My life and classrooms will never be the same since meeting those inspiring people from iTDi. I am blessed to have the opportunity to develop myself and my teaching skills. I have opportunities to chat with other teachers.

I'm really grateful to find a such supportive community with quality materials to develop teachers language and teaching skills. Through their example, I also learned how to give back to the community and to support teachers like me in their own development.
