Braille print, designated commonly as revised Braille Grade Two, shall be taught in the School for the Blind. The use of this print shall be included in the high school literary courses of students in such school. Every teacher or instructor in the School for the Deaf, whose duties include oral instruction of pupils, shall become acquainted with the most efficient and advanced methods of lipreading, but every teacher shall also master the manual alphabet in order to be able to communicate with pupils who cannot read lips and in order to aid and participate in student activities outside the classrooms. Every pupil entering the school shall be given oral instruction until it is clearly determined whether he can master lipreading to an extent enabling him to progress satisfactorily in his studies, but manual instruction shall be provided in all subjects for all pupils unable to progress satisfactorily under oral instruction alone. The State Board of Education may set and determine the additional requirements necessary for each teacher or instructor. All teachers and instructors must enter into written contracts of employment to indicate and cover the period for which they are respectively employed. Complete courses in shorthand and typewriting are to be offered at the School for the Deaf.
