When you try to confirm a student to take a restricted test, you will see a message with the error "Test restricted by term" under the student's name.
When opening a test session containing tests that have been restricted by term, you will see the message "These students had previously been assigned a test which is no longer available or is restricted by term or grade. If you wish to continue using this Testing Session, please click the "Ignore and Continue" button."
This message occurs when the System Administrator has restricted a test to certain testing terms. For example, end-of-course tests are often restricted to the spring term.
