London Education and Inclusion Project (LEIP): Results from a Cluster-Randomized Controlled Trial of an Intervention to Reduce School Exclusion and Antisocial Behavior.

School exclusion as a disciplinary measure remains a controversial issue. In spite of numerous attempts to reduce this practice, no solutions with documented effectiveness exist. This article reports results of a cluster-randomized controlled field trial carried out in 36 schools across London. The trial is an independent evaluation of a 12-week-long intervention, Engage in Education-London (EiE-L), delivered by Catch22. The intervention was aimed at students in secondary school who are most at risk of school exclusion. It targeted their social communication and broader social skills with the aim of reducing school exclusions and problem behaviors. The study employed a multi-informant design that included students and teacher reports as well as official records for exclusions and arrests. Data were analyzed through intent-to-treat analyses based on self-reports from 644 students and 685 teacher reports for students who were nominated for the study and for whom data was available at baseline or post-intervention. At baseline data collection the students ranged in age from 12.85 to 15.03, with M = 14.03; 71 % were male and included a number of ethnic minorities, the largest of which was black African/black Caribbean comprising 40 % of the sample. The results suggested a small but statistically significant negative effect on the primary outcome of exclusion and null effects for the secondary outcomes that measured behavioral and socio-emotional outcomes. The study's findings are discussed in terms of the possible reasons for the null effects and negative (iatrogenic) effect.

London Education and Inclusion Project (LEIP): Exploring Negative and Null Effects of a Cluster-Randomised School-Intervention to Reduce School Exclusion--Findings from Protocol-Based Subgroup Analyses.

UNLABELLED: This paper presents subgroup analyses from the London Education and Inclusion Project (LEIP). LEIP was a cluster-randomised controlled trial of an intervention called Engage in Education-London (EiE-L) which aimed to reduce school exclusions in those at greatest risk of exclusion. Pupils in the control schools attended an hour-long employability seminar. Minimisation was used to randomly assign schools to treatment and control following baseline data collection. The study involved 36 schools (17 in treatment--373 pupils; 19 in control--369 pupils) with >28% free school meal eligibility across London and utilised on pupil self-reports, teacher reports as well as official records to assess the effectiveness of EiE-L. Due to multiple data sources, sample sizes varied according to analysis. Analyses of pre-specified subgroups revealed null and negative effects on school exclusion following the intervention. Our findings suggest that the design and implementation of EiE-L may have contributed to the negative outcomes for pupils in the treatment schools when compared to those in the control schools. These findings call into question the effectiveness of bolt-on short-term interventions with pupils, particularly those at the highest risk of school exclusion and when they are faced with multiple problems. This is especially pertinent given the possibility of negative outcomes. TRIAL REGISTRATION: Controlled Trials: ISRCTN23244695.
