Reverse Transfer Efficiency Act of 2021 This bill allows the release of a transfer student's educational records from an institution of postsecondary education where a student earned credit for coursework to an institution of postsecondary education where the student was previously enrolled in order to apply the student's coursework and credits toward completion of a recognized postsecondary credential, such as an associate's degree. Specifically, the bill allows the Department of Education to provide funding to an institution of postsecondary education that releases a student's records of postsecondary coursework and credits without the consent of the student or the student's parents if the student provides written consent prior to receiving the credential.
