Non-commercial investigator-developed tests and other instruments to assess mathematical instruction, reported in journals, dissertations, and ERIC documents from 1974 through mid-1981, are listed. For approximately 90 instruments, information on content, format, sample, reliability, correlations, and validity is included, as well as references. Other instruments for which only partial information was available are also cited on a supplementary list, followed by a list of references for this supplement. An index lists instruments by cognitive topic or as affective assessment or teaching analysis tools. An index of authors and educational levels concludes the document. (No instruments included.) (MP)
