The Colorado International School (CoIS) parent community welcomes your support and involvement. As a group, parents work together to support both the school and teachers, help enrich the children’s education, build a community where current CoIS families and future CoIS families can grow. With the tremendous talent in our parent community, there are opportunities for everybody to get involved.

Families are encouraged to become involved in their child’s education as this involvement is essential to the child’s overall success. We welcome your participation!
