In order for any supervisor that you had as a student employee at the College to release information on you regarding your employment you will need to Complete the Information Release and Waiver Agreement.

Once complete submit to the Student Employment Office where they will keep it on file. It's also recommended that your supervisor retain a copy. Without completion of this form no one from the College will be able to release any information on your work except the title you held and your dates of employment.
