Thank you for your input.
As long as kids are in a school program, I believe you are right about compelling them to attend public schools.
If they aren’t in a program, I believe they are required by law to attend to a certain age.
Perhaps that is no longer the law of the land. I’d like to think kids would have to be involved by law, in an education program until 16.
Doing a little digging around and it appears to be State laws and not Federal which govern compulsory education.

Every State makes it compulsory, though the ages at which it is compulsory vary from a high of ages 5 to 18 (Arkansas, Connecticut, DC, Hawaii, New Mexico, Oklahoma, and Virginia) to a low of ages 7 to 16 (Alaska, Idaho, Montana, N. Carolina, N. Dakota, Wyoming). Pennsylvania requires it from 8 to 17 years which is the same spread as 7-16.
