Out-of-school suspension is a key component of many school discipline policies, but is associated with adverse educational, justice, health, and welfare outcomes for excluded students. Exclusion at earlier grades and an over-representation of particular groups of disadvantaged students may intensify the inequalities of outcomes for suspended students. Previous studies have focused predominantly on secondary school exclusions and on sociodemographic predictors, with few investigations of suspension during primary school. This study aimed to identify early life predictors of primary school suspensions using multi-agency data from the New South Wales Child Development Study.
Linked data were available for 34,855 children and their parents, including the 2009 Australian Early Development Census, education, health, child protection, and criminal justice records. Multinomial logistic regression was used to examine associations between sociodemographic, pregnancy/birth, child, and parent factors (identified by the 2nd grade) and any suspension issued during 3rd to 6th grade.
In a fully adjusted model, 18 of 26 factors had significant independent associations with suspension. The strongest associations (odds ratios [ORs] ≥4.0) were observed for male gender, out-of-home care placement, and substantiated child maltreatment, with moderate or large associations (ORs 1.5 to <4.0) for unsubstantiated and subthreshold child protection notifications, aggressive behaviour, Indigenous status, socioeconomic disadvantage, exposure to smoking in utero, parental criminal offending, ≥2 emergency department presentations for physical injury, and problems in school-based responsibility and respect. Small associations (ORs >1.0 to <1.5) were identified for having an emotional/behavioural problem, poor language and cognitive skills (school-based), hyperactivity-inattention, young motherhood (<26 years), and parental mental illness. Lack of English proficiency reduced the risk of suspension.
Using multi-sector information available at the time of entry to school to facilitate the identification of students at risk of early exclusion may help educators and policy makers to deliver targeted preventative interventions.
