In some states/districts, partial homeschooling is an option for everyone. Students register as homeschoolers, and then take selected courses at school (usually up to some maximum percentage of the school day), with grades for those classes going onto their homeschool transcript. Under those circumstances, they don't sit for state exams. In other states/districts, students can register as partially enrolled, or with a modified day, in which case their homeschooled grades are reported back to the school for recording on the school transcript, and they usually do sit for state exams.
