TEFL is a broad category of English-language teaching qualifications, while CELTA is a specific Cambridge qualification with standardised course requirements and assessed teaching practice. Choose CELTA when employers specifically request it; choose another TEFL/TESOL course only after checking that it meets your target market's expectations.
CELTA is one named qualification inside the wider ELT training market
Cambridge describes CELTA as a qualification for teaching English as a foreign language and states that the course includes hands-on teaching practice and observation. By contrast, 'TEFL' can describe many different courses from different providers, so quality and assessment vary.
Use employer demand to decide
Search current job adverts in the countries or language schools you want. If they specifically ask for CELTA, Trinity CertTESOL or an equivalent observed-practice qualification, a short online TEFL certificate may not satisfy the requirement. If they ask only for 100- or 120-hour TEFL/TESOL, a different course may be suitable.

CELTA
A specific Cambridge English teaching qualification with a defined syllabus, authorised centres and assessed practical teaching.
Generic TEFL
Can range from introductory online certificates to rigorous programmes with substantial assessment. The acronym alone does not indicate quality.
Evidence to check
- Employer wording
- Observed teaching practice
- Total training hours
- Awarding or quality-assurance arrangements
Where LCT UK programmes fit
LCT TEFL/TESOL programmes can support different levels of professional preparation. Compare them against the jobs you want rather than presenting them as automatically equivalent to CELTA.
Assuming all 120-hour TEFL courses are the same as CELTA because the total learning time seems similar.
Practical next steps
- Collect 10 to 20 job adverts from your target market.
- Note which qualifications are named.
- Compare practical teaching and assessment requirements.
- Choose the credential that matches employer expectations.
Bottom line
Choose CELTA when its standardised practical training or employer recognition is important. Choose another TEFL/TESOL programme when its curriculum, assessment and acceptance fit your specific goal.
