<P> There are many advantages to group tests over individual tests . Group tests are much more time - efficient in many aspects . For example, group tests are administered to many people at once; to test each person individual is unrealistic . Group tests also are much easier to score because they are dominantly multiple choice . More time is taken to score short answer or essay - based questions, but these are still much quicker than scoring each person's individual answers . Scoring is also more objective and more reliable since subjectivity of the grader is not as prevalent . These tests are also more cost - efficient since they don't require expensive materials or extensive training of administrators . </P> <P> With the many benefits that are associated with groups tests, it is important to consider some of the downfalls also associated with group tests . First, while these test scores can give some predictive aspects to secondary school achievement, college success, or graduate school success, these scores need to be considered with other factors in mind . Kaplan and Saccuzzo suggested to "be especially careful in using these tests for prediction, except for predicting relatively limited factors over a brief time" (p. 308). Particularly when being consider for undergraduate or graduate school admissions, multiple aspects needs to be considered for a complete evaluation . </P> <P> Another caution to consider with group tests is the aspect that the administrator can play a large influence when problems occur during individual tests . For example, when a problem arises, the administrator can address the problem in order to allow maximum performance for the respondent . Also, a lot of information can be learned about the subject beyond the score itself with individual tests . The administrator is able to work with the respondent in a standardized format while still helping when help is needed . </P>
