The purpose of this study was to determine the relationship of testing modifications, a type of adaptation, and the effects of demographic information on students’ standardized test scores for students in Arizona who have visual impairments including those with additional disabilities.
The sample consisted of 71 students with visual impairments in grades 2-9, including students with additional disabilities, in Arizona (U.S.). The study participants attended either a specialized school for the visually impaired or a public school with support from teachers with specialties in visually impairments.
The dependent variable in this study was participants' performance on the Stanford Achievement Test, 9th Edition (SAT-9).
Scores did not differ among individual students due to demographic factors. Limitations of the study were reported, and future research directions were suggested.
