The American School Foundation, A.C. (ASF), located in Mexico City, serves students from Kindergarten through 12th grade in four schools: the Early Childhood Center (ages 4-7), the Lower School (grades 1-5), the Middle School (grades 6-8), and the Upper School (grades 9-12). The American School Foundation, A.C. has two primary languages of instruction, English and Spanish. The degree to which each language is reflected in our program varies from level to level. It is our goal that all students become completely bilingual.

ASF is an American school with an international flavor attributable to its diverse enrollment. By nationalities, the student body of 2,400 is approximately 60% Mexican, 26% from the United States, and 14% from nearly 30 other countries. Its 17-acre campus and facilities, as well as its academic and extracurricular programs, are similar to or exceed those in the United States.

The Southern Association of Colleges has accredited the ASF education program. Through special agreements, ASF studies in the Middle and Upper Schools are revalidated by the Mexican Ministry of Public Education (SEP) and the National Autonomous University of Mexico (UNAM). ASF is an International Baccalaureate (IB) World School and as such is authorized by the International Baccalaureate Programme headquartered in Geneva, Switzerland, to provide the Primary Years, Middle Years, and Diploma curriculum. In addition, the School is a member of the Association of American Schools of Mexico (ASOMEX), the Tri-Area Association, and the National Association of Independent Schools, headquartered in Washington D.C. Active in a variety of professional organizations the ASF faculty is involved in many activities sponsored by those entities.
