To examine key outcomes in the education of young people with and without neurodisabilities, and to investigate additional disparities in educational achievement in relation to socio-economic background. Data were collected on 2488 Canadian children (age range 10-11y) in 1994 and 1995 from the National Longitudinal Survey of Children and Youth whom were followed for 14 years. We performed separate, discrete-time survival analysis to investigate the effects of having a neurodisability on high school completion, enrolment in post-secondary education (PSE), and PSE completion. The baseline prevalence of neurodisabilities was 12%. Fewer children with neurodisabilities completed high school or enrolled in PSE, compared to children without neurodisabilities, irrespective of parental education. The likelihood that students with neurodisabilities completed PSE differed according to their parents' education: students with neurodisabilities living in less-educated families were about half as likely to complete PSE themselves. Children with neurodisabilities receive less education than children without neurodisabilities. Children from families with low educational attainment appear to be particularly vulnerable. Twelve per cent of children in Canada aged 10 years to 11 years have a neurodisability. High school completion rate was 70% for children with neurodisabilities versus 94% for children without neurodisabilities. Children with neurodisabilities from less-educated families are particularly vulnerable to lower educational achievement.
