The Vocabulary Levels Test has been widely used in language assessment and vocabulary research despite never having been properly validated. This article reports on a study which uses a range of analysis techniques to present validity evidence, and to explore the equivalence of two revised and expanded versions of the Vocabulary Levels Test.
