Yup. Good teacher don't scale. My son is in a charter school the controversial Success Academy which do really well (top 3% in new york state) even with kids who are homeless and living in shelters. But this is because 1) Parents have to apply for the lottery and if they get in they have to be engaged 2) School is run almost like a Catholic school in how strict it is (but with a much more effective reward/punishment system) 3) Teachers aren't part of the union which means they can fire bad teachers. They are also fairly young. This is a very different school than the one I attended in Denmark where I grew up but I have to say it's working remarkedly well. My hope is that the school will provide my boys with an understanding of self-discipline and then I will take them to a more free-form school (like alt school) in the second part of their educational lives so that they can benefit from the freedom to explore and find their own perspectives using their basic skills (reading, writing, math & music) Have no idea if this will work but that's how I am going to do it.
