Funded by the Administration for Children and Families (ACF) in DHHS, this project involved designing and implementing an evaluation of classroom-based strategies to improve children’s social-emotional competencies. The study randomly assigned 120 Head Start centers to either a social-emotional program group or a “business as usual” control group. MEF Associates was a subcontractor to MDRC. Mike Fishman co-lead the site recruitment team and the implementation evaluation team. He also led a Migrant and Seasonal Head Start sub-study.
