Evaluación del impacto del Programa de Escuelas de Tiempo Completo en medidas de logro académico de centros escolares en México.

In Mexico, until the reform to the article 51 of the General Law of Education enacted in 2016, the school calendar of the public schools of basic education determined that they had to comply with 800 hours of classes a year, as stipulated in the study plan and programs. With the aim of expanding learning opportunities, in 2008, the Full-Time Schools Program (FTSP) was established, which increased the total amount of classes to 1 200 hours devoted to teaching in the school year. This research sought to determine the impact of the implementation of the FTSP in the performance of students in the National Assessment of Educational Achievement in Schools. After controlling for sociodemographic covariates and attrition in response bias, the results show that the implementation of the program had a positive effect on the levels of achievement and test scores.
