The 206 mathematics achievement tests cited in this bibliography are used to assess students' knowledge of various mathematical skills and operations. Many of the tests described are included because one or more of their subtests measure some aspect of mathematical knowledge. Although grades 1 through 12 are represented, the tests are primarily designed for grades 7 through 12. This document is one in a series of topical bibliographies from the Test Collection (TC) at Educational Testing Service (ETS) containing descriptions of more than 18,000 tests and other measurement devices prepared by commercial publishers, teachers, educational institutions, professional associations, departments of education, counselors, etc. Each description contains the following basic information: TC Accession Number (a six-digit identification number assigned by the Test Collection); the title of the instrument; personal or institutional author; year of publication or copyright; availability source; grade level for which test is suitable; age level for which test is suitable; and abstract.
