What is TESOL?
TESOL stands for Teaching English to Speakers of Other Languages. It is one of the most widely recognized credentials for teaching English online and abroad. While the terms TESOL, TEFL, and ESL are often used interchangeably, there are subtle differences worth understanding:
- TESOL (Teaching English to Speakers of Other Languages) — The preferred term in the United States, Canada, and Australia. It covers both teaching English abroad (EFL contexts) and teaching immigrants within English-speaking countries (ESL contexts). Most employers treat TESOL and TEFL certifications as equivalent.
- TEFL (Teaching English as a Foreign Language) — More commonly used in the UK and Europe. Refers specifically to teaching English in countries where English is not the primary language.
- CELTA (Certificate in English Language Teaching to Adults) — A prestigious, specific certification awarded by Cambridge Assessment English. It is a type of TESOL/TEFL certificate, but one that carries particular weight with higher-end language schools, universities, and British Council-affiliated institutions.
- ESL (English as a Second Language) — Refers to the field of teaching English, not a specific certification. When someone says they teach ESL, they mean they teach English to non-native speakers.
Which Certification Should You Get?
For online teaching, a standard 120-hour TESOL or TEFL certificate is the minimum requirement for the vast majority of employers. Here is how to decide:
| Certification | Hours | Typical Cost | Best For |
|---|---|---|---|
| TESOL (Online) | 120+ hours | $200–$500 | Most online teaching positions |
| TEFL (Online) | 120+ hours | $200–$500 | Equivalent to TESOL for most employers |
| CELTA | 120+ hours | $1,500–$2,500 | Premium schools, universities, career advancement |
| MA in TESOL | 1-2 years | $10,000–$30,000 | Academic positions, curriculum development |
