I can't imagine a more superb on-line training program for TEFL. No wonder this organization is so widely recognized and accredited! The teachers are excellent, know their material well, are very responsive and exercises are always marked within time frameworks named. The course materials, quizzes and exercises really make sure one has learned the material. Most of all, the methodology of the teaching is so much more effective than anything I or most people will have ever experienced in school. Finally, the ongoing resourcing of their teachers with upgrading courses and materials is a huge bonus. A superb organization and program. I cannot imagine it better!!
