In June 2008, the voters of San Francisco passed the Quality Teacher and Education Act (QTEA), which made changes to teacher compensation, support, and accountability. In collaboration with SFUSD, researchers have documented the passage of the policy and are engaged in a multi-year evaluation. The research questions for this study aim to uncover how QTEA is being implemented and how the policy affects the recruitment and retention of high quality teachers, the overall improvement of the teacher workforce, and the improvement or removal of less effective teachers.
