Research has indicated that educational diagnoses can differ from clinical diagnoses of autism spectrum disorder (ASD). This brief report provides an updated analysis using 2014--2015 IDEIA data compared to the contemporary CDC prevalence rate (1 in 59). Additionally, the variable of sex was analysed, which was omitted from the previous study. Results show a greater discrepancy in educational diagnoses for girls versus boys as compared to the clinical diagnoses. For race/ethnicity, only Asian American children were more likely to have an educational diagnosis versus a clinical diagnosis of ASD.
