Economics (BA) Major Change (CODO) Requirements


Major Change (CODO) Requirements


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 for this 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.

This major change information below is for the catalog term you are currently viewing; see the University Undergraduate Academic Advising Major Change (CODO) website for prior catalog term criteria, more about the major change process and FAQs.

Students changing their major to a space restricted program, as designated by SPACE AVAILABLE BASIS ONLY, need to have their Curricular Change Request (CCR) submitted by their home college/school by 5pm the Thursday of Finals week for requests effective the following term to be considered.
