World Teach arranges for volunteers to teach for one year in Ecuador, Costa Rica, Namibia, the Marshall Islands, or China. There is also a summer teaching program for each of these locations. Undergraduates may apply for the summer program, but the year-long program is intended for graduating seniors and recent college graduates.
No teaching experience is required, and program specifics vary at each location.
Travel is not covered, but most programs provide housing and a living allowance.
Deadlines vary depending on the country. Visit the website for more information.
