My daughter goes to this school, and she's in pre-k and she loves this school and so does she. Since she started attending ICS, she is even smarter and more knowledgeable and it makes me a proud mother. The children's learning has no end. If you are contemplating about sending your child here, please do and you as well as your child will be so happy. This school makes learning fun!!!

I have two students currently at ICS. One is in first grade and the other in third, and this is our fourth year as part of the ICS family. I''ve been very pleased with this school on all fronts; the academics are first class, family support is outstanding, and perhaps most importantly, they believe in high standards in a loving, diverse and supportive environment. The kids are happy and engaged every day, and complain when I pick them up that they do not want to leave. There is low teacher turnover, and the administration is accessible and very in touch with each student as an individual, never a "number". I can't recommend this school enough, and am proud to be an ICS mom.
