Non-Krannert Student Prerequisite Override

Do you want to take a Krannert course but may not have the necessary prerequisite? Or do you believe the prerequisite is similar to another course you took? Follow the steps below. Any questions, please e-mail us at

  1. Contact the instructor for the course you want to take and request a prerequisite override. Please note, permissions are up to each instructor. If the instructor denies your request, you will not be able to take the course.
