This report contains the results of the 2009-10, 2010-11, and 2011-12 Principal and Assistant Principal (AP) Surveys conducted by Stanford's Center for Education Policy Analysis (CEPA). The surveys were administered to principals and assistant principals in the San Francisco Unified School District (SFUSD). This report appears in three parts, each highlighting some of the aggregated responses from the principals and assistant principals. More than one-half of principals were likely to remain a principal until they retire, work in education but outside of k-12 schools, or work in the district office. Over 60 percent of APs indicated they were likely to become a school principal in their future career. Other noticeable career choices include working in education but outside of k-12 schools and staying in education but not in SFUSD.
