What's the Difference Between CELTA and TEFL?

Curious to know what the difference between CELTA and TEFL is? Spoiler alert: they are the same! Read on to understand why the Cambridge CELTA is a specific type of TEFL certificate.

Key takeaways 🔑

  • CELTA stands for Certificate in English Language Teaching to Adults (now known as Certificate in Teaching English to Speakers of Other Languages) and TEFL stands for Teaching English as a Foreign Language.
  • TEFL refers to any certification program that trains an English speaker to teach their language to others. CELTA, on the other hand, is an intensive ESL teaching certificate, designed by Cambridge University. It is considered one of the most prestigious qualifications for teaching English abroad. You can also think of CELTA as a brand of TEFL.
  • Price is often the deciding factor for students who opt for a TEFL certification other than a CELTA. Due to the prestige of the program, obtaining your CELTA can cost anywhere from $1,500 to $4,000, depending on the school. TEFL courses, meanwhile, can cost anywhere from $200-$2000.
What's the Difference Between CELTA and TEFL?

It’s perhaps no surprise that one of the most popular jobs for native English speakers abroad is teaching their mother tongue, but choosing a certification for this career option can make it feel like you’re drowning in a veritable alphabet soup of acronyms: TEFL, TESOL, TOEFL, TESL, CELTA… How are you to know the difference and, more importantly, how are you to know which one is right for you and your career?

When I was 22 years old, I decided to become certified to teach English after having finished my undergraduate degree. I had been living in France for two years and had recently spent time living in Spain. My intention was to complete my training before moving to Argentina to teach English, but I wanted a certificate that would be recognized should I decide to return to Europe – or even go to Asia!

I knew that I wanted to commit to a program full-time, but the question was which one to choose?

When it comes to choosing between TEFL and CELTA, the first thing to know, right off the bat, is what these acronyms stand for:

  • TEFL: Teaching English as a Foreign Language
  • TESOL: Teaching English to Speakers of Other Languages
  • TESL: Teaching English as a Second Language
  • CELTA: Certificate in English Language Teaching to Adults (now known as Certificate in Teaching English to Speakers of Other Languages)

While at their roots, each of these acronyms means something slightly different, in practice, the first three are often used interchangeably to refer to any certification program that trains an English speaker to teach their language to others. CELTA, meanwhile, is the name of a very specific one of these programs sponsored by Cambridge University; think of CELTA as a brand of TEFL, TESOL, or TESL program (which, for the sake of succinctness, I’ll refer to as “TEFL programs” here).

Because any school offering the CELTA must adhere to strict standards and employ teachers that have been certified by Cambridge, it is often perceived as being the most prestigious of all TEFL program options -- in fact, you’ll sometimes see job offers for English language teachers citing the CELTA specifically as a prerequisite to be hired.

That said, CELTA is far from the only worthwhile TEFL certification. Many other programs offer equivalent standards -- and some even go above and beyond a CELTA course. The main difference is that while with a CELTA, the quality of the course you’re paying for is pretty much guaranteed, with a TEFL, you’ll need to do a bit more research to make sure the program is offering what you’re looking for.

To help you decide which one is right for you, let’s break down the difference between CELTA and other TEFL programs.

What's the difference in length? CELTA vs. TEFL

CELTA requires students to complete 120 hours of class time and six hours of student teaching (practicum) with real ESL learners. Most CELTA courses are offered on a full-time basis and take four weeks to complete, but some CELTA schools offer part-time CELTA certification, which can be completed in up to three months.

TEFL programs vary greatly: they can be as short as one intensive weekend, or about 20 hours of class time, and as long as several months, with up to 300 hours of class time.

The duration of the program will certainly be a factor in deciding which course you take, but bear in mind that however long it takes you to earn your certificate, a worthwhile program will require at least 100 hours of class time (completed on-site or online) and at least six hours of teaching practice before awarding you your certificate.

What's the coursework like? CELTA vs. TEFL

Most CELTA courses require students to attend the full-time, month-long course, which means six-hour days and a heavy homework load, including lesson planning for your practicum and four written assignments. A month-long CELTA program, then, is a full-time commitment. It’s tough to do much of anything else (including getting much sleep) during your CELTA.

