This paper presents and assesses the effects of an Extended School Time project (ESTp), with a working day of 8 contact hours, that aimed to develop the students as a whole in its academic, artistic, sport, social and human dimensions. Based in active and integrated pedagogical practices, the project promoted the integration of knowledges,…

The current study evaluates effects of teaching factors and extended day programs regarding both average achievement and socioeconomic achievement gaps. Analyses are based on data from the National Educational Panel Study in Germany. The sample comprises 1523 students in 120 classes in 71 secondary schools. The investigation period covers fifth…

Expanded Learning Time (ELT) measures have been implemented internationally to reduce the likelihood of academic underachievement among students at risk. The goal of this article is to examine the components of an ELT initiative aimed at supporting students at risk of academic failure in order to optimize the components that can improve its use…

This paper evaluates the impact of extension of the school day in the context of Brazil's "Mais Educação" Extended School Day Program. Using school level longitudinal data, we find that the program reduces the dropout rates of students in all grade levels, raises the enrollment of students in grades 6-9, but reduces the enrollment of…

Instructional time is a fundamental educational input, yet we have little causal evidence about the effect of longer school days on student achievement. This paper uses a sharp regression discontinuity design to estimate the effects of lengthening the school day for low-performing schools in Florida by exploiting an administrative cutoff for…

Expanded learning time (ELT) refers to a longer school day, week, or year. ELT schools are becoming common in the United States and aim to provide all students with additional opportunities for learning, recreation, and enrichment. ELT schools differ from afterschool programs that take place immediately following the regular school day and serve a…

Increasing the number of hours students spend in school each year, on the assumption that this will improve student achievement, has become a widespread trend. However, the analysis reported here suggests that this trend can be misguided: the time students spend in the classroom is not always positively related to their academic achievement.…

Schools frequently increase the instructional time to improve primary school children's math and reading skills. There is, however, little evidence that math and reading skills are effectively improved by these instruction-time increases. This study evaluates "Playing for Success" (PfS), an extended school day program for underachieving…

This brief highlights key information about enrichment activities, which represent one of the main components of the Massachusetts Expanded Learning Time (ELT) initiative. Over time, the ELT initiative has supported over two dozen schools across the Commonwealth. A comprehensive evaluation of the ELT initiative found that implementation of the…

The Massachusetts Expanded Learning Time (ELT) initiative was established in 2005 with planning grants that allowed a limited number of schools to explore a redesign of their respective schedules and add time to their day or year. Participating schools are required to expand learning time by at least 300 hours per academic year to improve student…

Expanded learning time seems to be a simple idea: by lengthening the school day (or year), students have more time to learn. Yet as schools revisit their schedules and decide how to allocate time in their academic calendars, they can and do face challenging decisions related to time allocations. This brief highlights lessons learned from some…
