Mayor Michael Bloomberg's administration has pointed to improvements in previous state test results as a sign that its school reforms are working.
However, the most recent national math test for fourth and eighth graders indicate progress for students in city schools appears to have stalled since 2007, after showing gains in previous years.
The National Assessment of Educational Progress (NAEP) is known as the nation's report card and the one true check on state test results. Unlike the state test, which every student takes, only a sample of students takes the NAEP, so while raw scores for city students went up slightly this year, the bumps were so small, they are not considered statistically significant.
The national test found that only 35 percent of city fourth graders and 26 percent of eighth graders are considered proficient in math. In comparison, state test results that show 84.9 percent of city fourth graders and 71.3 percent of eighth graders are proficient.
