Six editions of Scholastic Aptitude Test-Mathematical (SAT-M) were factor analyzed using confirmatory and exploratory methods. Confirmatory factor analyses (using the LISREL VI program) were conducted on correlation matrices among item parcels--sums of scores on a small subset of items. Item parcels were constructed to yield correlation matrices…

To identify broad classes of items on the Scholastic Aptitude Test that behave differentally for handicapped examinees taking special, extended time administrations, the performance of nine handicapped groups and one nonhandicapped group on each of two forms of the SAT was investigated through a two-stage procedure.

This study developed, applied, and evaluated a theory-based method of detecting the underlying causes of differential difficulty. The method was applied to two subgroups taking the Scholastic Aptitude Test-Mathematics (SAT-M), 261 visually impaired students taking Braille forms of the test and 1,985 black students at 3 test administrations. It…

This study investigated whether or not the validity of the Scholastic Aptitude Test (SAT) is both higher and less variable across colleges than it appears to be. Data from 99 validity studies conducted by the Validity Study Service of the College Board were used. In addition to test validities based on first-year college averages, which were…

A previous study of pre-equating the Scholastic Aptitude Test (SAT) using item response theory provided unacceptable equating results for SAT-mathematical data. The purpose of this study was to investigate two possible explanations for these unacceptable pre-equating results. Specifically, the calibration process, which made use of the…

A review of the literature concerned with validity data and policies for various methods of treating multiple scores is reported, as are analyses of data from the College Board Validity Study Service. The analyses evaluated the use of Scholastic Aptitude Test--Verbal alone, Scholastic Aptitude Test--Mathematical alone, and the use of both in…

Score linkages between the Verbal and Math sections of the SAT® I: Reasoning Test and the corresponding sections of the new version of a Spanish-language admissions test, the Prueba de Aptitud Academica® (PAA™) were investigated. A bilingual group design was employed. A language proficiency measure (ESLAT) was used to define the bilingual group…
