I am also an ICA parent and am not the least bit religious. Just want to straighten out a few "facts."
1. School day is 6 1/2 hours, not 5.
2. Small World already had a new principal for the 2012/13 academic year. ICA also had a new principal after spring break. The two schools have not shared a principal since the opening of ICA in August 2012.
3. The school does not devote one hour each day to religious study. There is a morning assembly on Mondays and an afternoon assembly on Fridays. Certainly, religion will be brought up during the assemblies, but other themes will be introduced as well (reading during literature week, why smoking is bad for you, etc.) Prayers are said in the morning, before meals, and at the end of the day. Bible stories are read in class from time to time; Christian-themed artwork is done sometimes - but by no means are they part of the daily routine.
We just had our parent/teacher conference last week, and the end-of-year reports issued. Seeing how my child grows in ICA is an amazement. She had some issues, but the teacher is on top of things and very helpful. It's very difficult for a teacher to act "kind" for one whole year and not be noticed by the parents and the children! and my child and all her classmates just love their teacher. I send and pick up my child twice a week, and I went to all the field trips. The overall atmosphere at ICA is supportive and caring. The parent community is warm and friendly.
I like the fact that there isn't much homework, but the children are still learning. My child is an average student, but comparing to ESF's same year, her reading level is ahead by at least 6 months, math on par, and writing a bit below. However, as I mentioned before, she had some issues, so the fact that she could come this far during the last year is a miracle by itself.
ICA is a great school if you are looking for smaller class size, caring teachers, and emphasis on moral values. I wouldn't say there aren't any drawbacks. As a new school, resources and hardware cannot compare with more established schools. What I am most impressed about the management is how they spend their money. I saw the way they set up the school, and unlike some schools, they really tried to do everything on a shoestring budget so the money could actually be spent on the children. There is no fancy office or recruiting a large office staff count.
Hope this helps other parents when making a decision!
