Qualified disagreement here. I haven't seen a decent public school in our area, and there are certainly private schools that don't measure up to our standards, but with careful selection (given opportunities) often a good school can be found. My daughter's school is Christian, very conservative and academically rigorous, and she is thriving there. My son's school is tailored to his learning disabilities, and his teachers have skills (and patience) that I do not have. There are only 7 kids in his class this year - and the principal is a genius who believes in "her kids". My daughter would, I think, learn in the middle of the Gobi desert, but my son needs a little extra boost.
Of course they are also educated at home! Reading, study, research on the Internet, word games at the dinner table, nature study in the woods and stream behind the house, etc. etc. Both study aikido and ride horses, sing in the church choir, daughter is an altar server, etc. We certainly don't turn our children's education over to the schools exclusively! That is where many go wrong, I fear.
