In the winter of 2006-2007, The New Teacher Project (TNTP) engaged in an extensive review of teacher staffing policies and practices in Chicago Public Schools (CPS). TNTP investigated the impact of CPS staffing rules through several avenues: (1) Review of CPS Teachers contract; (2) Analysis of Human Resources transaction data; (3) Surveys of principals, current teachers, and teacher applicants; and (4) Interviews with principals and central staff. Feedback from principals, teachers, and applicants, along with Human Resources data has made clear to TNTP that Chicago has many sound human capital policies and practices already in place and has made significant progress in recent years. Nonetheless, TNTP has identified a number of staffing processes that can be improved to better serve all schools, teachers and students.
