If you’re exploring a career in English language teaching, you’ll often see the terms TESOL and TEFL used interchangeably, but they’re not exactly the same.
Key Differences
- TEFL focuses on teaching English in non-English-speaking countries (e.g. Japan, Spain, Brazil)
- TESOL is broader and includes teaching both overseas and in English-speaking countries
- TESOL is often preferred for roles involving migrants, refugees, or international students
- TEFL is commonly used for entry-level teaching jobs abroad
- Both qualifications typically require at least 120 hours of study
What Do Employers Require?
- Around 80-90% of entry-level English teaching jobs worldwide require a TESOL/TEFL certificate (minimum 120 hours)
- Higher-paying roles and reputable institutions increasingly ask for more advanced qualifications
- Many employers now prioritise candidates with practical teaching experience
- A university degree is often required alongside a teaching certificate
The Gold Standard: CELTA
The CELTA (Certificate in English Language Teaching to Adults) is widely considered the gold standard in the industry.
- Accredited by Cambridge and recognised globally
- Includes real classroom teaching practice with feedback
- Highly regarded by top-tier language schools and institutions
- Often required (or strongly preferred) for competitive roles in Europe, the Middle East, and top schools in Asia
