The authors survey the current afterschool landscape and bring to light important issues and practices within the field, explore the challenges and opportunities facing afterschool education programs, and point to future directions for these burgeoning educational ventures. Afterschool education has grown in recent years into a vast and diverse enterprise. In the United States, young people spend almost a third of their organized time (including school hours) in afterschool and summer programs. Yet there is little clear and conclusive research on afterschool programs—research that would help guide the practice of existing afterschool programs and establish guidelines for the creation of new programs. An indispensable guide for practitioners, administrators, policy makers, and parents, Afterschool Education will serve as the cornerstone for all future accounts of and proposals for this crucial educational field.
