For example, since the student and the instructor are not in the same place when an examination is given, how does the program ensure that the right person takes the test? Some accredited institutions require fish-eye cameras, which are now quite inexpensive, to be attached to computers in order to photograph the person using the computer. Others conduct biometric procedures, such as retina scans or thumbprints, to make sure that the person taking the test is indeed the person who signed up for the course. Finally, you should be aware that many programs require examinations to be proctored by a consular official, member of the clergy, officer in the U.S. armed services, or faculty member of a U.S.-accredited institution.
