TEFL & TESOL Certification - Ultimate Guide to Teaching English Abroad & Online

TEFL & TESOL Certification

Your Passport to Teaching English Abroad, Online, and Worldwide

1. What is TEFL / TESOL?

TEFL (Teaching English as a Foreign Language) and TESOL (Teaching English to Speakers of Other Languages) are foundational professional credentials that certify educators to teach English to non-native speakers. Whether you plan to teach online, work in international schools, or live abroad, a accredited TEFL or TESOL certificate is the standard requirement for job placement and work visa issuance.

TEFL vs. TESOL: TEFL focuses on teaching English in countries where English is not the primary language (e.g., Germany, Japan, Brazil). TESOL encompasses teaching non-native speakers both in English-speaking countries and abroad.
Industry Standard (120 Hours): Employers and visa offices universally require a minimum of 120 hours of coursework from an accredited provider.
No Prior Degree in Education Needed: Open to native and non-native English speakers with strong language proficiency (CEFR C1–C2 level).
