“I was very pleased with the whole experience. The grammar and phonology modules were great in-depth reviews. The methodology module was an excellent step-by-step guide of how to plan a lesson. I have a better understanding of how students learn and feel much better prepared now to teach English in the United States.

My tutor, Aaron Marques, gave very insightful comments from his personal teaching experience. He was a great tutor, always responded quickly. He really made the program! OnTESOL was a great TESOL certification course that gave me the flexibility to study from home and set my own hours”.
