Sec. 5. (a) In developing the individualized education program for a blind student, the presumption is that, with some exceptions, proficiency in braille reading and writing is essential for blind students to achieve satisfactory educational progress.
(b) This chapter does not require braille use or instruction if, in the course of developing a blind student's individualized education program, the student's case conference committee determines that another medium:
(1) is more appropriate and efficient in meeting the student's reading and writing needs; and
(2) allows the student to achieve in instructional activities commensurate with the student's potential.
(c) This chapter does not require the exclusive use of braille and the availability of other media may not preclude braille instruction if, in the determination of a blind student's case conference committee, braille is necessary for the student to achieve to the student's potential.
