What can we do to reduce disciplinary school exclusion? A systematic review and meta-analysis

Abstract

Objectives: To systematically review and quantitatively synthesise the evidence for the impact of different types of school-based interventions on the reduction of school exclusion. Methods: A systematic search of 27 databases including published and unpublished literature was carried out between September and December 2015. Eligible studies evaluated interventions intended to reduce the rates of exclusion, targeted children from ages four to 18 in mainstream schools, and reported results of interventions delivered from 1980 onwards. Only randomised controlled trials were included. Two independent reviewers determined study eligibility, extracted data, and rated the methodological quality of studies. Results: Based on the 37 studies eligible for meta-analysis, under a random effects model, results showed that school-based interventions significantly reduced school exclusion during the first 6 months after implementation SMD =.30, 95% CI [.20,.41], p
