Oregon Revised Statutes Education and Culture § 343.575

(1) In developing the individualized education program for each student who is blind, the presumption shall be that proficiency in reading and writing is essential for the student to achieve satisfactory educational progress. Each student who is blind shall be assessed to determine the most appropriate learning media, including but not limited to Braille. The individualized education program team shall determine the optimum learning media.

(2) 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.

(3) Nothing in this section requires the exclusive use of Braille if other special education services are appropriate to meet the student's educational needs. The provision of other appropriate services does not preclude Braille use or instruction.
