What is the DESSA?

The Devereux Students Strengths Assessment (DESSA), originally developed by the Devereux Center for Resilient Children, 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.

Why Should I Use the DESSA?

Research-Based: The DESSA is both nationally standardized and norm-referenced, with a standardization sample of n=2494. In addition, it exceeds the recommended standard for rater reliability and assessment validity. For more specific information, visit our DESSA 101 page.

Progress Monitoring: In addition to the full, 72-item DESSA, the DESSA-mini (a shorter, 8-item assessment) can be used to monitor your students’ social and emotional development throughout the school year, providing actionable data to steer quality SEL intervention.

CASEL Aligned: Aperture Education’s 8 social and emotional learning (SEL) competencies are directly aligned to the Collaborative for Academic, Social and Emotional Learning’s (CASEL) highly-regarded five SEL competency framework.

Multi-lingual: The DESSA and DESSA-mini are provided in both English and Spanish, serving all raters – including families – who may not speak English as a first language.

Personalized Use: Along with access to the DESSA and DESSA-mini, users also have access to the full suite of intervention strategies and foundational practices, as well as 24/7 system support and a team of dedicated implementation personnel. This ensures that each users experience is efficient, yet personalized.
