About the teacher training centre

Do you want an online professional development course, no matter where you are in the world?

The IH Online Teacher Training Institute (OTTI) is the teacher training wing of International House World Organisation. We provide online professional development courses for EFL teachers around the world. We have courses for every stage of a teacher’s career, from soon after your initial qualification to DELTA level and management courses.

Learning online gives you the flexibility to set your own study hours and save money on travel and accommodation.

On our courses you can ‘attend’ whenever (and wherever!) is convenient for you. You don’t usually have to attend a live chat or webinar at a specific time, although sometimes there are live “meetups” so you have the chance to chat with your tutor and other classmates.

To help you there is ongoing support from your tutors in online forums and through individual feedback – and you’ll probably find your other course participants are really helpful as well. You are definitely not studying alone, and this tutor and peer support is what our trainees say they like most about our courses.

Bydgoszcz’s architecture is beautiful and eye-catching with magnificent historical buildings. We have a theatre, philharmonic, opera and cinemas.

I have to admit that my expectations before coming to IH Cairo were quite low. I was totally shocked by the quality of the organization and the preparation of the teachers. I was completely surprised at the increased recognition of IH Cairo among international students.

At IH Cairo the staff and teachers are very helpful and knowledgeable. They assist students through each stage of the program. I love coming to IH Cairo because I always feel welcomed and excited for class.

Peter G.

It was great to stay in the Akcent IH Prague accommodation. Living with other people form the course meant we could help each other with lesson plans in the evenings but we were also able to hang out together socially.

H. Hamill

I was thoroughly engaged and highly stimulated intellectually by this course. Everything about the course, from the tutors to the facilities, was top-notch. I left with a feeling of immense satisfaction due to the challenges faced and overcome while on the course. I left also with knowledge that will act as a steadfast foundation for my future career. The course has set me up on track to pursue a rewarding and valuable career by giving me the toolkit that I will need to do this. By taking this course I have also discovered the path that I will need to stay on if I wish to make my dream of becoming a good teacher a reality.

Cherry

I really appreciate what I learned from all the trainers and peers on the course. I did both the CELTA course and CYLT course at IH Bangkok, after which I couldn’t even believe myself for being professional in teaching in almost all aspects. Once I step into the classroom, I know what I should do with my lesson materials, I aim to achieve in my lesson, I can do better for next lessons. Thanks to all the tutors who helped us and gave all their best during the courses.

Preeti

The CELTA course I took over the summer was run online, and being online did not take away from the excellence of the course. The course encourages teachers to teach real students in a student centred way, thus making the experience very authentic. All in all, it is very intense but well worth the money spent.

Sofia Caprarulo

It was both challenging and informative. The course gave me the opportunity to learn many new ideas and strategies, to develop and improve my teaching, and connect with wonderful teachers from around the world.

Maria M

As a CELTA graduate, I can tell you that the course at IH Rome Accademia Britannica is the best professional decision that you could make. It will fundamentally change your approach to the classroom forever. You will encounter supportive tutors and experienced mentors that will help you unlock all your teaching potential. Together with other eager trainees you will learn how to manage the classroom successfully, engage with students effectively and to take with you all that you need.

Paola B

I simply loved the CELTA Online with IH Rome and my great and professional tutors, Flo and Chris: they were supportive, providing constructive, accurate and punctual feedback for each of our activities. It was a challenging and yet unforgettable experience.
