BackgroundChildren's educational experiences worldwide have been significantly impacted as a result of global school closures during the COVID‐19 pandemic of Spring 2020. A growing number of studies aim to analyse impacts of these changes on social well‐being, with limited studies placing an emphasis on the experiences of students with special educational needs (SENs). This article focusses on parent perspectives regarding impacts of school closures on social well‐being in Canadian children with SEN.MethodsThis study uses a mixed‐methods approach, drawing from both qualitative and quantitative survey data from Spring/Summer 2020. Participants (n = 263) were eligible for participation if they were a parent/guardian of a child or adolescent with an SEN. We first conducted a descriptive analysis of the key variables, namely, social well‐being, grade level of the child, internet and device availability, and the presence of other school‐aged children in the home (single child vs. multiple children). Next, we explored the relationship between these using a bivariate correlation. Finally, open‐ended responses were analysed using an inductive approach to qualitative thematic analysis.ResultsThe majority of parents expressed concern for their child's social well‐being during the Spring 2020 school closures, with increased concerns for younger children. According to parents, children experienced communication barriers to peer interaction and many experienced emotional difficulties as a result. Technology was described as critical for some in maintaining social connections. Parents raised concerns about the impact of limited peer interaction on broader social skill development, in the short and long term. A small number of participants noted feelings of relief and reduced anxiety among their children with SEN.ConclusionsFindings highlight parent views of the negative impact of the pandemic on social well‐being and the critical role in‐person schooling plays in supporting peer relationships for children with SEN.
