This companion to "Safe and Sound: An Educational Leader's Guide to Evidence-Based Social and Emotional Learning (SEL) Programs" provides information on each of the 80 programs in the review. The information is intended to give schools and individuals a better overall understanding of each program. The description includes the program's design and aims, its notable strengths and SEL coverage, evaluation results, professional development opportunities, and contact information. Most of the program aspects presented are narrative explanations of ratings that programs received in the Program Ratings Table. These descriptions were written by CASEL, not the program developers, and in most cases were based on information in the program materials. Training and cost information was collected via mail and phone surveys of program developers. (GCP)
