"A case study of Sports4Kids by the Harvard Family Research Project found that Sports4Kids’ recess and other programs saw visible improvement in several key areas of youth development.During the 2011 summer, Playworks displayed a 15-second digital ad in New York City’s Times Square, announcing “Recess is another word for the recommended daily allowance of Play.”

Research by the Department of Pediatrics at the University of California, San Francisco compared physical and emotional health outcomes between students in schools that participated Playworks, and a control group.
