Criticism of vocabulary assessment “…vocabulary assessment is grossly undernourished, both in its theoretical and practical aspects – it has been driven by tradition, convenience, psychometric standards, and a quest for economy of effort rather than a clear conceptualisation of its nature in relation to other aspects of reading expertise.” Pearson, Hiebert & Kamil (2007)
