How to read these scores

What is NSCAS?
NSCAS is the statewide standardized test administered by Nebraska public schools.
What does "% On Track + 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 53.3% mean for English Language Arts at GARDEN COUNTY ELEMENTARY SCH?
It means about 53.3 percent of students tested at GARDEN COUNTY ELEMENTARY SCH performed at grade level or above on the NSCAS English Language Arts test in 2024-25. The statewide average for Nebraska that year was 57.6%. 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 Nebraska, 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?
Nebraska Department of Education, Nebraska Student-Centered Assessment System (NSCAS). School-level All Students subgroup from the NEP public data downloads (nepdata.education.ne.gov). Headline metric is the cumulative "On Track + Advanced" rate (top 2 of 3 NSCAS levels: Developing / On Track / Advanced).
How often is it updated?
NSCAS 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.
