What opportunities does a TESOL certificate give a teacher today and how does TESOL, TEFL, TESL differ.
Free consultation






English teachers for foreigners are in high demand worldwide. The profession is not limited to native speakers; proficient English speakers can also pursue teaching opportunities abroad.
However, fluency in English alone is not sufficient for teaching others — knowledge of effective language teaching methods is essential. Consequently, numerous courses have emerged to provide at least minimal training for a large number of teachers. These courses offer certificates upon completion, which are often required when applying for teaching positions abroad.
When a job vacancy abroad specifies a requirement for a TESOL certificate, it means exactly that.
TESOL stands for Teaching English to Speakers of Other Languages. It is a certification program designed for English teachers who instruct non-native speakers. To obtain a TESOL certificate, one must enroll in a course that covers teaching methods offered by educational organizations. Although there is no universal course standard or TESOL certificate, the CELTA and Trinity TESOL are widely recognized variants.

In addition to TESOL, other abbreviations like TEFL and TESL are commonly mentioned in teacher requirements. They represent different types of certification for teaching English as a foreign language, each with their own characteristics:
Although TESOL and TEFL are often used interchangeably, there are distinctions. It is advisable to choose certification based on the desired country of employment and employer requirements. For instance, TEFL / TESOL certificates are in demand in Asian countries like China and Thailand. It is crucial not to confuse TESOL certification with master's programs in teaching English to foreigners, such as a Master of Arts in TESOL.
Employers abroad usually require a TESOL certificate. Job postings may state "TESOL / TEFL certification or equivalent required". Additionally, a certificate may be necessary for obtaining a work visa in certain Asian countries.
In some cases, certificate legalization at the embassy of the country where the course was taken is mandatory. The embassy must be located in the country of employment. For example, if a candidate is planning to work in Thailand and needs to legalize a British TESOL certificate, they should contact the British Embassy in Bangkok.
A TESOL certificate can be earned by completing a specialized course, either:
The final grade for the course is determined by assessments throughout, including written work and practical performance. This grade serves as the basis for certificate issuance.
TESOL courses face a significant challenge: the absence of a governing body that establishes consistent standards and oversees all English teaching methodology programs for foreigners. As a result, these courses are proliferating rapidly, and the quality of some, as well as the value of the certificates they provide, are questionable.
Compounding the issue is the demand for subpar certificates, as certain foreign employers, particularly in Asian countries, accept them merely as formalities. This has led to the rise of "courses" that can be purchased cheaply through coupon websites and completed within a few days.
Some even offer paid services where someone else takes the TESOL / TEFL courses on behalf of the individual, providing pre-made "certificates." Clearly, such certificates hold no value in either case.
So, what should someone do if they seek a reputable course that offers real learning opportunities and enhances professional prospects? There are two options:
| TESOL certification | Governing body | Duration | Cost | Validity |
|---|---|---|---|---|
| TESOL / TEFL | Depends on course | 1+ months | 250 USD | Partial |
| CELTA | Cambridge CELA, Great Britain | 4–5 weeks | 2,000 USD | Worldwide |
| Trinity CertTESOL | Trinity College London, UK | 5 weeks | 1,200 USD | Worldwide |
When opting for TESOL / TEFL courses, the ideal choice is to immerse oneself in an English-speaking country to fully experience the language environment. Moreover, courses in these countries are somewhat regulated by the government.
Alternatively, courses offered in your own country can be more affordable.
Lastly, online courses provide the most budget-friendly option, offering flexibility in class scheduling and the ability to take a foreign course from the comfort of home.
However, online courses have a noticeable drawback: the quality of online interaction with participants and teachers cannot match that of in-person classroom presence and hands-on teaching practice under the guidance of professionals.

|---|---|---|---|---|
| 150-hour Master TEFL TESOL course | Great Britain | TEFL TESOL Certificate | 195 USD/course | up to 6 months |
| TESOL Certificate Coursera | USA | Arizona State University | 50 USD/month | 5 months |
| Online Premier TEFL Course | Great Britain | TEFL Organisation Ltd | 391 USD | up to 6 months |
