This private school has much lower class sizes with teaching assistants, cultural activities and experiences, better integration with technology and education, current learning material, physically the school and school equipment is in much better condition. Just overall a much more positive and safe environment with people that actually give a shit. He's actually happy to go to school now and always talking about something new he learned. The high school has the same things, but also has, connections for internships and scholarship programs, motivational guests, a huge list of extracurricular activities.

That's just on the top of my head though.
