Evo Social/Emotional

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



What is the Evo Social/Emotional Assessment and Intervention System?

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.









Tools to Understand and Act Upon

Along with the DESSA 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, in small groups, individually, or as take-home assignments.

Reliable, Valid and Nationally-Normed

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.
