​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Mapping State Proficiency Standards

Since 2003, the National Center for Education Statistics (NCES) has compared each state's standard for proficient performance in reading and mathematics by placing the state standards onto a common scale defined by NAEP scores. This process of "state mapping" shows where each state's standards lie on the NAEP scale, providing important contributions to analysis. Learn more...
Illustration of State Mapping. If State A reports that 70 percent of its students in the NAEP sample of schools meet the state's standard for Proficient and if 70 percent of the students in the NAEP samples score higher than 241 on the NAEP scale, then 241 is the NAEP scale equivalent for that state’s standard.
