Popular destinations: South Korea, Japan, China, Spain, Czech Republic, Thailand, Vietnam. Many positions include housing, flights, and competitive salaries. CELTA holders get premium placements.
Teach from anywhere via platforms or independently. Requires good internet, a quiet space, and digital literacy. AI tools like Edooqoo help online teachers create professional materials instantly.
Build a client base locally or online. Higher hourly rates than school positions. Requires entrepreneurial skills alongside teaching skills.
Work at established schools (British Council, International House, local language schools). Structured environment with curriculum support and professional development.
Technically some schools hire native speakers without TEFL, but it's becoming rare. A TEFL certificate shows you can actually TEACH, not just speak English. It also helps you be a better teacher — untrained teachers often struggle with grammar explanations, lesson planning, and classroom management.
Absolutely! Many excellent English teachers are non-native speakers. TEFL courses are open to anyone with strong English skills (typically B2+). Non-native speakers often have advantages: they've learned English themselves, they understand learner difficulties, and they can explain grammar from a learner's perspective.
If you plan to make teaching a career, yes. CELTA is recognized worldwide, includes intensive teaching practice, and opens doors to better-paying positions. If you're testing whether teaching is for you, start with a quality online TEFL and upgrade to CELTA later if you decide to continue.
