Many disabilities are not readily apparent. More prevalent nonvisual disabilities include seizure disorders, diabetes, HIV, cardiac conditions, allergies, carpal tunnel syndrome and chronic back or shoulder pain. Most of these disabilities are referred to as "hidden" because one can not identify them just by looking at the person.

The types of problems that these students may face in higher education involve chronic health problems and physical limitations. Students who have chronic or acute health problems may exhibit a low tolerance for prolonged physical activity, they may move at a slower pace, or they may appear lethargic or hyperactive due to medication(s) that they are taking. In case of students with severe allergies or asthma, environmental aggravations such as dust, pollen, chemicals and fumes can exacerbate their condition.

Instructional strategies and potential accommodations

• Absences may need to be accommodated for students who miss class to receive medical treatment.
• Course requirements such as physical education may need to be modified.
• Extended time for completion of course work may be necessary.
• Classrooms may need to be a controlled environment.

Test adaptation and administration alternatives

Rescheduling of exams may be necessary if the student is physically unable to take it at the scheduled time/date.

Extended time may be needed to complete exams.

The testing area may need to be not only a controlled environment, but also distraction free.
