Choosing a TEFL course is harder than comparing logos. In this market, “accredited,” “internationally recognized” and “approved” can describe different things: a private quality-review scheme, a regulated qualification, an awarding organisation, or a provider’s own marketing. None of those words alone proves that every Thai school or authority will accept a certificate.
The practical test is to verify the exact course and award, inspect how you will learn and practise teaching, and ask the employers you may apply to what they accept. A TEFL certificate is evidence of training. It is not, by itself, a Thai teacher licence or permit, immigration permission, or work permit.
If you are still deciding whether training is necessary at all, start with Do You Need a TEFL Certificate to Teach in Thailand?. This guide picks up at the next question: which course is worth your time and money?
What does “TEFL accreditation” mean?
There is no single worldwide public TEFL accreditor whose stamp automatically settles acceptance in every country, school or hiring process. Different private organisations offer course or provider accreditation; national regulators oversee particular qualifications within defined jurisdictions; and employers decide what they accept for a job.
Ask what the claim refers to:
- Provider accreditation: an organisation says it has assessed a training provider against its own published standards.
- Qualification regulation: a regulator oversees a named awarding organisation and particular qualifications within its jurisdiction. This is not blanket approval of every course sold by a provider.
- Awarding organisation: the body that awards or certifies the stated qualification. Its identity should appear clearly in the terms and certificate information.
- Validation or endorsement: an organisation may approve a programme under a partnership or endorsement arrangement. Check exactly what it has agreed to cover.
- Employer recognition: a particular school, recruiter or authority says it accepts a certificate for a particular purpose. This is the decision that matters for your target role.
These labels are not interchangeable. For example, Ofqual explains that it regulates qualifications and awarding organisations under its remit, not training providers as such. Its register can help you verify an exact qualification; it cannot tell you whether a specific Thai school will hire you. Ask for the qualification title and number, then check the official Register of Regulated Qualifications.
A private accreditor’s active directory and standards can also be useful evidence. Read the standards, who performs the review, what is assessed, how often approval is renewed, and whether the exact provider and course appear in the current register. A badge image or a claim that a course is “internationally accredited” is not enough to answer those questions.
Is there one official TEFL accreditation for Thailand?
The official Thai sources relevant to teaching permissions describe teacher licensing or temporary permission, immigration and work-permit processes. They do not establish one universal TEFL-course accreditation that every employer must accept.
That distinction matters. A course may be accredited by a private body, or lead to a qualification regulated in another country, without that fact automatically satisfying a Thai school’s hiring criteria or an authority’s requirements. Conversely, an employer may value practical training and an identifiable award without requiring a particular private accreditor’s logo.
When a course claims to be “approved by the Thai Ministry of Education,” ask what exactly is approved: the school, a course, the premises, a certificate, or a separate activity. Ask for the issuing authority, document or registration details, scope, validity dates and the exact certificate awarded. Do not infer that course approval grants you permission to teach or work.
What Thai employers may accept
Acceptance depends on the employer, job, applicant and current rules. Before you pay a non-refundable deposit, ask the type of school or recruiter you are targeting:
- Do you require a TEFL/TESOL/CELTA certificate for this role?
- Is there a minimum training-hour requirement, and how do you count it?
- Do you require assessed teaching practice with real learners? How many hours?
- Do you accept this exact course title and awarding organisation? Can you confirm in writing?
- Are there separate degree, nationality, English-proficiency, experience or document requirements?
- Who handles the applicable teacher-permission, visa and work-permit process, and what does the employer need from me?
A recruiter’s general reassurance is not a guarantee of hiring, teacher permission, visa approval or work authorization. Keep the response and course terms in writing, and reconfirm if your target employer or circumstances change.
A TEFL certificate is not a Thai teaching permit, visa or work permit
A TEFL course teaches skills and may award a training certificate. It does not itself confer the right to teach or work in Thailand.
For school teaching, Khurusapha (the Teachers’ Council of Thailand) handles professional licences and relevant temporary permissions. Government information describes temporary permission as case-specific and requested by the school; check current KSP guidance and the employer’s route for your situation. The KSP licence and temporary-permit lookup lets users check licence or permit identifiers.
Immigration permission and permission to work are separate processes. The Ministry of Foreign Affairs publishes Non-Immigrant B information for work, and the Department of Employment publishes teacher/instructor work-permit forms and requirements. The school or employer should explain which documents and sequence apply to the role. See our practical Thailand teacher visa and work-permit guide for the related process.
Do not rely on course advertising that says a certificate “qualifies you to work legally” without naming which legal permission it means. Ask the school and relevant authority about your exact case.
