The student test authorization provides a unique identification for each test taker. Proctors print authorization letters for distribution to the students. Proctors can create, modify, or remove a test authorization. In addition, the module supports the ability to reset passwords in the event of a lockout due to excessive password guessing. The delivery system supports several types of tests, including sequential, adaptive, and random test item presentation.
Basic features prevent students from using cut and paste on items.
More advanced features provide control over the desktop to prevent access to other applications or Web surfing during the test delivery. 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.
