I agree, in the right district you can get a great education. However, there is a difference in behavior in the classrooms. In public school, kids are frequently distracted by kids that don't have the discipline that you will see in a Chaminade classroom. If there is a behavior problem, it is easily handled, whereas in public school, it can escalate and disrupt learning over a long period of time.

The alumni connections are also a huge plus. That said, I have one son that chose public school and one chose private. Both have great academics at their fingertips. Different kids thrive in different environments.
