This study is a program evaluation or open-trial study of the effectiveness of Summer Academy, a comprehensive summer early intervention program for young children with early learning and disruptive behavior problems (based on the nationally recognized, evidence-based Children's Summer Treatment Program) living in at-risk community settings. The summer program, which is funded by The Children's Trust, will be held annually from June to August from Summer 2016 - Summer 2019 at an early childhood center located in the Liberty City community of Miami, FL. Our aims are to evaluate how well the program helps to prepare young children for the transition to kindergarten and measure to how well progress is maintained at six-month follow-up.
