umber of specifically selected tests are employed together to predict a single criterion. In order to have a practical criterion, several tests might be administered. Most of the time, to establish these criteria the test administrator depends on a number of diverse traits. If a single test where to be administered, such test would have been heterogeneous.When it comes to analyzing such battery of tests, the problem arises when the diverse scores have to be combined in order to arrive at a decision that concerns each individual.There are two major procedures to follow when administering the test battery; these are the Multiple Regression Equation and the Profile Analysis. The Multiple Regression Equation provides the tester a predicted criterion score for each individual on the basis of his/her score on all tests in the battery.The Profile Analysis and Cutoff Scores are the procedure that involves the establishment of a minimum cutoff score on each test. When this method is used at the evaluation, anyone who falls below the minimum score, “an anyone of the appropriate test” is rejected.There are several well known Test Batteries. These are the Thematic Apperception Test, the House Tree Person, and the Bender Gestalt, also the IWA is another one of them.TATThe TAT, or the Thematic Apperception Test represents a most highly structured stimuli and requires a more complex and meaningful organized verbal responses. The interpretation of such test is based on content analysis, and not a qualitative nature.This test consists of 19 cards containing pictures in black and white and one card blank. The person being tested is instructed to make-up a story to fit each picture describing what is happening and what led up to the events in it. He/she has to talk about feelings, what the character might be thinking and then instructed to imagine what is happening in the blank card.HTP (House Tree Person)This is one of the most used pr...
