OCS is a private, independent school for missionary families located in the southern Mexico, Oaxaca. OCS uses a curriculum based on a Christian worldview, but true to the academic standards expected of schools in the United States of America. It is considered a college preparatory school, but accommodates those students who do not plan on attending university.
The primary purpose of the school is to support the educational needs of English-speaking missionary families in and around Oaxaca, Mexico who want their children to be educated in English and prepared for university in the United States. Thus, the majority of students come from English-speaking missionary families who live in the Oaxaca area.
