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…

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…

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 study looks at the question of whether charter schools are more innovative in their provision of extended time policies than a matched set of traditional public schools. Data for this study was collected from a sample of traditional public and charter schools that partner with the Northwest Evaluation Association (NWEA) for interim…

The Cape York Aboriginal Australian Academy (CYAAA), which began operation as part of the government schooling system in 2010, incorporates activities across three overlapping "domains": Class--the formal schooling component; Culture--Indigenous and non-Indigenous cultural knowledge; and Club--sporting, cultural, music and physical…

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…

In this article, Ardice Hartry, Robert Fitzgerald, and Kristie Porter present results from their implementation study of a structured reading program for fourth, fifth, and sixth graders in an afterschool setting. As the authors explain, schools and districts often view an extended school day as a promising way to address the literacy needs of…
