These are the technical notes for "Mapping State Proficiency Standards onto the NAEP Scales: Results From the 2017 NAEP Reading and Mathematics Assessments." The National Center for Education Statistics (NCES) has periodically published reports using results from the National Assessment of Educational Progress (NAEP) to compare the proficiency standards states set for their students. Since standards vary across states, the results of the various state assessments cannot be used to directly compare students' progress. However, by placing a state standard onto the NAEP scale, a common metric for all states, a NAEP equivalent score of that standard is produced, which can be compared across states. The 2017 edition of this report highlights the results of mapping state proficiency standards onto the NAEP scales using state assessment results from the 2016-17 school year and the 2017 NAEP assessments for public schools. The study focuses on the reading and mathematics standards that states set for grades 4 and 8. For each state, the report displays the NAEP equivalent scores with a range of 0 to 500.
