S – NAEP reporting standards not met. N.A. – Data not available.
A 95 percent confidence interval for each estimate can be found at
8th grade science achievement levels.
Note: The District of Columbia, Puerto Rico and the U.S. Virgin Islands are
not included in maps and rankings because they are not states and therefore comparisons on many
indicators of child well being are not meaningful.
