Description

This study investigated predictors of TOEIC Reading performance among management majors (N = 174) at a Japanese public university. Regression analyses examined the influence of initial CASEC scores, Year 1 NGSL/NAWL vocabulary levels (initial and final), and TOEIC Reading scores (Times 1–3) on Time 4 outcomes. Results showed that Year 1 final vocabulary levels strongly predicted Year 2 reading (β = 0.279), underscoring the importance of vocabulary development for TOEIC success.

Summary

Vocabulary knowledge strongly predicts reading comprehension. This study examined TOEIC Reading scores at Time 4 from management majors (N = 355) at a Japanese public university. A regression analysis assessed the predictive power of initial CASEC scores, initial and final Year 1 NGSL (and NAWL) levels, and TOEIC Reading scores (Times 1-3). Results indicated that final vocabulary levels were strong predictors of reading comprehension, emphasizing the importance of vocabulary study for TOEIC success.
