Population-level gender-based analysis of the educational journeys of students with autism spectrum disorder in British Columbia, Canada

Research examining the impact of gender on educational outcomes in autistic students has been sparse. To address this gap, this study investigated the educational journeys of students with autism spectrum disorder in British Columbia, Canada. We examined (1) the time it takes for students to receive an initial autism spectrum disorder designation; and the frequency and percentage of students who (2) stay longitudinally in the Kindergarten-to-Grade 12 school system; (3) complete high school and the credential earned; and (4) proceed to public post-secondary education within British Columbia. We conducted secondary analyses of administrative data. The autism spectrum disorder student population was divided into eight longitudinal cohorts with a combined final sample size of 4282 students with autism spectrum disorder: 738 female (17.2%) and 3544 (82.8%) male. Descriptive analyses indicated statistically significant gender differences in students' time to initial autism spectrum disorder designation, rates of high school completion and the specific high school credential earned. No gender differences were found in post-secondary transition rates. During their formative education years, gender differences, particularly the delay in autism spectrum disorder diagnosis among girls, may have implications with respect to educational outcomes. Results emphasize the need to provide educators with greater information about recognizing gender differences in autism spectrum disorder.Lay Abstract<u>a. What is already known about the topic?</u>Over the past several years, there is growing acknowledgement of gender inequities among people with autism spectrum disorder. The inequity is evidenced, in part, by gender differences in diagnosis. Although the gender gap is narrowing, until recently the diagnostic criteria for autism spectrum disorder has largely favoured and is more sensitive to detecting autism spectrum disorder in boys.<u>b. What does this paper add?</u>Research examining the impact of gender on educational outcomes in autistic students has been sparse. To address this gap in the literature, the current study investigated the educational journeys of students with autism spectrum disorder in British Columbia, Canada.We found statistically significant gender differences in students' time to initial autism spectrum disorder designation, rates of high school completion and the specific high school credential earned. There were, however, no significant differences in whether or not students stayed longitudinally in the K-12 school system over time, whether students transitioned into post-secondary or not (non-developmental or developmental), nor in students' transition times into the respective post-secondary education programmes.This study highlights the value of longitudinal, population-based and student-level data in conducting gender-based analyses in autism spectrum disorder research.<u>c. Implications for practice, research or policy</u>Understanding how gender impacts the academic trajectories of students with autism spectrum disorder over time can inform the development of tailored interventions and services which address their unique needs. Ultimately, this research is needed to promote more equitable educational experiences and outcomes.
