Research and Evidence Base

Collaborative Classroom continuously learns and evolves alongside our district partners. For more than 40 years we have conducted research, analyzed data, and worked in classrooms to create and revise programs and services that support both students’ academic and social development and teachers’ ongoing professional learning.

We are committed to ongoing research on the efficacy of our programs and to the study of the effects of our programs on students’ literacy achievements.

Every Student Succeeds Act (ESSA)

The Every Student Succeeds Act (ESSA) replaced No Child Left Behind in December 2015. This federal education legislation emphasizes state and local control, providing school districts with the flexibility to determine appropriate curricula and interventions for their schools. The levels of evidence define the study criteria.
