From Reports → Service Sites, you'll see every organization your students have logged hours with — both partner orgs on Yura and outside organizations entered through the external verifier flow.
External organizations (those not on Yura) are flagged with a distinct icon so you can see at a glance which hours were verified by an outside supervisor vs. an in-platform org admin.
If you see many students logging hours at the same external org, reach out and invite them to join Yura. In-platform verification is faster and more reliable than email-based external verification.
