Colegio Decroly Americano (CDA) was established in 1993 as a private, bilingual (Spanish-English), co-educational, non-sectarian school, and is run by a Board of Directors. The school is authorized by the Guatemalan Ministry of Education and offers a U.S.-Guatemala program.  

In its first year CDA provided schooling for approximately 225 students in grades 1-4. The school now instructs students from Infants to 12th Grade and has kept a steady enrollment above 1000 students. The grades are divided into four divisions: Early Learning Center (Infants-Kindergarten), Elementary (Grades 1-5), Middle School (6-8), and High School (9-12).  

The school has grown immensely since its first years. During the last three years the school has added new classrooms, laboratories, a synthetic soccer field, a weight room, bathrooms, and a state-of-the-art multi-purpose gymnasium.

Since 2008 CDA is internationally accredited by the New England Association of Schools and Colleges (NEASC) and it is an active member of a number of school associations including the Association of American Schools of Central America (AASCA), the Association of American Schools of Mexico, Central America and the Caribbean (Tri-Association) and the Association for the Advancement of International Education (AAIE).
