The goal of this project was to develop and field test training materials for students and teachers which would increase the probability of obtaining valid test results from the administration of standardized group achievement tests. The specific objectives were: (1) to produce a self-instructing videotape illustrating correct and incorrect test administration practices; and (2) to train teachers to implement appropriate test administration procedures during group achievement testing. The videotape developed was shown to elementary teachers prior to testing. The tape contains scenarios that model procedures for training students in test taking skills and that demonstrate examples and nonexamples of standardized test administration techniques. After this training, a field test was administered to evaluate its success in the improvement of the quality of test administration. Results of the data collected, indicate that teachers trained with the videotape were significantly more on-task than a control group; and students in the trained teachers group received significantly higher test scores than students in the untrained group. The implications of having trained teachers administer group tests is that a more accurate measure of achievement is obtained. (Author/AEF)
