This document outlines interventions used at Belleville Township High School East to close achievement gaps. It discusses who the school serves, assessments used, and strategies in three areas: what to teach, how to know if students learned, and what to do if they did not learn. Strategies include curriculum and test prep programs, targeted assistance courses, mentoring, co-teaching, and instructional teams. Assessment results show increases in the percentage of students meeting or exceeding standards from 2003 to 2006.
