Your Primary Education is intended to represent the school you're currently affiliated with. You can add as many schools to your Handshake profile as needed, but can only have one school listed as your Primary Education.
If you need to update your Primary Education on your profile, you'll need to submit a ticket to Handshake's Support Team. This is because the school will need to approve your affiliation before being added.
To update the Education information on your profile, refer to How to Edit Education Information on Your Profile.
