According to UC policy and disability law, students with disabilities must be permitted to audio-record when doing so is approved as a disability accommodation.
UC Policy PACAOS 140, "Guidelines Applying to Nondiscrimination on the Basis of Disability" page 8 specifically states:
Any prohibition against the use of tape recorders or braillers in classrooms, or dog guides and service dogs in campus buildings, or other rules that have the effect of limiting the participation of qualified students with disabilities in educational programs, services, or activities, may not be adopted. Students or participants with disabilities in University programs, services, or activities may be required to sign an agreement that they will not release tape recordings or transcriptions of lectures, or otherwise hinder the ability of a professor to obtain a copyright.
Each student who has the DSP-approved accommodation of audio recording in your class has signed an audio recording agreement, verifying that they will use the recording for their own personal study and that they will not share or distribute the recording. DSP can provide you a copy of any student's agreement for your records at your request. If you would prefer, DSP can also ask that students delete the recording once they have received their final grade for the course.
Students with audio recording accommodations in your class should be permitted to record your course meetings from the issuance of their accommodation letters forward. If you would like to discuss additional questions or concerns about this accommodation, please contact the student's assigned Disability Specialist directly.
