Analalysis of the construct validity of the TOEIC test when used as an English proficiency evaluation tool

This study sought to verify the usefulness of the TOEIC English proficiency test. TOEIC is recognized as an official English proficiency test, but more empirical evidence is needed to verify the test’s usefulness. To evaluate TOEIC test usefulness, the study assessed the construct validity of the test by conducting a correlation and causal relationship analysis of the connection between class scores given by native English-speaking teachers (NESTs) and TOEIC test scores. The results showed a significant correlation and causal relationship between TOEIC scores and NEST’s scores. However, there was only a weak correlation and causal relationship between TOEIC scores for classes taught by NESTs. TOEIC listening scores showed only a weak causal relationship with scores from NEST speaking classes. This suggests that the construct validity of the listening part of the test was not as strong as for TOEIC reading. Consequently, TOEIC scores do not correlate well with the NEST’s class scores, which have a high construct validity. Therefore, it can be seen that the TOEIC test has poor validity when measuring communication skills. In conclusion, in the future, there is a need to improve the construct validity of the TOEIC test, which is an officially recognized test.
