Sample Design for the 2001 Assessment

			National Main Assessment Sample Design

For 2001, the National Assessment of Educational Progress (NAEP) sampling followed a multistage approach:

• sampling of geographic-based primary sampling units (PSUs),
   
  
• sampling of schools within PSUs, and
   
  
• sampling of students within schools.

Because NAEP state assessments are administered in even-numbered years, no state assessment was given in 2001.