Is a 120-hour TEFL certificate enough?
“120 hours” is a useful starting point for comparing course scope, but it is not a universal legal threshold established by the Thai sources cited here. It also does not tell you how much trainer contact, assessment or supervised practice is included.
Compare the hour breakdown. Are the hours tutor-led contact, guided learning, independent study, assignments, or a mixture? Is the figure defined consistently? Can the provider show a syllabus, assessment method and sample timetable?
A named qualification such as Cambridge English CELTA specifies more than a headline hour count. Cambridge says CELTA includes at least 120 hours of tutor contact, assessed assignments and six hours of assessed teaching practice per candidate, along with supervised planning and feedback. Use that as an example of detail to look for, not proof that every 120-hour TEFL course is equivalent.
Why teaching practice and feedback matter
Practice can help you turn lesson plans into classroom decisions, but the word “practicum” covers different experiences. Ask:
- Will I teach real English learners or practise only with classmates?
- How many minutes or hours will I teach myself?
- Will a qualified trainer observe each lesson?
- Will I receive specific written or verbal feedback and have a chance to improve?
- Is teaching practice included in the published course fee and guaranteed for every trainee?
- What happens if a school visit or placement is cancelled?
Observed practice does not guarantee a job, and more hours are not automatically better if they are not supervised or assessed. Evaluate the design, feedback and support around the practice.
TEFL course checklist before you book
Use this checklist to compare options side by side.
Identity and claims
- Get the full legal name and location of the course provider.
- Get the exact certificate or qualification title, awarding organisation and any qualification number.
- Ask who “accredits” or “approves” the course and what that body reviews.
- Check the named body’s current standards and official directory yourself.
- If a qualification is described as regulated, verify the exact award on the regulator’s register. Confirm the provider’s role separately.
- Ask a target employer whether it accepts that exact certificate for the role you want.
Training and assessment
- Request the syllabus and a breakdown of contact, guided-learning and independent-study hours.
- Check the trainer qualifications and how much individual tutor support is included.
- Review the assignments, assessment criteria, resubmission rules and certificate conditions.
- Confirm who teaches you, who assesses your work and who signs the award.
- For in-person training, ask about observed teaching practice, real learners, feedback and cancellations.
Costs and terms
- Get the total price, deposit, remaining balance, taxes, materials and any extra charges in writing.
- Read cancellation, refund, deferral and replacement-course terms before paying.
- Confirm course dates, attendance requirements, completion deadlines and certificate delivery.
- Treat placement, interviews, salary and visa assistance as separate services with written eligibility conditions.
- Make sure the certificate wording and provider’s legal identity will be verifiable after the course.
Red flags to investigate
A red flag is a reason to ask for evidence, not always proof of fraud. Pause before paying if a provider:
- promises universal recognition, guaranteed employment, a teacher licence, visa or work permit with no conditions;
- displays an accreditation badge but will not name the accreditor or link to its active listing and standards;
- uses “government approved” without identifying the authority, scope, document and validity;
- advertises a regulated qualification but will not provide the exact title or registration number;
- counts every hour as supervised teaching when the timetable shows mostly self-study;
- cannot explain whether observed practice is with real learners, individually supervised and included in the fee;
- pressures you to pay immediately, hides refund conditions or changes the fee after a deposit;
- provides no named trainer, syllabus, assessment policy or way to verify a certificate.
A careful provider should be willing to answer specific questions in writing. If the answers stay vague, compare another course.
A worked example: what to verify on a provider page
Essential TEFL’s current site describes a 120-hour in-person course in Bangkok, observed teaching practice and a “TQUK approved” certificate. Its syllabus page describes a separate 168-hour TQUK Level 5 route. These are provider statements, not an independent audit by SiamTEFL.
Before relying on those claims, ask Essential TEFL for the precise certificate wording, the identity and role of the awarding organisation, what “approved” means for the 120-hour award, and the exact teaching-practice and assessment schedule for your intake. Verify any regulated qualification using its exact title and official register entry. Then ask your target employer what it accepts. Our independent Essential TEFL review compares the provider’s published options and terms; it does not replace those checks.
The short answer
Choose a TEFL course by checking the exact award, evidence behind any accreditation claim, useful supervised practice, transparent assessment and written employer acceptance. A 120-hour label or accreditation badge alone cannot tell you whether a course is suitable or accepted for your plans in Thailand.
Start with the target job and work backward: ask employers what they accept, verify the provider and award, read the full terms, and confirm the separate teacher-permission, immigration and work-permit path with the employer and relevant authorities.
