How iTDi Works
Simple. Human. Effective.
iTDi strips away the noise and gets back to what teachers actually need: great instruction, real peers, and room to reflect.
Choose your course
Do you want to dive deep into theory? Challenge your thinking? Gain skills you can bring back to your classroom? Learn skills to advance your career? Find the course that best suits your goals.
Learn in a small group
Live courses are intentionally small, so you get real attention from the instructor and genuine connections with teachers worldwide. Meet for weekly live sessions (or watch recordings) and discuss in a private forum.
Lead in your classroom
Challenge your teaching beliefs, acquire practical skills, and leave with ideas you can use on Monday morning — not just theory. iTDi Connections continue long past the end of your course.
The iTDi Difference
It's not just the courses.
It's not just the courses.
It's the people.
Most professional development leaves you with a certificate and a folder of slides. iTDi gives you something more lasting: a real community of teachers who get what you do, where you struggle, and why you care.
Our courses are built around conversation, reflection, and genuine connection — because the best teaching insights come from talking with other teachers, not just listening to lectures.
Private course forums
Discuss ideas, share resources, and support each other between live sessions.
Truly global perspectives
Connect with teachers from over 80 countries. Diversity of context is part of the curriculum.
Built by teachers, for teachers
iTDi is a social enterprise. Our mission is teacher wellbeing and growth — not profit.
"What makes iTDi different from other organizations is that you feel like you are in a community. The courses were very interesting — not just the material, but actually attending sessions with people from far, far away."
"My life and classrooms will never be the same since meeting those inspiring people from iTDi. I have opportunities to develop myself and connect with teachers worldwide."
"I'm grateful to find such a supportive community with quality materials. Through their example, I also learned how to give back and support teachers like me."
