We would consider it. My mother was a public school teacher. I have seen the impossibility of change there and honestly have no desire to support the schools or teacher's unions. They are not set up to produce excellence.
I would consider sending my child to a catholic school, like the one I grew up in. However, most catholic schools these days are not like my elementary school. They lack discipline and are basically public school proxies.
Most non-parochial schools would be out of our price range.
Thus home schooling is the only option left.
