To reduce the achievement gap, schools can implement innovative schedules aimed at improving student learning; the use of time is a valuable but often untapped resource. Innovative schedules include but are not limited to extended-year, extended-week, and extended-day programs. Often, alternative schedules do not add hours to the school day but can improve the quality of the time that students and their teachers spend at school. A well-crafted schedule can result in a more effective use of space, time, and resources; aid in establishing desired programs and instructional practices; allow teachers the chance to collaborate; and enhance the overall school climate.
