of the Sistema Mineiro de Avaliação da Educação Pública (SIMAVE) in the year 2000.
