You can delete a student record if:

A student moves to a new school/district/state outside of his/her enrolled organization.
The student has not signed in to start testing.

If a student is testing, you cannot delete the student record.

When you delete a student record, the system deletes the test and group assignment, and test administration registration.

Prerequisites
