This paper's aim was to identify the main factors influencing secondary education dropout. The data are based on a historical series developed by the National Household Sample Survey (PNAD) and a large survey conducted in Minas Gerais, Brazil, which collected diverse information from 3,418 interviewees (including students and dropouts). Cox proportional hazards regression models were estimated to identify potential correlations between intra and extra-school factors and early dropout. Another model used PNAD database, for which a Logit model was estimated, to verify nondropout rates in high schools in Minas Gerais. Some significant factors are highlighted in the results explaining dropout, such as: difficulties faced with subjects, desire for a different school, perception of better job opportunities if studies are completed, and importance assigned to school choice.
Neste trabalho avaliam-se os efeitos do Projeto Escola de Tempo Integral, desenvolvido pelo Governo do Estado de Minas Gerais desde o ano de 2007 nas escolas estaduais mineiras, nos resultados das avaliações em larga escala de Língua Portuguesa e Matemática. Nesse sentido, o projeto tem apresentado resultados positivos ao promover as proficiências dos alunos com defasagens de aprendizagem. O estudo observacional foi baseado nos resultados dos alunos de cerca de 1900 escolas que aderiram ao projeto entre 2006 e 2009, utilizando técnicas baseadas em escore de propensão e modelos multiníveis de regressão.
