The purpose of this study was to evaluate the validity of the rational consideration of reasonable accommodations to be made for students with disabilities and to draft an appropriate standard. Seven health management or student support professionals involved in this study. Five fictional cases of disabilities (auditory impairment, physical disability, developmental disorder (2 cases), internal disability) and 80 examples of reasonable accommodations were prepared. The participants evaluated the validity of each example on a scale of 1 to 9. The results were revised and aggregated in accordance with the Delphi method. Examples of reasonable accommodations commonly evaluated as “moderately or highly valid” among the participants were as follows. “Providing lecture materials in absence due to hospital visit”, “Extending the deadline for submission of papers”, “Notification of schedule changes online or by sending notes”, “Prior notification in writing of processes, time limits, and precautions”, “Giving necessary advice on filling out application and other forms”, “Providing transition support for employment”, and “Holding workshops on disability support for faculty, staff, and students”. Constructive dialogue with students with disabilities is important to determine the most effective support methods. Moreover, it is also useful to know which reasonable accommodations are considered highly “valid” or “reasonable” based on quantitative evaluations.
