Visual impairment is a low prevalence disability.
It is commonplace for a district to serve only one student or perhaps one to three students with a visual impairment. These students will represent varying levels of ability. They may be deafblind or have additional disabilities in combination with blindness or a visual impairment. And every different combination of disabilities requires specific adaptations and instructional strategies in order to maximize the student's learning potential. It provides parents and professionals with a wealth of information on topics related to the education of students who are blind, visually impaired, and deafblind.
