Best TEFL Certifications Online to Kickstart your ESL Career

Choosing the right TEFL course can be a headache.

There are hundreds of TEFL providers claiming to be the best. In fact, it would take days of research and review-reading to decipher the good from the bad.

So we've done the hard work for you and compiled a list of the best - and most affordable - TEFL certifications online. This means every course we've listed is accredited and internationally recognized, so you can get hired as an ESL teacher anywhere.

Most of the TEFL providers we list also have job placement services for their students, which can help you land your first ESL job after you complete your course.

Why being TEFL certified matters

ESL teaching has become increasingly competitive. The freedom to work from home or travel is alluring to most people and ESL provides that freedom. However, most English teaching companies require teachers to hold a TEFL certificate as a standard qualification, while degree requirements tend to vary between companies.

In my experience, holding a TEFL certification and a little experience is enough to land almost any ESL job - even if you don't have a degree. For those looking for higher pay or advanced teaching positions, specialty ESL courses are a great route to go. For example, being armed with both a TEFL and IELTS certificate can really show your employer your dedication, experience, and commitment to teaching.
