I wonder about this general approach of talking about years ahead or behind in a lot of these reports and articles...
I could never quite pin it down but I assume the real data was maybe 4 standard deviations higher on the same standardized tests.
The article which you linked makes its "SEDA data sets" available to peruse if you choose to identify yourself and agree to their terms of use.
Since it seems really unlikely you could take an entire school district and just advance everyone up some number of grades.
Agreed. However the article linked in the OP did not suggest that. Neither did the article which you linked... it merely provided a comparison of averaged scores in various school districts, and correlated this to median family income. This is interesting, and I started a new thread for it:
NYT interactive: Money and academic success.
Did you have thoughts on the research and article in the OP?
