Over the years, I've seen many teen homeschooling families turn to brick-and-mortar schools for high school learning. Sometimes it's because the teen craves increased peer interactions. Sometimes it's because the parents need to work outside the home or feel unprepared to mentor high school learning. Sometimes it's a combination of all three! Often, those families wish they could find the support they need without sacrificing the personalized learning piece of homeschooling.
If this sounds like you, the Princeton Learning Cooperative (PLC) could be the solution you seek. Check out this PLC Documentary created by PLC'er Konstantin von Schroder.
Full disclosure: I happily serve on PLC's Advisory Board.
