Which children and young people are excluded from school? Findings from the Avon Longitudinal Study of Parents and Children (ALSPAC)

Abstract

BackgroundSchool exclusion is a disciplinary method used to remove a child from the school environment. It is known to affect certain groups disproportionately, including boys, some ethnic minorities, children in care, children in poverty, and children with special educational needs. Population-based studies on wider characteristics of excluded pupils are scarce. The aim of this study was to describe factors associated with school exclusion in the Avon Longitudinal Study of Parents and Children (ALSPAC), focussing on neurodevelopment and mental health. MethodsALSPAC is a prospective population-based British birth cohort study, with the initial sample consisting of 14 541 pregnancies. The study has data for whether a child has been permanently excluded from school up to the age of 8 years as reported by parents and also permanent and fixed period exclusions in the preceding 12 months as reported by parents and young people at age 16 years. Upstream risk factors were assessed for associations with exclusion on univariable analysis. The association with social communication difficulties was investigated with multivariable logistic regression. FindingsData for exclusions up to the age of 8 years were available for 8245 ALSPAC participants and 4482 participants for exclusion at age 16 years. 53 pupils (0·6%) were excluded from school by age 8 years, and 390 (8·7%) at age 16 years. The odds of exclusion by 8 years and at 16 years were increased with male sex (p=0·001 and p<0·0001, respectively), low family income (p=0·014 and p<0·0001), family adversity (p<0·0001 for both), maternal psychopathology (p=0·013 and p=0·004), low intelligence quotient (p=0·041 and p<0·0001), mental health difficulties (p<0·0001 for both), psychiatric disorder (p<0·0001 for both), social communication difficulties (p<0·0001 for both), antisocial activities (p=0·004 and p<0·0001), bullying or being bullied (p=0·005 and p<0·0001), low educational attainment (p<0·0001 for both), and increased special educational needs (p<0·0001 for both). On multivariable analysis, having social communication difficulties above a clinical threshold on the Social Communication Disorders Checklist was strongly associated with exclusion by 8 years (odds ratio 7·4, 95% CI 3·6–15·4) and at 16 years (2·3, 1·5–3·5), after adjustment for relevant confounders. InterpretationAlthough cohort attrition and small numbers of exclusions at 8 years are limitations, this study suggests that school exclusion is associated with numerous risk factors identifiable at or before primary school entry. Child health professionals have an important role in the holistic assessment of children who are excluded, or who are at risk of school exclusion. There is particular need to ensure that mental health and neurodevelopmental difficulties are appropriately recognised and supported.
