Funding is obviously a bullshit metric because per-student spending adjusted PPP in many developing countries's private school systems is a fraction of that in the US and those students start farther behind and end farther in front.

Why should an arbitrary child whose parents are paying 100,000 INR in India end up with better start to finish improvement over an arbitrary child in the US whose government is spending $17,000? Here are the numbers adjusted to match:

100,000 INR converts to $1,202

India's PPP coefficient is 3.5x

Therefore, 100,000 INR is equivalent to $4,200 in the US.

A quarter of the spending and the start-to-finish delta is much higher there. The reason we can't do that here is multifaceted, but maybe the answer is looking to how their schools do it.

it is almost never the schools and teachers. It is the culture and parents.
