Vocabulary knowledge is regarded as the best predictor of proficiency in second language acquisition. Receptive vocabulary in International Baccalaureate (IB) institutions is learnt implicitly through a language and literature programme, as the deliberate teaching of the lexical aspect is not a priority. Thus, the main aim of this study is to ascertain the receptive vocabulary knowledge of primary and secondary school students attending an IB school by means of the updated Vocabulary Levels Test. 339 students from 7th to 10th grade were assessed with said test in a single invigilated session. This test measures knowledge of the first most frequent 5000-word families of the English language, which represent roughly more than 95% of any text. The results showed that the first 2000-word families (frequency bands 1 and 2) proved to be highly known by the participants, whereas the third 1000, the fourth 1000 and the fifth 1000-word families (frequency bands 3 to 5) need improvement. These findings align with the prevailing trend of implicit vocabulary acquisition observed in this school. Boosting vocabulary learning by a more explicit teaching approach would greatly benefit learners, especially focusing on the third, fourth and fifth frequency bands.
