From 2000 to 2011, the number of children out of school worldwide has decreased from 102 million to 57 million--a reduction of almost 50 percent (Millennium Development Goals Report, 2013). However, many children in developing countries do not complete primary or secondary cycles once they enroll; out of the 137 million children who entered first grade in 2011, 34 million are likely to leave school before reaching the last grade in primary school (Millennium Development Goals Report, 2013). Unfortunately, the research base into interventions targeting student dropout in developing countries is still underdeveloped. The School Dropout Prevention Pilot (SDPP), a five-year, multi-country program, funded by the U.S. Agency for International Development, is designed to help fill this research gap by piloting and evaluating interventions aimed at decreasing student dropout rates in primary and secondary schools in Cambodia, India, Tajikistan, and Timor-Leste. Each intervention consists of an Early Warning System (EWS), which uses student data to identify and provide additional support students who are most likely to drop out of school, and additional country-specific school activities. The impact evaluations address the following questions: (1) Do the interventions improve the dropout rate? (2) Do the interventions improve student engagement in school? (3) Do the interventions improve student behavioral and attitudinal outcomes? (4) Do the interventions improve teacher behavior and attitudes? and (5) What are the programs' impacts on all of the above dimensions for students identified as being at risk of dropping out of school? In this presentation, the authors present impacts from the first follow-up data collection, which represents less than a complete school year of exposure to the interventions. They will conduct two rounds of additional data collection in the remaining two years of the program. Two tables are appended.
