Procedures used to compare the results from item response theory as well as more traditional equating methods were described and critically analyzed. The implications of the comparison of equipercentile, linear, one-parameter (Rasch), and three-parameter methods for equating twelve forms of each of the five tests of General Educational Development…

The American Council on Education (ACE) Commission on Educational Credit and Credentials adopted a plan for a 5-year review of the General Educational Development (GED) program. This review process was intended to ensure that the GED program, which operates in Canada and other countries, as well as in the United States, will address and measure…

This paper summarizes much of the available information concerning the reliability and validity of the Tests of General Educational Development (GED Tests). The data suggest that the results are sufficiently reliable for continued use and that the validity evidence generally supports the intended uses of the tests. (Author/LMO)

Argues that the results of College Level Examination Program (CLEP) tests, nationally recognized, high-quality examinations conventionally used to award college credits, should be included in students' grade point averages. This would provide important information to graduate schools. Regents College (New York) has adopted a procedure for…

The adequacy of equipercentile, linear, one-parameter (Rasch), and three-parameter logistic item-response theory procedures for equating 12 forms of five tests of general educational development were compared. Results indicated the equating method adequacy depends on a variety of factors such as test characteristics, equating design, and sample…

Procedures and related issues involved in the application of trait-treatment interaction (TTI) to institutional research, in general, and to placement and proficiency testing, in particular, are discussed and illustrated. Traditional methods for choosing cut-off scores are compared and proposals for evaluating the results in the TTI framework are…

In response to informal reports that the time limitations on the new 1978 test forms of the General Educational Development (GED) Tests resulted in some examinees having to work substantially faster than at a comfortable rate, this study was designed (1) to estimate the time required for examinees to complete the tests at their preferred rate; (2)…

Since 1971, nearly four million adults have qualified for a high school equivalency credential based on General Educational Development (GED) test results. During Spring 1980 two major studies were undertaken by the GED Testing Service: (1) the U.S. High School Norming Study involving the administration of the GED Tests to a representative sample…
