Changing Your Major
A Change of Curricula (CODO) occurs when a Purdue West Lafayette student requests to transfer to a program in another college or school in the University. To prepare for a successful CODO, students should review and meet all of the requirements which have been set forth by the College of Science for their program of interest. CODO requirements vary within the College and will not be waived. The College of Science recommends the following process to ensure a successful CODO process.
- Talk to your current advisor
Work closely with your current advisor to understand and complete the CODO requirements of the College of Science program you would like to pursue.
- Talk with an advisor in your program of interest (optional)
Connect with the College of Science during non-major drop-in times to discuss your CODO plan.
- Start the CODO process with your current advisor
The College of Science will receive your request electronically.
