NCLB math tests are harder, study says

A study being released today says the math tests being used by states as part of NCLB are harder than the reading tests. And The Associated Press story makes this interesting correlation:

The findings come a little more than a week after the federal government reported students have been making much more progress in math than in reading in recent years.
Michael Petrilli, the think tank’s vice president for policy, said it makes sense that students’ math skills are improving if there are high expectations of them in that subject.
“If the bar is higher, you’ve got to work a lot harder,” he said.

The study also found that California is among the states with the hardest tests in both reading and math.
