Massachusetts is heralded nationally for being the first in the nation to enact a state policy to redesign and expand the learning day for all students to advance academic achievement, broaden enrichment opportunities, and improve instruction. The Expanded Learning Time (ELT) Initiative has gained momentum over the past several years due to the strong advocacy and leadership of Governor Deval Patrick, Massachusetts Secretary of Education Paul Reville, and the Massachusetts Legislature, especially the chairpersons of the Education Committee, Representative Marty Walz and Senator Rob O'Leary. While many important education programs in the state have been impacted by dwindling state coffers, the state leadership's continued commitment and support of this innovative program has been critical to its ongoing success. Today, the 22 ELT schools serving over 12,200 students across the state are models to the Commonwealth and the entire country for how schools can be transformed when teachers, administrators, parents, and the community work together to add learning time and broaden what schools should offer. As the national momentum for expanded learning time continues to build, the Massachusetts ELT Initiative continues to be recognized for its promising results for students, teachers, and schools. This paper presents the Massachusetts ELT Initiative progress report for 2010. It discusses the lessons the founders have learned over the past four years of working with ELT schools--such as how some successful schools are using additional academic time to individualize academic supports to better meet student needs--and how they are refining their model to produce even greater student success.
