A major argument against evaluation of teacher performance by students pertains to the instruments being used. Colleges conduct instructional evaluation using instruments they devise, borrow, adopt, or adapt from other institutions. Whether these instruments are tested for content validity is unknown. This study determined how evaluation questions were presented in a sample of 200 evaluation instruments collected from 414 schools of education. Analysis of the evaluation questions indicated that there are questions of validity in many of the evaluation instruments used by these colleges. No particular instrument is accepted by all colleges and universities, and few tests of validity have been performed for instruments in use. Flawed responses were skewed, ambiguous, or unclear, or else they did not correspond with the evaluation question. Some 58% of instruments were found to contain such flaws. Six tables and nine figures present study findings. (Contains 29 references.) (SLD)
