Article is addressed to the differential susceptibility of Quantitative Comparisons, Data Sufficiency, and Regular Mathematics aptitude test items to an intensive program of short term instruction. Of secondary interest is the relative susceptibility of geometry and nongeometry items within these three formats. (Author/RK)

This paper reports the results of three sets of factor analyses. The purpose of these investigations was to determine whether, among the aptitude tests: (1) there appeared to be different aptitude patterns for Negroes and whites, (2) whether the configuration or pattern of the ratings received by Negroes and whites were related in the same way to…

Methodologies were proposed for combining background and aptitude and/or achievement information in an approach to the classification problem using the concept of under- and overachievement. The methodologies were applied to independent samples from four high school curricula. The results suggest that when past achievement and/or aptitudes were…

A differential instructional program was developed for each of three mathematics aptitude item formats to determine the relative susceptibility of each to special instruction. High school juniors were given a pretest that included items of each format and a parallel form as a posttest several weeks later. Between the pre- and posttests,…

One of the many criticisms leveled at standardized testing is that the time limits commonly used require a speed component of performance which may act to the disadvantaged of certain culturally defined groups. Recent studies by the authors examined the question of differential time limits and group performance for standardized academic aptitude…

Minority and majority groups were administered a special quantitative section of the Admission Test for Graduate Study in Business (ATGSB) under varying time conditions to determine if increasing the time allotted for the test would eliminate any bias which may exist due to an irrelevant speed factor. By a commonly employed definition the special…

A special course was designed to aid undergraduate subjects in preparing for the Graduate Record Examination--Quantitative (GRE-Q). The course included a short one-session discussion (Anxiety Reduction Session) of the GRE and its uses, and four sessions devoted to specific instruction in the basic mathematics required for the test and strategies…
