At least in my locale, the necessity of a high school diploma has been easily overcome. Colleges know how to deal with this. I know at least a couple of families that have home-schooled their kids. One of those kids is now on a full ride scholarship at the state university, studying biochemistry.

Colleges are also full of students from public schools. America has plenty of good public schools (but also bad ones). America tend to be country of large differences and it shows in school results too.

Homeschooling parents love to use worst poorest least performing public school as a norm and best performing home schooled students as a norm.

Definitely true. And I have to disclose that my familiarity with homeschool kids is biased: They are all drawn from a particular demographic (educated parents) and from a particular activity (classical music), because my kids happen to participate in that activity as well.
