Individualized Classroom Assessment Scoring System (inCLASS) Project


Assessing Preschoolers' Classroom Behavior

inCLASS logo.jpgThe Individualized Classroom Assessment Scoring System™ (inCLASS) is an observational assessment of young children's competence during everyday interactions with teachers, peers, and tasks in preschool and kindergarten classroom environments.

Initial findings from research in over 300 classrooms indicate promising psychometric properties, including interrater reliability as well as construct and criterion-related validity. A number of inCLASS on-line resources are currently in development for early childhood teachers, including: a) a video library with over 200 exemplar videos of child behaviors, and b) a set of training modules designed to help teachers learn more about and improve detection of key interactions within their classrooms.

The inCLASS is part of the Interagency Consortium for School Readiness Outcome Measures (ICSROM) and co-funded by the U.S. Departments of Health and Human Services and Education.
