In 2012, researchers began a randomized control trial (RCT) study to evaluate the impact of the WINGS Afterschool SEL program on the at-risk students it serves. Led by Dr. David Grissmer at the University of Virginia and funded by the Institute of Education Sciences and the Edna McConnell Clark Foundation, the RCT studied three cohorts of students entering kindergarten at four elementary school-based WINGS programs in Charleston, SC, over a four-year period. To date, it is the only such study on the impact of SEL in an afterschool setting. (author abstract)
