What Districts Get When They Switch to Mastery
Most states send test results back over the summer, after the school year has ended and the students have moved on to a new grade and a new teacher.
Seven districts decided they needed to know whether students were mastering content sooner.
This guide collects what happened after each of them moved to Mastery by Instructure for assessment: how closely the predictions matched real state scores, which accountability ratings moved, how quick results shaped tomorrow's instruction, and what changed for the teachers writing the tests.
Seven districts and one question: Did it work?
Here's who you'll meet and what stood out about each one.
District | State | Students | What stood out |
Hamilton County Schools | TN | 45,000 | Rose from a Level 1 to a Level 5 district and held it three years running |
Kershaw County School District | SC | 11,000 | A middle school jumped from "Average" to "Excellent" on the state report card in one year |
Lexington City Schools | NC | 3,000 | Seventh-grade math scores rose 25.7% in a single year |
De Soto School District 73 | MO | 3,700 | Double-digit annual growth on state assessments, now top of its region in core subjects |
Passaic County Technical Vocational Schools | NJ | 4,500 | Built one connected home for coursework and assessment data alongside Canvas |
Fairfield County School District | SC | 2,300 | Predictions land within three to five points of the state English exam |
Hortonville Area School District | WI | 4,200 | Shifted students from chasing points to owning what they understand |
The guide also walks through the research behind the results, including a 2025 multi-state validity study of more than 32,000 students in which Mastery predictions correctly identified who was on track 84% of the time
