From Peace Corps Wiki
This page is a work in progress, but will eventually include information about staging and training. Briefly, Staging is a 2 day orientation with your group in one of the major US cities that the Peace Corps has a regional office in. Training is the 2-3 months of training you will receive in your assigned Peace Corps country, and it consists of language, culture, technical, health, safety, and more.
Check back with us soon for more information.
