Although this will provide highest quality of academic curriculum, the remote only high school also has disadvantages. Being with peers in a physically colocated space is critical for kids to learn social skills that are equally important as academic skills. Being able to have a hybrid model of teachers or volunteers who can drive these interactions in small physical groups will provide the best experience.
Schools are more than just for a career. They are one of the foundation pillars on which our kids character and future are shaped. You can't teach empathy online. They learn when they see their friends breakdown in their arms after first breakup. They learn about bonding when they experience win or lose together arm in arm. As I said, online can teach everything intellectual but hardly anything emotional.
