1. What is VocabLevelTest.org?

VocabLevelTest.org provides a non-commercial platform for English language teachers and researchers to create and administer vocabulary level tests, and to freely share the anonymized results of those tests for the benefit of the English language teaching and testing community.

Our aims are:

  • To provide self-marking standardized vocabulary tests, including:
    • meaning-recall (L2 to L1 translation) in reading and listening modes
    • form-recall (L1 to L2) in typing and speaking modes
  • To help teachers identify which words their learners should spend time studying, and to match learners with materials of an appropriate level
  • To develop freely available difficulty ranked wordlists
  • To allow researchers to compare the results of vocabulary levels tests across studies consistently and reliably

Please note that the site is current in BETA status, which means some functionality is still being developed and improved.

2. What do vocabulary levels tests measure?

Vocabulary levels tests measure the extent to which the test taker can recall the meaning or produce the form of items appearing on the test. If a test taker can correctly recall the meaning or produce the form of a target item, they are deemed to "know" that word for the purposes of language teaching and research.

Items appearing in vocabulary levels tests are drawn from frequency bands, i.e. ranges of words which normally cover 100, 500, or 1000 items. Not all of the items appearing in the designated bands are included in the test; only a representative selection of words are included (typically 30 items per 1000 item band, or 3%). A student is deemed to have mastered a band when they have correctly responded to at least 98% of the items sampled from that band.

The bands of words themselves are drawn from wordlists, which are comprised of the most frequent words of the target language as a whole. The New General Service List (NGSL), which is one of the wordlists utilized by vocableveltest.org, covers 92% of the words appearing in general English texts.

3. How can the results of vocabulary levels test help teachers and researchers?

Teachers and researchers use vocabulary levels tests to estimate the percentage of words learners know. Once this information has been established, it can be used to inform decisions about which materials to assign to students for language study purposes.

It is well established in the research that non-native English readers need to know at least 98% of the words in a text to be able to understand it without constantly looking up the meanings of the words in a dictionary. This level of unaided comprehension is necessary to engage in activities such as extensive reading and task-based learning.

The following conditions must be met in order for the results of a vocabulary levels test to be valid:

  • The wordlist used by the test must be an accurate representation of the target language
  • The word counting unit must be an accurate representation of learners' ability to comprehend inflectional and derivational forms
  • The test items selected from the bands must be an accurate representation of those bands
  • The question format must be an accurate representation of how the meaning of words are recalled when reading and listening, or how the forms are recalled when writing or speaking

This site endeavors to meet these conditions in order to ensure that the results of the tests it provides are valid, reliable, and useful.
