This fact sheet provides guidelines on adapting testing situations for disabled postsecondary students. Discussed in the first section are considerations in determining when testing adaptations are needed including disability verification procedures, policy consistency, and maintenance of academic and technical standards. Facts about disabilities are then presented regarding functional limitations, hidden disabilities, disabilities that fluctuate over time, unpredictable disabilities, and the different needs of recently disabled students and students who have been disabled since birth. Specific testing adaptations are offered for students with hearing, vision, mobility, speech, and emotional impairments as well as general guidelines on the test environment, use of proctors and assistants, extended time limits, and measurement of laboratory performance and vocational-technical mastery. The final section recommends having an office which coordinates disabled student services and describes two organizations which provide resources on assisting disabled postsecondary students.
