Do you need a Verification of Enrollment (VOE) Form for your driver's permit?

VOE is a form that you submit to the DPS when you are applying for a learner's permit or license. It is signed by your school administrator to verify that you are enrolled in school, attending 90% of classes in the semester prior to your application, and that you have been awarded credit for each class you took in the semester prior to applying for your license. If you need to obtain this form, please download and complete the following form and drop it off at CAST STEM. Please be sure to drop it off 24 hours in advance of when you need it. Mrs. Shaeffer will verify your attendance and credits before signing the VOE.
