Believe it or not there are public school systems where kids can specialize in job related skills starting in the seventh grade. In this same system my daughter earned two years of college credit while in high school, and she was just typical in her program.
Though most public schools are designed as pure college prep, there are a growing number of vocational high schools. Vocational training doesn't necessarily imply blue-collar work the way it once did. Many vocational high schools offer college credit. In my area off the top of my head I can think of a high school for performing artists, a high school for law enforcement professionals, and a high school for health care professionals. They all offer college credits.
Yes. But there's nothing like that near us.
My kids don't even have wood shop or electronics in their schools. At least I got to do that.
