The General Assembly finds that proficiency in braille reading and writing is essential for the satisfactory educational progress of visually impaired students and that braille instruction must be used in combination with other special education services that are appropriate to the educational needs of visually impaired students; therefore, it is hereby declared to be the policy of this state to provide, and to require school districts to provide, all visually impaired students who are enrolled in Arkansas public schools and whose education is adversely affected by their visual disability with an equal opportunity for appropriate instruction. Appropriate instruction shall be designed to enable each visually impaired student to communicate with the same level of proficiency as other students of comparable ability at the same grade level.
