This report focused on the first year of findings only. The research team is conducting longer term followup to include additional collection of test score and teacher mobility data. In addition, the intervention was expanded to include a second year of services for treatment teachers in seven of the districts (4 ETS and 3 NTC), selected based on districts’ willingness and ability to continue the program. Future reports will therefore provide evidence on the longer-term effects of both a one-year program in 10 districts and a two-year program in 7 districts.
