Two Versions of TOEIC？？ as a Placement Test: A Comparative Study Based on the Classical Test Theory and Rasch Model

This is the fifth report on the research project which compared the older version of the TOEIC？？ test with the new one. Through an examination of the ability measures based on the Rasch analysis, it is confirmed that there is a relatively high degree of parallelism between the two versions of the TOEIC？？ in terms of examinees’ placement. A close examination of the exceptional measures revealed that 6.6% of the total 136 test takersmight have been misplaced due to personal factors such as lack of test time and lack of interest in answering questions. However, it is still too early to conclude that the observed differences are due to either test format or personal factors, or both.
