Vocational Highschools seem to be the exception around here.
The high school I went to, graduated in 2015, was a vocational high school. Essentially, 50% of the time you were at school you were in a shop class, instead of just 45min a day.
In 9th grade you pick what shop you wanted to be in. They had a bunch of choices. Welding +fabrication, machine shop, electrical occupations, plumbing, cabinet making, masonry, a civil engineering class,multiple computer and communications based stuff, emergency services training (kids graduated with EMS certs), culinary classes, auto, diesel, small engine, even cosmetology, and dental hygiene.
A lot of the students graduate with multiple certifications that would cost 100s or 1000s of dollars to obtain on their own, and are completely ready to start working full time in their chosen trade. Most even have a job in their trade before they graduated. I was working 60 hours a week doing electrical work when I started 12th grade.
They did a six day shop and six day academic rotation. So you had six full days of only shop class. Then, you had six full days of only academic classes. Academic classes were split into four 1 1/2 hr classes, science, math, English, and social studies.
Frankly, I think that most high schools would be better off with this formula. Even if a student is bound to be academic genius, there is no downside to learning a skilled trade.
