The Elicited Imitation Test (EIT) is widely recognized for its reliability in research settings as a proficiency assessment tool. However, there exists a need to examine its predictive validity in English as a Foreign Language (EFL) classrooms. This study investigates the extent to which the EIT, alongside the Oxford Placement Test (OPT), can predict students' academic achievements in an English for Academic Purposes course, including overall grade point average and scores in listening, speaking, grammar, and vocabulary. The study also examines the relationship between students' perceptions of their listening and speaking skills and their EIT performance. The study involves 41 participants, with data analysis conducted using both regression and correlation methods. Results show that the EIT significantly predicts students' grade point average and language skills. Students' self-perceived speaking and listening abilities reasonably align with their actual performance on the EIT, and it seems that factors related to comprehension weigh heavily in their considerations. These findings have significant implications for EFL research and pedagogy.
