|The relationship of SES to standardized achievement test scores has been well-know since the Coleman Report in 1966. |
Desegregation as a means for reducing the relationship to zero has also been tried--to no avail.
The authors sniff a more productive line of reasoning when they speculate that maybe the differences are in the "curriculum." Of course, "it's the instruction." But we get no more than the sniff. The instruction the students received remains a black box. Until we get inside the box, which cannot be done by computer analysis of data that happen to be available, we'll not advance beyond confirming that there are SES differences that are positively related to standardized test scores.
