I attended Nyack College in 1965-67, was a C&MA lay volunteer in Viet Nam in 1971-72, and am now on the board of directors of Inter-American School, a Christian school located in Quetzaltenango, Guatemala.
Again this year, Inter-American School is looking for volunteer Christian teachers for the 2015-16 school year. All teachers must have a bachelorís degree. Teaching certification is preferred, but not required. Spanish is helpful but not necessary. Volunteers receive a living stipend which adequately covers housing, food and basic living expenses.
IAS is a Christ centered school offering an English immersion curriculum based on U.S. college preparatory standards. All classes, pre-kinder through grade twelve, are taught in English. Most of our 200 students are Guatemalan, however about 15% come from Europe, Asia, and other nations in the Americas.
Here is a short video made on the IAS campus. http://vimeo.com/29278784
