The theoretical model of communicative competence underpinning the CLB is also reflected in PBLA:
Communicative competence requires organizational knowledge, including grammatical and textual knowledge; pragmatic knowledge, including functional and sociolinguistic knowledge; and strategic competence (CCLB, 2012a, p. IX).
Through instruction and assessment, teachers aim to address and have learners practise language learning activities related to each of these elements.
