logoHello, Hola, Bonjour, Guten Tag, and Ni Hao

Established in 2005, Colorado International School (CoIS) is a private non-profit international school.  An American-International immersion school which serves students in pre-kindergarten through 8th grades (ages 3-14).  CoIS immerses students in Spanish, Mandarin, German, French, and English in our day programs.
