Validation of C-Test among Iraqi EFL University Students

This study aims to assess the performance of university students through the C-Test and to analyze the extent to which this test is valid in measuring language ability. A standardized C-Test has been created with four brief passages, each containing ۲۰ gaps. The length of each passage varied from ۹۵ to ۱۰۹ words. Throughout each passage, only the first and last sentences were not changed. The test was taken by ۱۰۰ students; ۳۹ were male and ۶۱ were female at Al-Nisour University/Department of English in Baghdad, Iraq. The sample consists of two groups. Both groups come from the same school and would receive similar educational input in both cases based on their grade level. The validity and reliability of the C-Test were investigated using various techniques. The study analyzed the performance of Stage ۴ and Stage ۳ students on the Common Language Proficiency Test in Iraq. The results showed that the test discriminates well between high-ability and low-ability examinees, with no significant difference between the two groups. The Rasch model separation reliability was relatively high, and the data were one-dimensional. The students faced difficulties in guessing the most appropriate words due to their limited English proficiency. The results suggest that developing and implementing this test could significantly improve students' academic achievements in basic foreign language classes in Iraq.
