The best time to apply for TEFL jobs depends on a few factors:
- Where you want to teach
- What kind of TEFL job you want.
Different countries have different hiring peak times, mostly because the academic years differ from country to country. For TEFL jobs like these, you would apply a few months before the start date.
For example, if you want to teach in a school in Thailand, the academic year starts in May. This means there are likely to be job openings advertised in November (for teachers leaving at the end of the year), and the few months before May.
However, many language schools allow you to start teaching any time of the year, so applications are open throughout the year.
