Released on September 15, 2011, Harnessing the Power of Expanded Time to Improve Schools: A Study of Three Districts seeks to answer this question. In this report, NCTL documents the work of three urban districts – Buffalo, NY; Pittsburgh, PA; and Volusia County, FL (Dayton Beach area) – to comprehensively transform a group of persistently low-performing schools over several years. In each of the districts, schools were afforded more time in the daily schedule for individualized academic support for students, collaborative teacher planning, and embedded professional development.W:ith the Obama Administration and Congress focused on turning around schools in the nation’s neediest communities, these case studies offer meaningful lessons to the field on the potential for high-quality expanded learning time as a powerful tool for reform.