Even as a part-time student, a CELTA certification is quite intense, as the coursework assumes that participants already have a firm grasp of English grammar concepts, something that’s not a given even if you’re a native speaker of the language. If this is not the case for you, you may need to do supplementary work while completing the CELTA course.

TEFL courses range in intensity; some are completed at least in part online with class time relegated to weekends, which can give students the flexibility to continue working while completing the course.

Some TEFL courses also don’t require students to complete their practicum with actual English language learners, but choosing this type of course can be problematic: not only is working with actual students an important part of learning to teach, but many potential employers around the world will not accept anything else – such as teaching practice with fellow student teachers standing in for ESL students – as a valid practicum.

What's the difference in cost? CELTA vs. TEFL

Price is often the deciding factor for students who opt for a TEFL certification other than a CELTA. CELTA can cost anywhere from $1,500 to $4,000, depending on the school. This is in part because of the prestige of the program: it is recognized internationally, and schools hiring teachers know exactly what the program entails. In addition, because not everyone who attempts the CELTA achieves the certification, if a person looking to hire a teacher sees the CELTA on someone's CV, not only does the person know what the prospective teacher has been taught, he or she also knows that the teacher has succeeded in completing the rigorous coursework.

TEFL courses, meanwhile, can cost anywhere from $200-$2000. While some TEFL courses are just as expensive as CELTA, the vast majority are not, making them a far more attractive option from a financial perspective. In particular, online TEFL courses typically have a very reasonable price tag.

What's more worth it? CELTA vs. TEFL

While the price of a CELTA tends to be steeper than that of another TEFL certification, it may be worth it. Here are some reasons you may want to opt for a CELTA, in spite of the price:

  • It’s internationally recognized, which grants CELTA-holders access to jobs that someone with a lesser-known accreditation wouldn’t be eligible for. Even if jobs are ostensibly open to people with any TEFL certificate, a holder of a CELTA may have their application sent to the top of the pile.
  • It’s externally assessed, which means that if you don’t have a ton of time to research the validity of different TEFL certificates, it’s a safe and sure bet.

That said, here are a few instances in which a CELTA may not be the right choice for you:

  • If you’re hoping to work with children. CELTA is explicitly designed for teaching adults, so another TEFL certificate might be better if you hope to work with kids or teens.
  • While CELTA-holders are granted access to job boards through the program, other TEFL certifiers may offer more in-depth job placement services, especially with local schools.
  • Flexibility. CELTA courses require students to be on the school premises, whereas other TEFL programs can be available online.
  • CELTA requires that you already hold a high school diploma and be at least 18 years old. If you’re younger or don’t hold a high school diploma, a different TEFL program may be a better option.

CELTA is far from the only great TEFL program; other well-known TEFL-accrediting bodies include WTEFLAC, ACCET, and IATEFL. In addition, there are many TEFL programs that aren’t accredited by any of these institutions that fulfill the standards required by CELTA: well-trained teachers, at least six hours of practicum with real ESL students, and at least 100 hours of classroom work.

How do I choose between a TEFL or CELTA certification?

When I was choosing a TEFL program, I felt a bit lost: there are dozens of different programs on offer in Paris at several different price points. Because the CELTA popped up again and again on calls for teachers in Argentina -- and because I had flexibility in terms of time commitment and price point -- I didn't hesitate in choosing the CELTA.

Not only did I gain valuable knowledge about English as a language, but the CELTA teaching tools and practicum experience gave me a good deal of confidence in the classroom and set me up for professional success.

However, the CELTA name proved to be much less essential than I thought it would be. I didn't end up teaching in Argentina, but I did teach in France and in the U.S. The CELTA name certainly opened a few doors, but many of my colleagues had attended other training programs and were just as talented -- and hirable -- as I was.

At the end of the day, the CELTA is far from the only program that can give a prospective teacher confidence, experience, and skills. Do your homework and seek out a reputable TEFL program (with a practicum with actual ESL learners), and you’ll likely be getting a great education regardless of the name of the certification program you choose.
