Learning Curve: A troubling score gap

Maureen Downey:

In a new report contrasting proficiency scores on state exams to federal tests, Georgia comes across as a very easy grader.
“States are setting the bar too low,” said U.S. Education Secretary Arne Duncan in response to the release Thursday of the study “Mapping State Proficiency Standards onto NAEP Scales: 2005-2007.”
The federal study compares proficiency standards of states using the results of the National Assessment of Education Progress — often called the Nation’s Report Card — as the common yardstick.
A national test given to select students in every state, NAEP is the only nationally representative and continuing assessment of what America’s students know and can do in various subject areas.
Because students across the nation take the same NAEP assessment, state-to-state comparisons can be made.
