This document, noting that teacher evaluation has now become a terror for teachers due to legislation such as the Stull Act, reviews the major assessment alternatives for teacher competence appraisal. The author discusses the use and merits of ratings, observations, and pupil test performance and finds them all to have fatal defects. He then describes as a final alternative the use of teacher performance tests, which he first advocated for use in the mid-sixties. The rationale behind this type of test is described as follows: since one of the major difficulties of comparing teachers for evaluation is that different teachers have different instructional emphasis, a teacher's ability to accomplish prespecified instructional objectives should be measured. The teaching performance test accomplishes this by providing an identical task for different instructors. Projects exploring this method are noted, but further experimentation is advocated. (JA)
