Recent research in implementation science has focused on identifying factors that predict adoption of evidence-based practices in schools. Less attention has focused on examining the adoption of practices within districts. This study included a sequential cohort of 552 districts in 25 U.S. states adopting an evidence-based framework, school-wide…

Scholarship and policy emphasize strengthening the early childhood education (ECE) workforce, but this work neglects a large segment of the workforce: assistant teachers. The present study responds to gaps in knowledge by examining the demographic characteristics, qualifications, professional supports, and workplace experiences of assistant…

Background: In this paper we call for studying school leadership and its relationship to instruction and learning through approaches that highlight the role of configurations of multiple organizational supports.

We report here on our experiences in recruiting participants…

Randomized experiments are often considered the strongest designs to study the impact of educational interventions. Perhaps the most prevalent class of designs used in large scale education experiments is the cluster randomized design in which entire schools are assigned to treatments. In cluster randomized trials (CRTs) that assign schools to…
