How many times have you heard people like Bill Gates, Arne Duncan, Joel Klein (remember him?) and other so-called reformers say that poverty doesn’t matter, that poverty is an excuse for poor teaching?

I have always believed that poverty imposes tremendous burdens on students and their families: hunger, homelessness, lack of medical care, illness, etc.

The best evidence of the difference that poverty makes is SAT scores. The poorest kids have the lowest scores, the most affluent have the highest. The difference from bottom to top is nearly 400 points. To be exact, it is 398 points.

The Wall Street Journal suggests a new name for the SAT: the Student Affluence Test.

What does the SAT measure? Family income and family education.

Those with vast resources of their own probably think that poverty is a personal defect rather than the inevitable result of an inequitable tax system.
