Percent of North Carolina 8th grade students who performed at or above the NAEP Proficient level in Math

Last updated: 2019

(not available for all indicators)



The share of North Carolina 8th graders scoring “at or above proficient” on the National Assessment of Educational Progress (NAEP) Mathematics Assessment. NAEP Proficient means students have demonstrated “competency over challenging subject matter.”


Nearly 37% of North Carolina’s 8th grade students scored at or above proficient on the NAEP 8th grade math assessment, placing our state 20th among all states in 2019. In Virginia, the top-performing southern state, 38% of students scored at or above proficient in math. Nationally, Massachusetts had the highest share of 8th grade students earning proficient scores on the NAEP math exam (47%).

By 2030, the goal is that 42% of North Carolina’s 8th grade students will demonstrate math proficiency on the NAEP assessment. This goal was set by the myFutureNC Commission; while this is a seemingly small numeric increase, it represents a potentially significant improvement in state performance on this indicator.


Math learned in elementary school and middle school provides a foundation for high school math, which is critical for future attainment and success in the labor market. Success in 8th grade math is a key milestone which indicates whether students are prepared for high school math classes. Research has shown that students who complete more and higher levels of math classes are more likely to graduate from high school and college and have higher earnings in life.

The entry for NAEP in the Encyclopedia of Quality of Life and Well-Being Research notes: “NAEP is often referred to as the Nation’s Report Card, a common ‘yardstick’ that provides data on how states, districts, and various student groups perform against common achievement standards and compare to each other in terms of these standards.”

Data from NAEP provide a common measure of student achievement across the nation and are used to inform educational policy and practice.


Meeting the 2030 Goal

North Carolina needs another 5% of 8th graders to score at or above proficiency on the NAEP math assessment to meet the statewide NAEP 8th grade math goal.

In 2019, 37% of NC 8th graders scored at or above proficient on the NAEP mathematics assessment.

By geography

Bar chart showing percentage of NC 8th graders earning "Proficient" or higher on NAEP math exam, 2019, by geographic area, sex, demographic group, economic status, and overall NC state average.Note: NAEP geographic definitions are based on the National Center for Education Statistics local classifications detailed here.

Students from North Carolina’s suburban school districts were the most likely to score at or above proficient on the NAEP 8th grade math exam (43%) followed by students from city districts (38%). Rural students had the third highest scores (35%). Students from towns were least likely to score at or above proficient in math (24%).

By sex

Female students were more likely to score at or above proficient on the NAEP 8th grade math assessment than male students: 38% versus 35%.

By race/ethnicity

Asian (70%) students were the most likely to score at or above proficient on the NAEP 8th grade math assessment followed by white students (47%). These were the only two student groups to exceed the statewide goal. Multiracial (38%), Hispanic (26%), black (19%), and American Indian (16%) students fell below the statewide goal for proficiency on the NAEP 8th grade math exam.

By economic disadvantage

Students who are economically disadvantaged—meaning they received of free or reduced price lunch—were less likely to score at or above proficient than not economically disadvantaged students. Nearly half of not economically disadvantaged students scored at or above proficient on the NAEP 8th grade math exam (49%), more than double the share of economically disadvantaged students (20%).


Where does the data for NAEP 8th Grade Mathematics come from? 

Eighth grade math assessment scores for all states were obtained from the NAEP Data Explorer .

How was the data calculated? 

This number is a direct download from NAEP. It is the number of 8th grade students scoring at or above NAEP proficient in Mathematics divided by the total number of 8th grade students assessed.

Information about the NAEP Mathematics Scale Scores and Math Achievement Levels for Eighth Grade  are available online.

Who is included? 

NAEP is a sample survey that is designed to be representative of all schools nationally and all public schools at the state level. More information on the sample is available here.

Who isn’t included? 

NAEP data does not include home school students. State data does not include private school students. Among public school students, some students with disabilities and some English Language Learners may not have been able to participate.

FAQ 

How often are NAEP assessments given? 

NAEP assessments are conducted every two years.

Is the NAEP Proficient level equivalent to being “on grade level?” 

No. NAEP proficiency means students have demonstrated “competency over challenging subject matter” and are set much higher than grade level. Achieving NAEP proficiency is not the same as being “on grade level,” which refers to how students perform on local curriculum and standards.” This means that students who test at the NAEP ‘Basic’ level might still be actually reading at a 4th grade level.
