Our Mission

Colorado International School (CoIS) is an independent school that provides the highest-quality international education in a language immersion environment to prepare its students for lifelong learning and future educational success.

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

Established in 2005, Colorado International School (CoIS) is the first and only accredited (AdvancED) international immersion school in Denver, Colorado and the Rocky Mountain Region. CoIS is a private, non-profit international school, an immersion school which serves students in preschool through 8th grades (ages 3-14).  CoIS immerses students in French, German, Mandarin, Spanish and English in our day programs. We also offer Enrichment Program courses in Persian (Farsi), Russian, Italian, Japanese, and Arabic as well as in our five main languages.

Colorado International School is authorized to implement the International Baccalaureate Primary Years Programme (IB PYP).  IB World Schools share a common philosophy—a commitment to high-quality, challenging, international education—that we believe is important for our students.

To our knowledge, Colorado International School is the only international immersion school in the Rocky Mountain Region with PYP authorization and with curricular immersion in the preschool years; and possibly the only school in the world with PYP authorization in English and in  four immersion languages: French, German, Mandarin, and Spanish.

October 2016: Colorado International School is delighted to announce that its Preschool Program has become the first preschool program in Denver to be accredited by AdvancED under its rigorous Early Learning Schools standards!
