While almost any educator would agree that students deserve access to equal educational opportunities, many schools still sort students based on test scores or other criteria. There's a better way: one built on offering all students access to the best curriculum. In this first-ever practical book that shows how educators can make detracking work, two authors from a large metro district explain how heterogeneous grouping can foster high achievement and diminish racial and socioeconomic gaps. Based on what's worked in actual elementary, middle, and high schools, the book lays out a clear argument against tracking and provides you with proven strategies for launching, sustaining, and monitoring a successful detracking reform, including: (1) A backwards planning model for curriculum design; (2) Guidelines for lesson planning and classroom assessment; (3) Advice for confronting the resistance to detracking; (4) A multiyear, personalized professional development program that helps teachers address new instructional needs; and (5) Beliefs that sustain a detracked school over time.
