Too many students in Chicago Public Schools are performing below -- often far below -- grade level. Ideally, all students should be increasing their subject matter knowledge and critical thinking skills over time. In September 2008 a three-year initiative, the Partnership for Instructional Leadership, was created to help a group of neighborhood elementary schools in Chicago Public Schools Area 4, on the city's Northwest Side, build the internal capacity to improve school achievement for all students at all grade levels, including Pre-K and English Language Learners.**Over the course of three years, the Partnership was implemented in 11 elementary schools -- six for the full three years with five more schools joining in the third year. This report summarized significant outcomes and learnings from the Partnership experience.
