Because the College Scholastic Ability Test (CSAT) is such a high-stakes national examination, it influences not only high school students, parents, and educators, but also English teaching and learning in Korean EFL classrooms in high schools. Many studies analyzed the English-language section of the CSAT. In the same vein, regularly conducted mock CSATs are also valuable data points for test-takers and test-developers. However, little research examined whether Mock CSATs measure what they are supposed to measure. This study aims to report the item analysis results for the English section of the Mock CSAT administered by the Seoul Metropolitan Office of Education in March 2018. It consists of listening and reading sections with five option multiple-choice items. Two hundred forty-nine Korean first grade high school students participated in this study. Their responses to each test item were reported as the result of item analysis with respect to three indices: item facility, item discrimination and distractor analysis. The results identified that the average of item facility was 64.8%, which means that the difficulty level was suitable for the test-takers. Item discrimination was 0.42, which indicates the test had a high discrimination power. Therefore, this study suggests that providing more plausible distractors enhance the overall test validity and reliability for future CSAT administrations.
