The functions, goals, and characteristics of test standardization are discussed, including an explanation of how score equating as an aspect of standardization is essential to the achievement of equity in testing. Psychometric specialists and testing program directors must understand score equating to ensure equitable use of tests. (Author/AL)

An important determinant of equating process efficiency is the correlation between the anchor test and components of each form. Use of some monotonic function of this correlation as a measure of equating efficiency is suggested. A model relating anchor test length and test reliability to this measure of efficiency is presented. (Author/DWH)

Equating studies using item response theory (IRT) are reviewed. The most well-known papers, as well as a sampling of lesser-known studies, are included. Accompanying tables list the papers and classify them according to the test used, models used, test length and type, sample size and type, method of assessment, equating design, and kinds of…

Improved communication and cooperation between test publishers and school systems is essential for solving major test problems. Test-curriculum matching, test equating, and inappropriate use of grade equivalent scores are major problem areas. The degree to which a standardized test yields information relevant to what the system is trying to teach…

A study involving all students taking the California Achievement Test (CAT) in the Cleveland City School District (Ohio) during the fall of 1989 was conducted to assess the effects of the use of parallel test forms. Each spring, all students in grades 4, 6, and 8 are selected to take the appropriate level of the CAT reading test, Form E. As a…

Concern was expressed for the possible effects of testing Elementary Secondary Education Act (ESEA) Title I students with norm-referenced tests that may be so difficult that many students will have scores in the chance range. The likelihood of such students obtaining equal scaled scores if they were tested with easier out-of-level tests was…

In this discussion of the use of achievement tests in evaluating Title I programs, matching content between test and curriculum is the main theme. The point is made that unless a test measures what is taught, it cannot be sensitive to whatever gains the instruction produces. Thus, if different instructional treatments have different objectives, it…
