The ACT Matrix is a visual representation of the cognitive-behavioral approach to values-based behaviors known as Acceptance and Commitment Therapy (ACT). It quickly engages people in a process that builds psychological flexibility, which is a cornerstone of good mental health. This evidence-based, mindful approach “loosens up” stuck and struggling learners by empowering them to move toward resilience and persistence in the face of obstacles and challenges. This guide shows educators, school psychologists, and other school staff how to use the ACT Matrix to walk students through a process of identifying values, regulating emotionally challenging experiences, and achieving greater satisfaction and success academically and socially. It can be used at all grade levels (K-12) for developing social-emotional skills such as self-awareness, self-monitoring, self-regulation, social awareness, and goal-directed behavior; establishing a positive classroom and school climate and culture of caring, respect, and personal responsibility; increasing engagement and on-task behavior; positive behavior support and intervention; strengthening classroom management; improving problem-solving skills and student achievement; promoting effective collaboration; establishing a shared point of view and language that fosters cooperation among students, staff, and administration.
