* Significantly different from 2005 when only one jurisdiction or the nation is being examined.
1 The District of Columbia did not participate in the 2005 science assessment due to an insufficient sample size.
2  Department of Defense Education Activity. Before 2005, DoDEA overseas and domestic schools were separate jurisdictions in NAEP. For this table, 2000 data were recalculated for comparability.
