Equating the Scales of the Prueba de Aptitud Academica and the Scholastic Aptitude Test.
Angoff, William H.; Modu, Christopher C.
The purpose of this study was to establish score equivalencies between the College Board Scholastic Aptitude Test (SAT) and its Spanish-language equivalent, the College Board Prueba de Aptitud Academica (PAA). The method of the study involved two phases: the selection of test items equally appropriate for Spanish- and English-speaking students for use in equating the two tests; and the equating analysis itself. The method of the first phase was to choose two sets of items, one originally appearing in Spanish, the other originally appearing in English; to translate each set into the other language; and to administer both sets in the appropriate language mode for pretest purposes to both types of students. These administrations were conducted in the Fall of 1970 with samples of condidates taking the PAA or the SAT at regularly scheduled administrations. They provided data regarding the difficulty and discrimination power of each item for each of the two groups, and an index of appropriateness of each item for both groups. On the basis of the analyses of these data, two sets of items, one verbal and the other mathematical, were chosen and assembled as "common items" to be used for equating. In the second phase of the study, these "common items," appearing in Spanish and in English, were administered in the appropriate language along with the operational form of the PAA in November 1971 and with the operational form of the SAT in January 1972. The data resulting from the administrations of these "common items" were used to calibrate for differences in the abilities of the two groups and permitted both linear and equipercentile equating of the two tests. Conversion tables are provided. (Author/DB)
