This presentation introduces https://vocableveltest.org/ which was designed to help teachers and researchers estimate Japanese university learners’ vocabulary level and vocabulary size, while overcoming the limitations of the existing vocabulary level and size tests. Teachers can create online vocabulary tests based on various (1) lists (BNC/COCA, NGSL, TSL, AWL, NAWL, JACET, SUBTLEX, SKEW-J), (2) word counting units (lemma, flemma, word family), (3) band sizes (100, 250, 500, and 1000 words), and (4) sampling ratios (5/1000 to 100/100). Tests can be either form-recall (L2 to L1) or meaning-recall (L1 to L2) translation tests. Meaning-recall tests can be written or spoken receptive tests. Teachers can also create pre-and post-tests from over 7000 items. Teachers can choose to provide learners with feedback on incorrect items or not. Learners receive a profile of their lexical knowledge, while teachers can view the lexical profile of each student and class mean lexical profiles. Teachers can download automatically marked responses, typed responses, and the time taken to complete responses. An extensive bank of possible answers yield automatically marked responses. Incorrect responses are inspected, and valid meaning-recall answers are added to banks of correct answers. While valid, but none target form-recall responses result in learners receiving a further 30 seconds to respond. The purposes of the tests include (a) establishing a learner's lexical mastery level that can be used to match learners with lexically appropriate reading materials, and (b) separating learners based on their lexical knowledge that can be employed when reading, listening, or writing.
