This study used mixed-effects logistic regression to examine undergraduates' (N = 142) evaluations and reasoning about scenarios involving disability-based exclusion. Scenarios varied by disability [autism spectrum disorder (ASD) versus learning disability (LD)], the context of exclusion (classroom versus social), and whether or not a grade was at stake. Participants were more likely to determine exclusion was acceptable if the excluded student had an ASD diagnosis, there was a grade at stake, and it occurred in a classroom. Exclusion was less likely to be considered acceptable in the "no grade" compared to the "grade" conditions for LD students, but remained high in both conditions for autistic students. This study also describes contextual variations in participants' justifications for their evaluations.
