  • 120 hours split into five clear modules, including 20 hours of video observation and 10 on teaching online
  • Six months to finish, with paid extensions from one week to three months
  • Lifetime access to the TEFL Jobs Centre
!Watch out for
  • A standard 120-hour certificate, not a Level 5 qualification
  • No live practice teaching real students in the online-only course
