Beginning in 1990, a state component was added to NAEP. State assessments are administered in reading, mathematics, science, and writing for grades 4 and 8. The state assessments are the same as national NAEP and are administered at the same time in the same schools as the national assessments.
	Historically, 40 to 46 states and other jurisdictions have participated in state NAEP assessments. All states but one have participated in state NAEP assessments. View participation map. Reading and mathematics assessments are required every two years beginning in 2003. The new "No Child Left Behind" legislation requires states receiving Title I funds to participate in the biennial reading and mathematics assessments. Science and writing assessments are administered on four-year cycles with science administered in 2005 and writing in 2007. Writing will be administered at 8th grade only in 2005.
