13-37-30. Braille literary assessment and educational services for blind students. In developing an individualized written education program for each blind student the presumption shall be that proficiency in braille reading and writing is essential for the student to achieve satisfactory educational progress. The assessment required for each such student shall include a braille skills inventory, including a statement of strengths and deficits. Braille instruction and use are not required by this section if, in the course of developing the student's individualized education program, all members of the team concur that the student's visual impairment does not affect reading and writing performance commensurate with ability. Nothing in this section requires the exclusive use of braille if other special education services are appropriate to the student's educational needs. The provision of other appropriate services does not preclude braille use or instruction.
