The purpose of the study described in this report was to explore the relationships between College Board Achievement Test scores and potential scaling covariates for various subgroups of the test taking population. Periodic scalings of the ATP Achievement Tests have not been carried out since 1980. The goal of the study was to provide several alternatives to the scaling procedures traditionally used for the Achievement Tests. The alternatives will, by their nature, vary components such as scaling covariates, scaling samples, and characteristics of the hypothetical reference group. First, the results of an investigation of the characteristics of the scaling sample are discussed. Second, the choice of additional scaling covariates and their relationship to clusters of tests are summarized. Third, the results of the examination of the characteristics of the hypothetical reference group are discussed. (190pp.)
