What Our Students Say

  • Marissa

    Everything you need

    5 stars "I highly recommend the 120hr Dux TEFL/TESOL course. It's short, comprehensive, elaborate but not to an extent that seems redundant. It takes a practical approach and it includes various tips for new teachers. As a new teacher, Dux has equipped me with valuable knowledge on not only how to plan successful lessons but how to keep my students and their language goals in mind, while tending to their need and ability to feel accomplished while reaching them!"

    5 stars "I just completed my 120 hrs DUX TEFL course and I am super excited! It gives confidence in teaching- listening, reading, writing and speaking; lesson planning. The end of unit tests are fun. It´s clear and easy to use. It is flexible. I would highly recommend it."

    The Dux TEFL/TESOL course was very informative and easy to grasp. Great for new teachers!

    5 stars "The Dux TEFL/TESOL course was very comprehensible and the information was well spaced out. As someone who is at the beginning of her teaching journey, I went in knowing absolutely nothing and wondered if I would be able to understand and fully grasp all the information. Luckily they managed to explain all of the jargon well and they provided me with lots of tools that I can use to formulate my own teaching style and lesson plan. I am grateful for the new confidence I now have in being able to do well as a teacher and I no longer feel like a fish out of water. Thank you DUX!"

    User friendly experience

    5 stars "I found the DUX platform to be intuitive and user friendly. The lesson content was written well, applicable to the course objectives and easy to digest. My only critique would be that I sometimes disagreed with the way some of the multiple choice questions were phrased or structured. But I guess the academic in me always likes to debate things. I have not applied for teaching positions with my new qualification yet so I don't know whether employers recognise DUX. Overall it was a quick, easy and painless experience."
