What is the DESSA?

The Devereux Students Strengths Assessment (DESSA) is the assessment portion of Aperture Education’s Evo Social/Emotional Assessment and Intervention System. It is a standardized, strength-based measure of the social and emotional competencies of children in kindergarten through 8th grade. Grounded in resilience theory, the DESSA provides user-friendly, practical tools that meet the highest professional standards. With the DESSA, parents, teachers, and out-of-school-time staff can assess a child’s social and emotional skills and promote healthy outcomes.
