Evo Social/Emotional

Aperture Education’s social and emotional learning system – including the nationally recognized Devereux Student Strengths Assessment (DESSA) and DESSA-mini.

A Comprehensive, Cloud-Based System

Evo Social/Emotional (Evo SEL) is a comprehensive, cloud-based system used to assess, inform and improve the social and emotional skills of children both in-school and out-of-school. Evo SEL features the Devereux Student Strengths Assessment (DESSA), an empirical, standardized and strength-based assessment that provides reliable data on the strengths of students’ social and emotional skills, as well as areas where students may need additional instruction.









Reliable, Evidence-Based Assessment

With over twelve years of research behind it, the DESSA is one of the most reliable tools to assess social and emotional skills. Paired with the award-winning technology available within Evo Social/Emotional, this system offers reliable and user-friendly data that schools and out-of-school-time programs can count on.

Tools to Understand and Act Upon

Along with the DESSA, DESSA-Second Step Edition (SSE), and DESSA-mini (a shorter, but still reliable 8-question screener), Evo SEL users have access to research-informed Intervention Strategies and Foundational Practices, used to bolster social and emotional skills on eight SEL competencies. These strategies can be used universally (large group settings, like a classroom), in small groups, individually, or as take-home assignments.
