Teachers are good, but the classroom sizes are too big. Your child can easily get lost in such big classroom sizes. If I am paying for a Catholic private education, I want to make sure I am getting my monies worth and unfortunately it wasn't so at St. Dennis. They also have the reputation as the East side "cheap" private school option and not a Catholic private school. If you want a real Catholic school education, look elsewhere, their are many other great options at the same price.
Some incredible teachers. Some teachers who encourage those kids who are already encouraged and discourage those kids who need the most help and create a peer hierarchy within the classroom. A great school and community if you have a round peg kid but if yours is a unuque square pegged kid, they will have a hard time fitting in with the other kids and teachers. Also, any parent should be prepared to volunteer generously. Leadership within the school is malapropos and there is a very small town gossipy culture at times. But it is a very safe and homey culture.
This year St. Dennis started a 4K program. My daughter loves it. The teachers are great. 4K is a half-day program. If you are interested register now for the 2010 - 2011 school year. At the last home and school meeting it was announced that there were only 4 spots left.
