Test takers' preferences for group versus individual administration of the Micro-TOWER System of Vocational Evaluation are reported. The system was administered to 211 clients at a vocational rehabilitation center, and consisted of work samples measuring the following job skills: record checking, filing, lamp assembly, message-taking, zip coding, making change, want ads comprehension, and payroll computation. Because the Micro-TOWER is administered to groups of two to ten people, the test developers were interested in whether or not this method of testing generated negative reactions that might interfere with test performance. It was found that the clients taking this test preferred group to individual testing at the rate of approximately two to one. This ratio was consistent and independent of the individual evaluator administering the test, the nature of the work sample, and the group size. There was, however, a slight tendency for increasing preference for group testing as the size of the group increased. The authors suggest that group testing provides these advantages: the clients encounter a supportive atmosphere; the evaluator has more opportunities to help the test takers who need assistance; and this means of testing is more appropriate for current employment situations in which a large number of people must be served.
