Degree Requirements
A bachelor’s degree is the most common requirement because it’s needed for the work visa, not because of teaching ability. The degree can usually be in any subject.

- Preferred but flexible: Spain (Auxiliares), Latin America, some European positions
- Not required: Cambodia, some Latin American countries, many online platforms
TEFL/TESOL Certification
A 120-hour TEFL is increasingly standard. The CELTA carries more weight in Europe and the Middle East.

- Required by most employers: All of the above plus increasingly in Korea and Japan
- Highly valued: Spain (CELTA), Middle East (CELTA/Delta)

- Flexible: Thailand, Vietnam, Cambodia, Latin America, Europe (EU passport helps)
