Academic word coverage and language difficulty of reading passages in College English Test and Test of English for Academic Purposes in China

Abstract

The field of English for Specific Purposes (ESP) has gained considerable attention, mainly due to the growing importance of English teaching and the need for preparing international professionals. The primary academic emphasis of this field is largely centered on the study of English for Academic Purposes (EAP). It has become increasingly important for China to provide EAP education to its vast population of college students, who represent a significant proportion of global tertiary-level English learners. By doing so, they can improve their academic literacy and participate more effectively in international academic communication. In 2016, China’s College English Test Examination Board issued the National College English Test Syllabus which emphasized the importance of academic English literacy in the test design. This syllabus was released during a contentious debate among Chinese academics about the role of EAP in college English teaching and testing. Despite this heated discussion, there are currently few studies that have analyzed the linguistic nature of academic English tests in a quantitative manner. This paper calculates the academic word coverage of the reading passages in two crucial English proficiency tests designed for college students in China, the College English Test (CET) and the Test of English for Academic Purposes (TEAP). It is found that the academic word coverage of CET is increasing from the year 2013 to 2021 and that the academic word coverage of TEAP is slightly higher than that of CET. In this sense, these English tests can meet the requirements for measuring Chinese college students’ academic literacy. It is also found that there is a positive correlation between academic word coverage and language difficulty as is indicated by Flesch–Kincaid Grade Level. These findings provide an empirical reference for the study of academic English tests in China, and other parts of the world, and contribute to EAP teaching and testing reform for the development of students’ academic literacy.
