The DESSA Comprehensive SEL System

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




A Comprehensive, Cloud-Based System

The DESSA Comprehensive SEL System allows educators to measure, strengthen, and support social-emotional competence in youth K-12 grade. The DESSA System includes a suite of strength-based social emotional learning (SEL) assessments, a universal screener that can be administered in less than a minute, foundational practices, and growth strategies to strengthen social and emotional competence.  Actionable data and reporting helps SEL program administrators measure the impact of their programs and helps educators understand students’ SEL strengths and needs.

Tools to Understand and Act Upon

Along with the DESSA, DESSA-HSE, and DESSA-mini (a shorter, but still reliable 8-question screener), DESSA System users have access to research-informed Growth 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. In addition, each competency comes with a teacher reflection activity – allowing users to understand their own social and emotional strengths and areas of need.
