Someone quoted 15k USD spent in Baltimore for each student. That is a lot of money to attract top talent.
Inner city school systems are great at grinding up passionate personnel, making them quit or just surrender to do things that look good on paper but don't improve anything.
I don't know the answers, but I do know this -- it's a hell of a lot less than what gets spent in the NY metro area.
According to the US Census[1], out of the largest 100 US Public School systems Baltimore ranked near the very top in spending per child (5th out of 100). Baltimore spent $15,793 per child. Only New York and Boston spent considerably more.
