The NJ DOE sizes up our new NAEP scores:

Under the Christie Administration, New Jersey continued to improve its overall national ranking on the 2011 National Assessment of Educational Progress (NAEP), the largest nationally representative and continuing assessment of what America’s students know and can do in various subject areas. Between 2009 and 2011, New Jersey maintained its ranking as the 2nd highest performing state in the country in grade 4 and 8 reading, and improved from 5th to 4th in grade 4 math, and from 5th to 3rd in grade 8 math. Though nearly all subgroups have improved since 2003, the gap between low- and high-income students remains one of the largest in the country. In grade 8 reading, New Jersey ranks 50 out of 51 states plus DC in the size of its achievement gap.
