Abstract: A method of proctoring an examination taken by a student at a remote site uses a student's computer connected over a network to a test administration server. Before a student takes a first examination, a pre-examination sample of the student's voice is recorded. At a designated examination time, a network connection is made between the student's computer and the server computer. The student logs-in and is prompted to make a telephone call, to enter a code on the telephone keypad, and to provide a start-of-examination voice sample. After the student answers at least one exam question, and the answer is uploaded and removed, the student is prompted to make another telephone call, to enter a code, and to orally summarize or explain the prior answer. An instructor may letter retrieve and compare such voice samples to detect cheating.
