This report discusses the attitudes of Wyoming teachers toward tests and their use. The teachers' educational background in tests and measurement; the use of tests by teachers; and the classroom testing practices of teachers were evaluated. A questionnaire was developed and administered. The results indicated that Wyoming teachers' testing practices are consistent with results in other states. On the average, Wyoming teachers spend six hours a week constructing and giving classroom tests. They use tests to measure student achievement, evaluate their own teaching. determine grades, identify weaknesses, review material, and for ongoing assessment. Over 90 percent of Wyoming teachers believe that standardized tests are not the best way to evaluate a teacher's effectiveness. Almost 60 percent believe that teachers understand standardized test results. Over 60 percent believe that a competency test requirement for students would raise educational standards. Attitudes toward classroom tests were, on the average, slightly favorable, while attitudes toward standardized tests tended to be unfavorable. The survey instrument is appended. (DWH)
