For more than a decade, the National Center for Education Statistics has been mapping state standards to the National Assessment of Educational Progress (NAEP) in reading and mathematics in grades 4 and 8. This process of “state mapping” shows where each state’s standards lie on the NAEP scale.

NCES has released the latest version of the state mapping report. Here are answers to three commonly asked questions about the report.

Why is NAEP used as the basis for comparison of state proficiency standards?

How are the states compared?

Here is an example of how “mapping” works (see the figure below). In state A, 71 percent of students scored at or above the Proficiency cut point on its state assessment in a given subject and grade. If we look at the NAEP scale, we find that 71 percent of students in state A scored at or above 243 on NAEP in the same subject and grade. So, we say that 243 is the NAEP scale equivalent score for state A in the given subject and grade. The same process is done for state B, in which 71 percent of its students also scored at or above Proficient on its state exam. Seventy one percent of students in state B scored at or above 252 on NAEP, making this the NAEP equivalent score.

## COMMENTS

I must be slow, as I had to read the how mapping works explanation more than once to wrap my head around it. Please correct me if I am wrong, but this is what I understand. In state A, 71% of students scored as proficient on the state assessment. To find the NAEP equivalent score, NAEP takes the top 71% from the NAEP assessment, and the lowest score is the NAEP equivalent mapping score for state A.
