TNTP (formerly The New Teacher Project) is committed to ending educational inequities by promoting the recruitment, training, and retention of high-quality teachers and school leaders. The U.S. Department of Education's Supporting Effective Educator Development (SEED) grant has funded TNTP to implement the Teacher Effectiveness and Certification (TEACh) program in three regions. Through TEACh, TNTP works with organizational partners, such as school districts, to develop a local process to recruit, prepare, and certify teacher candidates, as well as support them with coaching and other training in their first year. The RAND Corporation conducted an evaluation of TEACh, investigating each program's implementation, the effects of TEACh on the recruitment and retention of teachers, and the relative performance of those teachers. These appendixes accompany the results of a study of the implementation and impact of the TEACh program established in partnerships between TNTP and three local partner organizations. The appendixes include: (1) Methods; and (2) Additional Impact Estimates. [For the main report, see ED616532.]
