How to read these scores
What is ND A+ (formerly NDSA)?
ND A+ (formerly NDSA) is the statewide standardized test administered by North Dakota public schools.
What does "% Proficient + Advanced" mean?
It is the share of students at the school who performed at grade level or above on the test, summed across the top two of four performance levels. A higher number is better.
What does 52.0% mean for Reading at CENTRAL CASS HIGH SCHOOL?
It means about 52.0 percent of students tested at CENTRAL CASS HIGH SCHOOL performed at grade level or above on the ND A+ (formerly NDSA) Reading test in 2024-25. The statewide average for North Dakota that year was 38.7%. The other students fell into the lower performance levels.
How is the state average calculated?
It is a weighted average, not a simple average of each school's number. We multiply each public school's score by how many of its students tested, add those together for all schools in North Dakota, and divide by the total students tested that year. This way a big school with 1,500 students counts more than a small school with 50 students, which is the right way to ask "how did the typical student do this year?". District and county averages on this page use the same method, just scoped to that district or county.
Where does this data come from?
North Dakota Department of Public Instruction, ND A+ (formerly NDSA) for grades 3-8 and 10. School-level All Students subgroup scraped from the Insights of North Dakota CsvHandler endpoint (chart-data feed). Headline metric is the cumulative "Proficient + Advanced" rate (top 2 of 4 levels: Novice / Approaching / Proficient / Advanced).
How often is it updated?
ND A+ (formerly NDSA) is administered once a year (spring). Results are released by the state in the summer or early fall. We refresh this page after each annual release.
