– Not available. Massachusetts, Montana, Nevada, and North Dakota were not included in the study due to data not being available. States that did not have a general end-of-grade reading/English language arts or general mathematics assessment in grade 8 that all students were required to take were not included in the analysis.
† Not applicable.
1Although Louisiana and Ohio administered the PARCC assessment, they were not included in the estimation of the NAEP scale equivalent of the PARCC proficiency standard because both states used PARCC’s Approaching Expectations level as their standard for proficient.
2Wisconsin administered the SBAC assessment but was not included in the estimation of the NAEP scale equivalent of the SBAC standard for grade 8 reading because of issues related to test administration.
NOTE: The numbers reported in this table are rounded. Relative error is a measure of how well the mapping procedure reproduces the percentages reported by the state as meeting the standard in each NAEP-participating school.
