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 core ELT components varied considerably across schools. This brief focuses on enrichment activities provided for students, drawing primarily from surveys of teachers, surveys of 5th and 8th grade students, as well as interviews with principals, in 17 ELT and 19 matched comparison schools that participated in the ELT evaluation during the 2010-2011 school year. Over the course of the ELT initiative, the study found that teachers had increasingly positive views about the value of enrichment. The majority of teachers at ELT schools reported that enrichment opportunities were valuable to students, well integrated into the school day, and of high quality. Most teachers also reported that enrichment was clearly connected to curriculum frameworks or standards. Almost all students at ELT schools were able to participate in at least some enrichment, regardless of academic standing. Enrichment also offered schools the opportunity to develop community partnerships and offered students choice about a portion of their schedules.
