  • Q: How do I know which TEFL provider to use?

    With so much choice and a huge amount of information online, navigating the world of TEFL courses can be a tricky place and it can be difficult to know which TEFL certification is best for you.

    Firstly, you’ll need to make sure you choose a TEFL course provider who’s internationally recognised and is regulated by a governing body. This ensures the training you receive is of the highest quality and your TEFL qualification will be highly regarded and accepted by employers worldwide. All of our TEFL courses, online and combined, are regulated by Ofqual, the UK Governing body responsible for monitoring TEFL qualifications. Not only that, but we’re also accredited by ODLQC. If you want to find out more about what this means, we have lots of information you can access by clicking here.

  • Q: Where are your combined TEFL courses held?

    Our combined TEFL courses are the perfect blend of flexible, online learning and practical, face-to-face training. The practical training takes place in one of our 30+ locations around the world in the UK, South Africa, the US and the Netherlands – you can view the full list of locations here. In most locations, we run our classroom TEFL courses once or twice per month, so you can either choose a weekend that suits you or enrol using our flexi option, which means you won’t commit to a date straight away, you can let us know when you’d like to attend in the future.

  • Q: Do I need to know English grammar and grammatical rules?

    Our TEFL courses are designed for those who haven’t studied grammar since they were at school (most of us)! It’s not everyone’s favourite subject, but if you’re a native English speaker, you already have a natural understanding of grammar – it’s all about turning that knowledge into teachable rules – that’s where our TEFL training comes in!

    So, whether you’re a native speaker or simply fluent in English, our TEFL courses will help you feel totally confident when it comes to taking your first grammar class.

  • Q: Who can I teach when I am TEFL qualified?

    With all our TEFL courses, both online and combined, you’ll be qualified to apply for TEFL jobs abroad or to teach English online, to adults and children of any age. When you choose to study either our Online TEFL Course (180 Hours), Online TEFL Diploma (300 Hours) or Online TEFL Advanced Diploma (420 Hours), you’ll get access to our specialist TEFL courses, which are super handy if you want to be TEFL trained in a particular area.

    Our Level 5 courses (180/300/420 Hours) contain specialist modules. the more advanced the course, the more modules are included, this will make you more employable and allow you to earn more!

    Some of the specialist modules we have include: How to Teach Young Learners, Teaching One-to-One & Online, How to Teach Business English, Teaching IELTS (International English Language Testing System), and Teaching Other Subjects in English. These will prepare you for specific teaching situations. Plus, being qualified in specific TEFL areas will increase your earning potential!

    We are the only TEFL provider to offer these Specialist Courses at Level 5 and Advanced Level 5, which will make your CV stand out to future employers. If you’ve opted for one of our Level 5 TEFL qualifications, you’ll naturally have a greater pick of TEFL jobs on offer as you’ll be qualified to a higher level than if you choose a Level 3 course.

  • Q: Are there any age restrictions?

    No, there are no age restrictions to enrol onto any of our TEFL courses! We often get asked “Am I too old to TEFL?” Our answer: definitely not! We’ve trained teachers of all ages that have built successful TEFL careers, both online and across the globe. Check out some of their stories here!

  • Q: Do I need to be a native English speaker?

    You don’t need to be a native English speaker to take a TEFL course, but you do need to have a native English speaker level to succeed. If you aren’t a native English speaker, we recommend you opt for our 120 Hour TEFL course (you can always upgrade later), unless your standard of English is near-native.

    If you want to chat to one of our friendly TEFL experts to figure out which TEFL course is best for you, then you can request a call back.

  • Q: Do I need any qualifications to take a TEFL course or diploma?

    The short answer is no! You only need to be able to speak English fluently to take a TEFL course or diploma – we’ll train you on the rest. Don’t worry if you don’t have a bachelor’s degree, this isn’t a requirement for any of our qualifications and you can teach English online and abroad without one. If you don’t have a degree, our advice would be to take our Online TEFL Diploma (420 Hours) to boost your employment potential and give yourself the best chance of bagging a great TEFL job!

  • Q: How can I improve my job chances with this course?

    We also have a range of specialist courses that could help expand your skills even further so you’ll stand out from the crowd.

    Another way to add extra kudos to your CV is by adding a 20 Hour Practical TEFL Course – this will provide you with face-to-face practical learning in the classroom.

    We’ve also taken our 300-hour course and combined it with either a digital marketing or technology course creating what we’re calling our TEFL Plus range – these courses will be great if you’re considering becoming a TEFL freelancer or are even considering a different career route after TEFL.
