This document outlines the structure and procedures of the Vocabulary and Expression Usage Test (VEUT) used to assess English language proficiency. The VEUT involves role-playing conversations between a tester and test-taker using targeted vocabulary words. The tester guides the conversation and records the test-taker's responses, evaluating their comprehension and use of the words. Results are analyzed to interpret progress over multiple tests. Role-plays are concluded to effectively assess vocabulary usage in context through interactive practice that promotes language development.
