TEFL stands for Teaching English as a Foreign Language. A TEFL certificate is a short practical qualification that trains you to teach English to people whose first language is something else, either in a classroom abroad or online. It is not a teaching degree, and it does not qualify you to teach in Irish schools.
What a TEFL certificate is, and what it is not
The term is used loosely. There is no single TEFL qualification and no single body that owns the name. Courses sold as TEFL, TESOL or TEYL vary in length, assessment and whether anyone regulates them. That is why employers and visa offices usually ask about hours and teaching practice rather than the brand on the certificate.
Two qualifications have a clearer paper trail. Cambridge's CELTA is 120 hours, regulated by Ofqual at Level 5 in the UK, and assessed through written assignments and observed teaching practice. Trinity's CertTESOL is also Level 5 on the Ofqual framework, with a minimum of 130 guided learning hours and at least six hours of supervised teaching with real learners. Both are covered in TEFL vs CELTA.
TEFL and teaching in Irish schools
If you want to work as a teacher in an Irish primary or post-primary school, the route is a recognised teacher education qualification followed by registration with the Teaching Council. A TEFL certificate does not replace that. What TEFL does cover is English language teaching to adult and young learners in private language schools, language centres, tutoring companies and online platforms, in Ireland and elsewhere.
What a typical course covers
- How people learn a language and how to plan a lesson that has a clear aim.
- Teaching grammar, vocabulary, pronunciation and the four skills (reading, writing, listening, speaking).
- Classroom management, giving instructions and correcting errors without discouraging learners.
- Adapting for beginners, teenagers, young learners or business students.
- Observed or supervised teaching practice, on better courses.
The practice element is what separates a serious course from an information pack. Ask if you will teach real learners, for how many hours, and if a tutor gives written feedback.
Who a TEFL certificate suits
TEFL attracts graduates taking a gap year, career changers and people wanting remote work. It also suits people who already speak English fluently and want a structured start, since the course teaches the grammar you use without thinking about it. Native-speaker status is not the legal test in most places: visa rules usually turn on nationality lists, degrees and sponsorship, and these differ sharply by country.
| Question | What to check |
|---|---|
| Will it be accepted for a work visa? | Rarely the certificate itself. Visas depend on your degree, nationality, a sponsoring employer and background checks. |
| Do I need a degree? | Not for most courses. Many destinations, including South Korea and Japan, effectively do. See the country guides. |
| How many hours? | 120 hours is the figure most often quoted by employers and recruiters. Always ask the specific employer. |
| Is there live teaching practice? | Ask before paying. It is the single most useful feature. |
Ask which body regulates or awards the course, find the course on that body's own register, and confirm in writing that your target employer accepts it. Logos on a sales page prove nothing. See how to choose a provider.
What the labels on certificates mean
Level numbers come from qualification frameworks. Trinity describes Level 5 on the Ofqual framework as comparable to the second year of an undergraduate degree, which tells you about the standard of the course, not about whether it earns a visa. The words regulated and accredited are not interchangeable: regulation means an awarding body sits inside a regulated framework, while accreditation depends entirely on who is doing the accrediting and what they checked.
- Hours tell you volume, not quality. A 120-hour course with no live teaching is a different product from a 120-hour course with assessed lessons.
- Awarding body tells you who issues the certificate. Search for the exact course title on that body's own register.
- Teaching practice tells you if you will be observed and given feedback with real learners.
- Employer acceptance is the real test. Ask the school or scheme you want to join what they accept, in writing.
In Ireland, QQI (Quality and Qualifications Ireland) has published award standards for English language teacher training, and providers that want to offer a QQI-validated programme must go through its approval process. QQI's older ACELS scheme for English language schools stopped taking new applications in 2015. If a provider says it is recognised or approved in Ireland, ask by whom and for which programme.
Finally, a TEFL certificate is a starting point. Most schools hire on interview, a demonstration lesson and references as much as on the certificate, so treat the course as training you will actually use, and read the first month tips before your first class.

Is TEFL the same as TESOL?
The names overlap and employers generally treat them alike. What matters is the hours, the assessment and whether the course includes teaching practice.
Can I teach in an Irish school with a TEFL certificate?
No. Irish schools require a recognised teacher education qualification and Teaching Council registration. TEFL is aimed at language schools, tutoring and online work.
Do I need a degree to start a TEFL course?
Usually not, but a degree is often needed later for work visas in places such as South Korea. Check the destination before you pay.
How long does a TEFL course take?
A 120-hour course is commonly done in a few weeks full-time or a few months part-time. Intensive in-person courses run for about four weeks.
