Exploratory Studies CODO requirements

Current Purdue students can view the criteria to change their major to Exploratory Studies 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 criteria below to be eligible to change their 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. The major change information below is for catalog term 2020-2021; see the University Undergraduate Academic Advising Major Change (CODO) website for prior catalog term criteria and FAQs.
