While test scores at public schools across the country remained stagnant, the San Diego Unified School District (SDUSD) made some gains in reading and mathematics last year, according to the Nation's Report Card.
Test scores among SDUSD's fourth-grade students showed the most improvement from 2015 to 2017 -- a six-point jump -- when compared to other large urban school districts across the country, according to results released Tuesday on the National Assessment of Educational Progress (NAEP).
SDUSD students at the eighth-grade level also showed an increase in scores from 2015 to 2017, though the change was only two points higher than the national public school average, the assessment showed.
The results of the latest Nation's Report Card weren't great.
Fourth-graders nationally made no improvements in math or reading, while eighth-graders' scores were flat in math and only slightly improved in reading, according to NAEP.
Overall, only roughly a third of American eighth-graders are proficient in reading and math along with about 40 percent of fourth-graders.
The figures are in line with recent trends. Students made big gains in the 1990s and early 2000s, but there have been no major improvements since then.
The results show that racial disparities persist. African-American students were out-performed by their white peers at both grade levels.
"There is still much work to be done to close achievement gaps and ensure that our young people are ready for success in college, careers and life," said Carissa Miller, executive director of the Council of Chief State School Officers. "It is clear we as a country must do better by all of our students, especially our lowest-performing kids."
In eighth grade, the average reading score was 267 out of 500, 1 point higher than in 2015, but 7 points higher than when the reading test was first administered in 1992. For math, the average score was 283, similar to two years before.
Peggy Carr, Associate Commissioner at the National Center for Education Statistics, said the increase for eighth-grade reading was due to improvement among higher-performing students. Lower-performing students had similar results in 2017 as in 2015.
The picture was different for fourth-graders. Low-performing students did worse in math and reading, while higher-performing students stayed at the same level.
The results were the first since the test was changed from paper to computer-based.
States that saw improvements in eighth-grade reading included California, Florida, Georgia, Indiana and Washington. Meanwhile, Alaska, Arizona, Delaware, Louisiana, among others, saw lower results for fourth-grade math.
