The goal of the Intensive Partnership (IP) initiative is to improve student success by transforming how teachers are recruited, developed, assigned, rewarded, and retained. RAND and American Institutes for Research (AIR) have been studying the seven IP sites (including three districts and four charter management organizations--CMOs) since the 2010-11 school year to understand which strategies for improving the teaching workforce are successful. This report summarizes key findings about how school leaders and teachers have changed the way they allocate their time among various activities across the three years since implementation began (2010-11 through 2012-13). The report contains a preface, acknowledgements, and an executive summary and then presents the findings in five parts. They are: Part I: Introduction; Part II: Methodology; Part III: School Leader Time Allocation Findings; Part IV: Teacher Time Allocation Findings; and Part V: Summary and Concluding Thoughts. The report also includes the appendices: (1) Detailed Discussion of Methodology; (2) School Leader and Teacher Survey Response Rates; (3) Descriptive Statistics of Individual and School Characteristic Categories by Site and Year; (4) School Leader Time Allocation by Site; (5) Teacher Time Allocation by Site; (6) Survey Questions and Categories; (7) Analysis of Individual Questions for Selected Categories for School Leaders; and (8) Analysis of Individual Questions for Selected Categories for Teachers.
