DS turns 3 in June and will start Pre-K in September. SO and I already know we want to enroll him into a private school, but I have questions. Is there a difference between Private vs. Catholic vs. Montessori schools? I'm doing research, and we want to base our decision based on curriculum and the tuition. I don't where to begin, but we have to register soon. Should I hold off on private school until kindergarten and do a Head-Start? Or should I go ahead and enroll him in private pre-school so he can start kindergarten with the same kids?
