This study provided a quantitative analysis of a random sample of 167 National Disability Law Reporter-published letters of findings by the U.S. Department of Education's Office for Civil Rights in response to higher education student complaints under Section 504 and the Americans with Disabilities Act. Inasmuch as each letter of findings contained, on average, two issues, a total of 346 issue rulings were the basis of the analysis. The number of these rulings per year was lower during the last five years of the 1990-98 period of the study. The outcome of the rulings favored the institutions of higher education, over the student complainants by a 2:1 ratio; however, the ratio in favor of institutions was lower for letters of findings as a whole because each letter covered approximately two issues. Type of the disability and type of the issue were significant outcome-related factors. More specifically, the success rate was significantly higher for students with mobility or hearing impairments and for complaints regarding general institutional requirements and facilities accessibility than for students with other disability or issue categories.
