CODO (Major Change) Requirements

Are you thinking of changing your major? At Purdue that’s called a CODO (Change of Degree Objective), and you start the process by reaching out to your current academic advisor for guidance.

Current Purdue students wishing to change their major (CODO) to a new major can view the criteria to change their major here through the links below. Purdue students interested in changing their major should meet with their current academic advisor to discuss their options and begin the online process. Once the student’s Major Change (CODO) has been processed, students will receive an email with instructions to authorize the change.

Students will need to meet the major change criteria to be eligible to change to a new major. A student’s catalog term, typically the semester you started at Purdue, will be used to determine the Major Change criteria that applies to you. Students can find their catalog term at the top of their MyPurduePlan below the degree progress bar.
