A strength-based, nationally standardized, valid and reliable tool for screening and progress monitoring of social and emotional competence that can be completed in under 1 MINUTE.

Screen in 1 Minute

The DESSA-mini enables teachers and staff to screen an entire classroom or group of students in one planning period (less than 45 minutes).

Monitor Progress

Consisting of four different, yet equivalent, 8-item forms, the DESSA-mini provides a simple and effective way to track changes in social and emotional competence over time.

Preventive Measures

In a recent study, students in the Need for Instruction range on the DESSA-mini at the beginning of the school year were


to commit a serious behavioral infraction by the end of that school year, compared to their peers. The DESSA-mini can help identify students with a Need for Instruction and intervene before challenging behaviors occur, using only 8 strength-based items.
