Unfortunately, I haven&#x27;t kept up on my data for about 15 years, but back then two of the most strongly correlated factors of a student&#x27;s performance were 1) how many books were in their home, and 2) how many college educated adults lived nearby.  The amount spent per student had a tiny positive correlation. That said, I&#x27;m sure there&#x27;s a minimum baseline of spending per student that needs to be achieved.<p>With all the raise to the top and gates foundation money floating around since then, I&#x27;m sure there is better data now. But, those factors really stuck with me.
