More schools than ever are expanding their schedules beyond the traditional limits of six and a half hours a day, 180 days of the year. Schools serving predominantly high-poverty populations make up the vast majority of this emerging movement as they try to overcome the widespread failure of schooling to meet academic goals for high-risk students. Although raising academic achievement is certainly the single biggest driver of this wave, many participants are also motivated by the desire to provide a well-rounded education to all children and to address their broader social-emotional and twenty-first century skills needs. This chapter offers an overview of expanded learning time (ELT) schools and their relationships with community-based partners offering expanded learning opportunities (ELOs). (Contains 17 notes.)
