Measuring SEL competencies

An SEL Program with Actionable, Accurate Data

Along with the powerful data from the suite of SEL assessments, the DESSA System software provides users with access to research-informed social emotional learning activities, including Growth Strategies and Foundational Practices, used to bolster social and emotional skills on eight SEL competencies.

These social and emotional learning activities 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.
