The UNC-Chapel Hill chapter of the AAUP condemns the secret recording of any instructors for any purpose. This practice violates ethical standards and the law. The “prevailing academic practice,” according to the national AAUP’s surveying of colleges and Universities across the United States, deems faculty as the copyright owners of their teaching content. As such, recording the teaching of any content by any instructors for any purpose without their consent violates that principle and copyright law. Furthermore, UNC’s own policy states: “A classroom recording should not be used for any purpose except to meet the educational objectives of that particular class.” (See also UNC's policy on “Recording Classes Best Practices.”)
