In developing the individualized educational program for those students who demonstrate loss of functional vision that renders the reading of print inefficient, the presumption shall be that proficiency in Braille reading and writing is essential for the student to achieve satisfactory educational progress. The assessment performed for each visually impaired student shall include a Braille skills inventory, including a statement of strengths and deficits. Braille instruction and use shall not be required if, in the course of developing the student’s individualized education program, all members of the planning and placement team concur that the student’s visual impairment does not affect reading and writing performance commensurate with his or her ability. The provision of other appropriate services shall not be precluded by the use of Braille. Nothing in this section shall be construed to require the exclusive use of Braille if other special education services are appropriate to the student’s educational needs.
