I would recommend that every TEFL student attend one of these courses, as the practical experience in the classroom is invaluable. The course cements the course theory material. Even experienced teachers or industry type trainers would benefit from the classroom course, as teaching English the TEFL way is quite different to their type of teaching.
I would also recommend students to attend the classroom course early on in their overall course, as going through the PPP and the Planning stages will help greatly in understanding the theory.
An excellent course delivered beautifully and expertly.
