摘要：
Administered annually in January by the College Entrance Examination Center (CEEC) in Taiwan, the General Scholastic Ability Test (GSAT) is a high-stakes college entrance testfor high school seniors. Thisstudy aimed at validating the multiple-choice (MC) items of its English subtest (GSAT-ES)usingconfirmatory factor analysis (CFA). The GSAT-ES contains a total of 56 MC items groupedinto three sections: vocabulary (15 items), cloze items (25 items)and reading comprehension items (16 items). In thisstudy, two datasets (one for 2015 and one for 2016) were provided by CEEC, with eachset containing 5,500 randomly-selected test-takers' responses to the 56 MC items. Performed by a panel of five raters, the vocabulary and cloze items were classified into four language components developed byPurpura(2004), andthe reading comprehension itemswere classified into two reading sub-skills developed byPurpura(1999). Then CFAs were applied to the two sets of data. For both years, theCFA results showed that the raters' item classifications failed to fit the test-takers' responses. Instead, based on three common measures, the single-factormodel best captured the characteristics of the data, suggesting that the threeMCsections together appeared to tap into the general English reading ability rather than a numberof divisible reading sub-traits. Finally, based on the results of the study,some pedagogical and practical implicationscan be drawnfor English teachers and test constructors.
