Welcome to the Global Headquarters Homepage

ACSI is privileged to be a part of God's robust worldwide movement in Christian schooling. The Global Department is focused on serving two different international elements.

"National" Christian schools are those located outside of the U.S. and primarily focus on serving the indigenous population, following the curriculum guidelines of that particular country. ACSI has 20 country or regional offices around the world providing services to these national Christian schools movements. Our aim is to help provide culturally relevant effective Christian education, led by local educators, in an economically sustainable in their own context.

"International" Christian schools are those located outside of the U.S. serving the expatriate community and often times, a portion of the host country population. Frequently, instruction is in English with a Western-style curriculum. The ACSI International School office within ACSI headquarters in Colorado Springs, CO serves international schools located in more than 75 countries.

Serving together,
