# Key Findings from the 2013 NAEP State Mapping Analysis

## Key Findings

The following are the key findings regarding state proficiency standards as they are measured on the NAEP scale.

• In reading, the difference in NAEP equivalent scores between the states with the highest and lowest proficiency standards is about 76 points on the NAEP 0-500 scale. This difference is about twice the size of the standard deviation on the NAEP national grade 4 reading assessment (37 points) and more than twice the 30-point difference between Basic and Proficient performance levels for NAEP grade 4 reading.
• In mathematics, the range of NAEP equivalent scores from the state with the lowest to the state with the highest proficiency standards is 49 points on the NAEP 0-500 scale, about one and a half times the size of the standard deviation of the NAEP mathematics scores for public school students (30 points) and about one and a half times the 35-point difference between Basic and Proficient performance on NAEP set for grade 4.

• In reading, the difference in NAEP equivalent scores between the states with the highest and lowest proficiency standards is 83 points on the NAEP 0-500 scale. The difference is about twice the size of the standard deviation on the NAEP national grade 8 reading assessments (34 points) and about twice the 38-point difference between Basic and Proficient performance on NAEP set for grade 8.
• In mathematics, the 60-point distance separating the highest and lowest proficiency standards is about one and a half times the size of the standard deviation of the NAEP mathematics scores for public school students (36 points) and one and a half times the 37-point distance between NAEP Basic and Proficient performance set for grade 8 mathematics.

Although the wide variation in standards persists, the  number of states with grade 4 reading standards at or above the NAEP Basic level increased from 15 in 2009 and 20 in 2011 to 25 in 2013. Although in 2009 and 2011 no state standard was in the NAEP Proficient range, in 2013 two states had grade 4 reading standards in that range. In mathematics, the  number of states with grade 4 standards at or above the NAEP Basic level also increased, from 44 in 2009 to 46 in 2011 and 47 in 2013, with five states having standards in the Proficient range in 2013 compared with one state each in 2009 and 2011.

At grade 8, the number of states with reading standards at or above the NAEP Basic level increased from 35 in 2009 and 36 in 2011 to 41 in 2013 (with one state standard in the Proficient range in 2013 compared with none in the previous years). In mathematics, 41 out of 49 states included in the study had standards above the NAEP Basic level, and increase from 39 both in 2009 and 2011; three of these state standards were also above the Proficient level, compared with one state standard in 2009 and two in 2011.

## State Profiles

The 2013 State Mapping report is supplemented by a survey that was conducted to gain contextual information about the general characteristics of a state's assessment program, and to identify any changes in that program since 2011 that could affect the interpretation of the 2013 mapping results. Download your state's profile to see information about the methodology of this survey and results for your state.
