This single module program of study is recommended for English learners who may only need to complete a single CEFR level towards a certification program, or who may want to study for one level at a time. Each level takes approximately 40 hours of study time to complete. Successful completion at each level means learners will earn a Certificate and 4 Continuing Education Units (CEU’s). Successful completers will receive all data validating their credentials in a personal blockchain-secured digital wallet.
