TEFL stands for Teaching English as a Foreign Language. Simply put, this is usually used to talk about teaching English to people who live in a non-English speaking country and who want to learn English for business or to take an exam, etc.
It is pretty much equivalent to TESOL and TESL.

Qualifications & Pay
The usual requirements are a degree with a TEFL Certificate such as the ICAL TEFL Certificate. The better jobs also usually ask for experience as well whilst other jobs will take experience over a degree.
Salaries are sometimes paid in both the local currency (the Peso) and USD. A good local salary will be about $500 USD (€396, £318) per month which is enough to live on well. Sometimes an accommodation allowance will be added to this.
