Stanford Achievement Test—8th Edition: Reading Comprehension Subgroup Results

The following pages contain a set of five graphs depicting the median scaled scores and corresponding grade equivalents (GEs) on the 8th Edition Stanford Achievement Test (SAT-8) Reading Comprehension subtest for various groups of deaf and hard of hearing students. The median scores used in these graphs were extracted from a series of special decile norms computed for the population of deaf and hard of hearing students in the United States during a special achievement test project conducted by the Center for Assessment and Demographic Studies (CADS). Since this population is heterogeneous with respect to various demographic, audiological, and educational characteristics, misconceptions could occur when interpreting the scores of individual students. For example, if a particular student has handicaps in addition to hearing impairment, it may not be useful to compare that student to the entire population of deaf and hard of hearing students. An individual student may also belong to more than one relevant group. Thus, it is appropriate at times to use more than one set of group norms when interpreting a score (e.g., handicap status norms, ethnic group norms, and program type norms). A complete listing of the special group norms is available in:
