| Summary: | The possibility of administering tests by projected methods was explored, focusing on the assignment of values to specific test variables in order to make the results of projected tests comparable to those of a normal (classroom teacher administered) test environment. The variables of (1) intra-item exposure interval, (2) inter-item exposure interval, (3) items per exposure, (4) audiovisual and visual item presentation, and (5) item-difficulty arrangement were incorporated in the project. Contents of intelligence, achievement, vocational interest, and adjustment tests were subjected to study. Still slides were chosen for projecting the test data. These slides were easily and inexpensively produced and were adaptable to varied administrative conditions for testing. During testing, some of the test items were read from tape as they appeared on a screen. Subjects ranged from elementary to graduate college students, depending on the level of difficulty of a particular test administered. Results demonstrated some amount of equivalence between the projected test mode and normal testing conditions, although pairs of means and variances were at times significantly different. One method would be regarded as interchangeable with the other when the correlation between the sets of scores obtained under the two administrative conditions was high (approaching or equal to the reliability of the test when determined on a test-retest basis under normal conditions).
