Equating the Scores of the "Prueba de Aptitud Academica" and the "Scholastic Aptitude Test." College Board Report No. 88-2.
Angoff, William H.; Cook, Linda L.
With some procedural differences, this study replicated an early study designed to develop algorithms for converting scores on the Scholastic Aptitude Test (SAT) with those on the Prueba de Aptitud Academica (PAA) scale and vice versa. The study involved selection of test items equally appropriate and useful for English- and Spanish-speaking students for use as an anchor test and the equating analysis itself. Once the items were selected, they were administered as pretests, one for each language, to determine whether the two response functions for each item were sufficiently similar for the items to be considered equivalent. On the basis of these analyses, 39 verbal and 25 mathematical items were selected for use as anchor items for equating. The anchor tests were administered at regularly scheduled administrations of the SAT and PAA. An item response theory model was used to equate the two tests. The equating itself showed curvilinear relations in both verbal and mathematical tests, indicating that, in this instance, both sections of the PAA are easier than the corresponding SAT sections. Differences between these findings and those of the previous study by W. H. Angoff and C. C. Modu (1973) are assessed. Six graphs and six data tables are provided. (TJH)
