I live in a HCOL suburb with a *fantastic* school system (and magnet schools in the area for high school if your child is particularly gifted/smart). Saw on FB that a friend of a friend is looking for a private school for their child to start Kindergarten next year. They are willing to pay $20k + per year for an "Ivy-league" quality education for the munchkin.
Those who suggested the excellent public schools were told "that's not an option" with no reason given.
Apparently there was a study in Australia - I've seen it referred to, but not properly cited - that said that small children who had bedtime stories with interaction (ie pointing to words in the book, talking about the book, etc) had an advantage over small children who didn't, even by age 15, and that this advantage is actually
greater than that of private vs public school.
We have a few public schools here with a great reputation, indeed one high school, McKinnon, is so well-thought of that over the years they've had to expand from 500 to 2,000 students, and house prices within its zone are $100-$150k more than just outside it, I mean literally across the street.
But then I think of what teachers tell me, "the number one determinant of children's academic success is parental involvement." Now I would think that if parents are willing to pay $20k pa, or go to the trouble of moving houses and spending an extra $100-150k for a house in a particular school's zone, then those are going to be very,
very involved parents.
And if you have a whole class of kids like that, they'll tend to encourage each-other. So my thinking is, it's less the teachers and more the parents and fellow students.
And a friend pointed out, "rather than spending $15k on a school, send them to a public school and spend $5k on tutoring when needed, same outcome."
So... read with your kids, be involved in their education, make sure they're at a place where their classmates have the same kind of parents, and if all else fails, get them some tutoring.
That's what we're doing, anyway.
