Students and professionals use OI Digital Institute

The level of teaching, experience and patience from the course providers was absolutely incredible. It was intense, there was a lot to learn in a short space of time, but it was structured to ensure it was taught and consumed at an attainable pace. It was extremely rewarding.
Dan Parkinson
I enjoy studying with my classmates, because we make progress together, give feedback together, and have made good memories. The teachers are also very good, they take good care of our study and life, and give us good guidance.
Zheng Langxing
My experience in the OPSE course was amazing. Also, I am grateful to the teacher for her efforts and how she made my journey unbelievable. I improved in many aspects and I learnt many things. Moreover, I feel so satisfied and happy about how the school helped me to achieve my goals
Said Almamari
I now feel confident and capable to teach not only in person but in online spaces thanks to their guidance. I highly recommend the Trinity CertTESOL through the OI Digital Institute!
Leane Meiring
This course helped to systematise my knowledge of English grammar and phonology as well as gave me some important tips on the teaching methods and techniques. The most valuable tip was how to maintain the balance between student talking time and teacher talking time. Might sound easy, but it's not!
The tutors support was excellent, both Jane and Lenka put a lot of effort and created the most welcoming atmosphere with very interesting input sessions, provided detailed guidance and support with the lesson planning, demonstrated delivery of high-quality lessons & gave very personalised feedback.
Alyona Jasper
The tutors were very supportive and encouraging at all times throughout the course, which really helped me get through this super-intensive 4 weeks. Thank you so much, Lenka, Jane and Amanda! The qualification has given me more options and confidence in looking for TEFL jobs around the globe.
