FAQ
Frequently Asked Questions
How is doing teacher coaching different from TEFL/TESOL/CELTA certification?
Certifications like TEFL, TESOL, and CELTA give you the theory and structure, but coaching is where you apply it, grow confidence, and sharpen your real-world classroom skills. Language Flex coaching is personalised, practical, and focused on helping you thrive in actual teaching scenarios, whether online or in-person.
I don’t have my TEFL/TESOL/CELTA certification. Can I still teach?
Yes—especially if you’re working independently or online. Many platforms and students prioritise teaching ability and communication skills over formal qualifications. Our coaching helps you get classroom-ready, even without certification, by focusing on lesson delivery, student engagement, and effective teaching strategies.
I have my TEFL/TESOL/CELTA certification, but could use some help or a refresher. How does teacher coaching help?
Great! That’s exactly where coaching shines. We help you bridge the gap between training and teaching—polishing your lesson planning, improving classroom management, and giving honest feedback on your delivery. It’s like a personal trainer for your teaching career.
I’m considering getting my TEFL/TESOL/CELTA certification. Are all certifications equal? What do you suggest?
Not all certifications are created equal. Some are intensive and internationally recognised (like CELTA), while others are quicker and more flexible. We’ll help you understand your goals and recommend the best route based on where, how, and who you want to teach. Book a free consult—we’ve been there.
My school has great teachers, but we could use some new techniques to upskill our team. How can you help?
We offer tailored professional development sessions for schools and institutions—covering areas like student engagement, task-based learning, feedback strategies, and digital tools. We make the training practical, interactive, and immediately useful in the classroom. Let’s level up your teaching team together.
TESTIMONIALS
What Our Students Say
Karen is a great teacher with a wealth of knowledge and excellent communication skills. She helped me enormously with my teaching, instilling confidence and inspiration. She is highly professional and was very well prepared, bringing new ideas and helping reshape old ones. She is very generous with her time and makes everything easy. I value her lessons a lot, and have already implemented her strategies into my teaching – with very visible and positive results. I would recommend Karen to anybody looking to improve their teaching ability.

Karen was an incredible teaching coach. She’s a mentor, but also a friend and colleague. She will go above and beyond for new teachers and ensure they have the tools and resources they need to succeed. I really enjoyed having her as a teacher trainer!

Karen is an excellent teaching coach. She knows what makes a class work, and is able to infuse that knowledge into personal mentorship that enables the trainee to optimalize their own personality and teaching style. She is an excellent communicator and a visionary.
Tori Gleason
Teacher / June 2025
Karen Wilke gave 110%, always providing plenty of office hours, very helpful feedback, advice, and access even when office hours were over. Karen had the perfect mix of being an expert in the field of TEFL, while also having a wonderful energy and sense of humor. Karen took a subject that could have been very dry and made it exciting, inspiring, and something I looked forward to learning every day. I can’t say enough kind words about my experience in this class.
