I help tutor homeschool kids in science. They have to have curriculum, because in many states they have to document it. It’s part of the state overlook and regs making sure all those homeschoolers are “accountable”, doncha know.
Many of the more experienced families want to fly without curriculum, but that’s not totally possible because of the state.
Government: messing up its own and then coming in and wrecking what you’ve got right.
I have my own curriculum for the courses I teach. I’ve taught chem, bio, physics, math, history and english. I tailor it for each student, depending on their requirements.
It’s not ‘government approved’. It is, however, effective...
If homeschoolers needed documentation, I’d be happy to provide it, but it’s not quite the same. ;)
