What this means: About 49% of students here test proficient in math and reading, compared with the roughly 50% typical for Missouri schools with a similar share of low-income students. BeatsExpectations measures results against demographically similar schools rather than by raw scores, and this school falls within the typical range, neither among Missouri's top nor bottom 10%.
BeatsExpectations runs a per-state regression of proficiency on free/reduced-lunch share, then scores each school by residual. How this is calculated →

How to read these scores
What is MO DVT (Growth)?
MO DVT (Growth) is the statewide standardized test administered by Missouri public schools.
What does "Growth Percentile vs MO Peer Schools" 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 89.3% mean for English Language Arts at NIANGUA HIGH?
It means about 89.3 percent of students tested at NIANGUA HIGH performed at grade level or above on the MO DVT (Growth) English Language Arts test in 2024-25. The statewide average for Missouri that year was 49.5%. 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 Missouri, 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?
Missouri Department of Elementary and Secondary Education / SAS EVAAS, Missouri Data Visualization Tool (MO DVT). Per-school value-added growth percentile from the public MO DVT API at modese.sas.com. NOTE: This is a GROWTH metric, not a proficiency metric. A "Growth Percentile" of 80 means this school grew faster than 80% of Missouri peer schools on the MAP Grade-Level Assessment over the year — NOT that 80% of students were proficient. School-level MAP proficiency is gated behind the MCDS portal login and is not currently ingested.
How often is it updated?
MO DVT (Growth) 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.
