If teaching English is on your radar, learn about what a TESOL certificate is and how it can help you in your career as an educator.

What is TESOL?

TESOL, or Teaching English to Speakers of Other Languages, is a qualification that helps teachers understand how language and culture interact with one another. It also teaches you how to teach — many English speakers instinctively know how to use grammar and vocabulary properly but may not be able to explain why or when to use it. This is where TESOL training comes in. Schools worldwide rely on TESOL-certified teachers, and it's a trend that is only increasing.

What is the difference between TEFL and TESOL certificates?

The world of teaching English is filled with a ton of sometimes confusing acronyms. When you’re looking for a certificate to teach English, you will likely come across these options:

  • TESOL: teaching English to speakers of other languages. TESOL is geared toward students learning English in an English-speaking country, but it can also be used abroad.
  • TESL: teaching English as a second language. TESL is a popular acronym in Canada and focuses on teaching learners in a native English country. Like TESOL, this certificate can also be used abroad.
  • TEFL: teaching English as a foreign language. TEFL courses focus on teaching learners in a country where English is not the native language.
  • CELTA: Certificate in Teaching English to Speakers of Other Languages. Cambridge English awards CELTA certificates. Courses are offered through recognized training centers. CELTA certificates can be used to teach learners in both native and non-native English countries.
  • Trinity CertTESOL: The CertTESOL is awarded by Trinity College London. Courses are offered through recognized training centers. Trinity CertTESOL can be used both at home and abroad.

The truth is, the differences between the English language teaching certificates are subtle. Usually, all certificates can be used to get jobs both in your home country or other countries where English is spoken as the primary language as well as abroad.

You don't need a degree to get TESOL certified, and earning a certificate is an excellent way to enter the language teaching industry without a degree. However, a degree will provide better access to job opportunities and allow you to progress faster.

While there’s no strict academic framework to follow when entering the ESL field, it is often helpful or essential to have a bachelor’s degree. In many popular countries to teach English, job opportunities list a teaching qualification – TESOL/TEFL – and a bachelor’s degree in order to teach and get approved for a visa.

What are the benefits of getting TESOL certified?

Getting TESOL certified comes with numerous benefits. Some of these include:

  • Valuable skills are added to your resume. Showing employers that you have formal training is a testament to your expertise and dedication to the field. If your course includes live teaching practice, this also demonstrates experience working with students which is especially useful for new teachers.
  • You can gain a competitive edge. Since most employers prefer or require that their English language teachers have a teaching qualification, having a TESOL certificate will increase your chances of being hired over other candidates who don't have one. This is especially important if you're looking for work in international schools or private language institutes where the competition for jobs is fierce.
  • You may be eligible for promotions and higher salaries. In some countries, teachers are compensated more based on their qualifications. Having an accredited TESOL certificate could land you a higher-paying job or promotions that come with a better salary.
  • You open yourself up to an international career. Teaching English abroad is popular across the globe. Teaching ESL provides a fantastic opportunity for travelers who wish to live and travel abroad while earning money at the same time.
  • You’ll be more confident in the classroom. TESOL certificates teach you how to teach. You’ll not only learn how to teach more abstract grammar topics but you’ll be instructed on how to assess students and manage behavior.

If you were unsure before, the above points show that getting TESOL certified is worth it!

How much does a TESOL certificate cost?
