Most often, questions arise when a student uses a tape recorder. An instructor may not forbid a student's use of an aid if that prohibition limits the student's participation in the school program. The Section 504 regulation states: A recipient may not impose upon handicapped students other rules, such as the prohibition of tape recorders in classrooms … that have the effect of limiting the participation of handicapped students in the recipient's education program or activity. In order to allow a student with a disability the use of an effective aid and, at the same time, protect the instructor, the institution may require the student to sign an agreement so as not to infringe on a potential copyright or to limit freedom of speech.
