Qualitative differences in learning disabilities across postsecondary institutions.

Many college students receiving accommodations for specific learning disability (SLD) do not meet objective criteria for the disorder. Furthermore, whether students meet criteria depends on the diagnostic decision model used by their clinician. The authors examined whether the relationship between diagnostic model and likelihood of meeting objective criteria is moderated by students' postsecondary institution. They administered a comprehensive psychoeducational battery to 98 undergraduates receiving accommodations for SLD at 2-year public colleges, 4-year public universities, and 4-year private colleges. Most 4-year public university students failed to meet objective criteria for SLD. In contrast, most 4-year private college students met objective criteria based on significant ability-achievement discrepancies, and most 2-year public college students met objective criteria based on normative deficits in achievement and cognitive processing. Students who met objective criteria also differed significantly in degree of academic impairment. The authors' findings indicate qualitative differences in SLD across postsecondary settings and have implications for the identification and mitigation of SLD in college students.
