It was in my school. You took a 90 day class where you learned basic home economics, planning, cooking, etc.
Home Economics would be more popular if it was renamed something like "Keys To Independent Living". I enjoyed the class, back in the day. My hubby did, too. You learned a lot of good lessons, before college, living independently, marriage, etc. Unfortunately, by the time our brood attended high school, it was no longer a course option.
It should be available to all high school students that want to learn it.
Why be mandatory? Forcing people to learn something never works.
