Implementing Universal Social-Emotional Programs is a step-by-step guide for school-based mental health professionals seeking to effectively select, employ, and evaluate universal social-emotional programs using implementation science. With one out of five children having diagnosable mental health challenges and many more of our youth developing social-emotional concerns, today’s schools must be able to effectively plan and implement evidence-based programs that promote social-emotional learning and positive academic outcomes. This book accompanies practitioners and graduate students in teaching, school psychology, counseling, social work, education, and administration through each stage of implementation science, common programs and screeners, the purpose and selection process of implementation teams, and schools’ expectations for fidelity, timeline, and budget. Throughout, the authors provide graphic organizers, diagrams, activities, exercises, vignettes, checklists, templates, charts, and other interactive features for active engagement.
