Teaching abroad is a catch phrase used in first world countries for temporary teaching assignments outside of the teacher's home country. Overview of different programs There are many different programs that exist to help people teach abroad. If a person knows that they want to teach abroad but they are not sure if they are able to make the transition, they can pick a teaching program that goes from a semester to a couple of years. There are also programs where one can switch positions with a teacher overseas. When picking a program make sure it is a credible program. Three often-used paths for American teachers are teaching at a Department of Defense school, teaching at an international school, or working independently at any school accepting foreign applicants. U.S. Department of Defense Teaching at a U.S. Department of Defense (DOD) school is much like teaching at a school within the United States.

Costs to participate as a volunteer vary depending on the organization, the country and the length of the program. International volunteer programs usually vary in length from 2 to 12 months. Volunteers most often teach English but other subjects can also be covered, such as computer skills, AIDS/HIV awareness, science, math, etc. Volunteer English teaching programs exist in almost all corners of the world. Some countries with prominent English teaching programs are Chile, Spain, France, and Georgia.
