Schoolwide positive behavior interventions and supports (SWPBIS) is currently implemented in more than 23,000 schools nationally and internationally. Several reviews have examined the SWPBIS evidence base, including a meta-analysis of single-case design research. However, to date, there has not been a review of group-based experimental research…

Social-emotional learning (SEL) programs are frequently evaluated using randomized controlled trial (RCT) methodology as a means to assess program impacts. What is often missing in RCT studies is a robust parallel investigation of the multi-level implementation of the program. The field of implementation science bridges the gap between the RCT…

There are several widely used Positive Behavioral Interventions and Supports (PBIS) implementation fidelity measures, including the Schoolwide Evaluation Tool (SET), but there is limited empirical investigation substantiating the association between specific fidelity cut point scores and student outcomes. This article examined different SET cut…

Disruptive behavior problems frequently emerge in the preschool years and are associated with numerous, long-term negative outcomes, including comorbid disorders. First Step is a psychosocial early intervention with substantial empirical evidence supporting its efficacy among young children (Walker et al., 2014). The present study reports on a…

This article addresses issues related to whether null randomised control trial (RCT) findings can by themselves be a secure indicator of programme failure. This is done by drawing on the findings of the evaluation of the Integrated Group Reading (IGR) programme using a number of teacher case studies. The case studies illustrate how the same…

Most community college students are referred to developmental education courses to build basic skills. These students often struggle in these courses and college more broadly. CUNY Start is a prematriculation program for students assessed as having significant remedial needs. CUNY Start students delay matriculation for one semester and receive…

As the number of publicly funded early childhood education (ECE) programs increases, policymakers will need empirical evidence to justify the taxpayer investment. Such justification will require a stronger understanding of the essential components of an ECE program's design, as well as solid evidence on which components, or constellations of…

This report presents findings from exploratory, descriptive meta-analyses of effect sizes reported by the first 82 EEF evaluations that used a randomised controlled trial (RCT) or clustered RCT impact evaluation design published up to January 2019. The review used a theoretical framework derived from literature with five overarching themes to…

This document summarises key findings from the quantitative strands of a review of the Education Endowment Foundation (EEF) evaluations that had reported from the establishment of EEF in 2011 up to January 2019. The quantitative strands summarised include meta-analyses of effect sizes reported for attainment outcomes and descriptive analyses of…

This document provides supplementary statistical tables to support the review of Education Endowment Foundation (EEF) evaluations. This includes: (1) Descriptive (univariate) tables for all explanatory variables; (2) Tables for the meta-analyses of primary ITT effect sizes; (3) Tables for the meta-analyses of secondary ITT effect sizes; (4) Tables…

Strain provides his perspective on four issues facing science and practice in early childhood and special education. He points to the need for (a) long-term functional research, (b) greater emphasis on the use of evidence-based programs in practice, (c) moving special education research back to the Office of Special Education Programs, and (d)…

The present study sought the views of stakeholders, including school leaders and statutory stakeholders, on the content and evaluation of a classroom-based alcohol education intervention in a Randomised Controlled Trial in Scotland and Northern Ireland. Purposive sampling was used to ensure that schools from both the Intervention and Control…

The purpose of this study was to examine the effects of a school-wide attendance and truancy intervention and universal procedures (ATI-UP) on student attendance. Student attendance was measured through average daily attendance and the percentage of students who would be considered chronically absent, i.e., missing 10% or more of school. The…

Despite the knowledge that quality early childhood development programs, including those that target parental knowledge and behaviors, are essential for ameliorating the negative effects of early-life adversity, robust analyses of their implementation and impact in highly vulnerable settings are scarce. To address this knowledge gap, we conducted…
