The academic section of the Vocabulary Levels Test (VLT-Ac) and the Academic Vocabulary Test (AVT) both assess meaning-recognition knowledge of written receptive academic vocabulary, deemed central for engagement in academic activities. Depending on the purpose and context of the testing, either of the tests can be appropriate, but for research…

The Peabody Picture Vocabulary Test (PPVT) is a widely used test of receptive vocabulary, but no researchers to date have examined the performance of low-educated, low-literate L2 adults, or compared these individuals' performances to their more highly educated peers. In this study, we used many-facet Rasch analysis and mixed-effects linear…

Vocabulary's relationship to reading proficiency is frequently cited as a justification for the assessment of L2 written receptive vocabulary knowledge. However, to date, there has been relatively little research regarding which modalities of vocabulary knowledge have the strongest correlations to reading proficiency, and observed differences have…

Placement and screening tests serve important functions, not only with regard to placing learners at appropriate levels of language courses but also with a view to maximizing the effectiveness of administering test batteries. We examined two widely reported formats suitable for these purposes, the discrete decontextualized Yes/No vocabulary test…

This study examines the development and evaluation of a bilingual Vocabulary Size Test (VST, Nation, 2006). A bilingual (English-Russian) test was developed and administered to 121 intermediate proficiency EFL learners (native speakers of Russian), alongside the original monolingual (English-only) version of the test. A comparison of the bilingual…

This paper presents evidence that supports the valid use of scores from fully automatic tests of spoken language ability to indicate a person's effectiveness in spoken communication. The paper reviews the constructs, scoring, and the concurrent validity evidence of "facility-in-L2" tests, a family of automated spoken language tests in Spanish,…

Discusses how to tackle the problem of determining a meaningful score for yes-no tests used to measure the size of receptive vocabulary. Signal Detection Theory is applied, and a new more accurate index is suggested. (Author/VWL)
