120-hour TEFL course
120 hours is the industry standard. This is the minimum you should have if you want to teach English abroad or online. If you’re a native English speaker, have a degree and/or some previous teaching experience then this should be sufficient for securing work.
A 120-hour course can be completed entirely online or, if the provider offers it, include some in person classroom training.
Level 5 TEFL course
A Level 5 TEFL course is one that is Ofqual-regulated and has been assessed to be a level 5 qualification according to their framework. These courses are typically more than 120 hours and, like a 120-hour course, can be taken entirely online or combined with classroom training.
Level 5 training can help give you a slight edge when applying for jobs, particularly for those without a degree, previous teaching experience, and those who aren’t native English speakers. As a more comprehensive course it’s a great option for those who don’t feel very confident about teaching. It’s important to note that it won’t get you a better paid job - salaries in the TEFL industry depend on experience - but it can make it easier to secure work by making your CV stronger.
CELTA
The CELTA is one of the most well-known and established courses for teaching English as a foreign language. It focuses specifically on teaching adult learners.
CELTA courses are run through approved centres and typically involve a month of full-time in-person study and includes 6 hours of observed teaching practice. This course costs upwards of £1,200 so is considerably more expensive than a TEFL course, but can be a good investment for teachers who are serious about making TEFL a career and working their way up the ladder. It’s common for teachers to do a TEFL course first and a CELTA at a later date once they’re sure teaching is for them.
Trinity CertTESOL
The Trinity CertTESOL is very similar to the CELTA in how it’s delivered. Like the CELTA, it’s an intensive 4-week course that includes observed teaching practice. Choosing between the CELTA and Trinity CertTESOL can come down to what is held in a more convenient location for you and price - the Trinity CertTESOL can be slightly cheaper.
Advanced courses
Advanced TEFL courses focus on specific areas of TEFL. These courses can be added on after completing your initial qualification, whether that’s a 120-hour course, Level 5, or CELTA.
Common advanced TEFL courses focus on areas such as Business English, teaching English Online, teaching young learners, and exam preparation. Developing a niche in the TEFL industry can be key to success and higher wages, so an advanced course is a good place to start.
