In addition, all items are loaded into client memory so that they are not cached to the hard drive on the client PC by the browsers. In this situation, the student's user ID and password alone are not sufficient to access the test. The test proctor must 'claim' students for a particular test session and release and terminate the student authorizations at the beginning and end of the test session. This is the first part of a double authentication system. The Proctor must enter a user ID and password before the system can be accessed.
Students have a user ID and password.
This is the second part of the double-authentication system. Students can view only their own examinations. The test delivery display hides the standard toolbars, so that print and save functions, as well as spell check and the thesaurus, are not accessible. Therefore, test items and the tests can not be kept in the classroom or school once the administration is complete. If a pattern of response changes is detected within a group of students, further investigation can be undertaken to determine if there is a reason for the pattern.
