Accommodated students sign an agreement on file in the DRC office stating that materials are for their use only and may not be shared or sold (in a private meeting with the student you could add your emphasis to these points, if you like). Accommodations are approved by DRC when supported by documentation and a student’s particular access needs, therefore you may not deny a right to record a class. If your class format includes the sharing of sensitive information by other classmates or yourself that will not be included on a test, you may privately arrange a signal you will use to alert students to stop recording during just those portions.  If you find that a student is abusing the right to record lectures, notify the DRC, and provide your evidence.  For example, if a student uses recorded material for plagiarizing, this is a disciplinary issue.
