Only those who can and that is few as a percentage. Education reforms addressing public school failure should be a top issue right up there with immigration and the economy and crime. I'm flabbergasted minimized this failure is, but union money is sufficient to quell criticism apparently.
The number of homeschoolers is about 6%. Private schools about 9 and another in charter schools or magnets is another 6%. That’s just over 20% of students in ho chose something other than their local public schools. There are 20 states looking into some type of school choice.
As more kids leave public schools, the public schools will get worse because the more involved parents with the better behaved kids will take the options. Unless the government goes full totalitarian, which is entirely possible, the schools will collapse. Add the number of teachers quitting, colleges closing education programs due to low enrollment, and it will get worse, causing more parents to bail.
