Who it serves
The measures behind the comparison
Bars: this school (the area around it for education). Black tick: average of Colorado middle schools.
Neighborhood family income (families with children near the school, NCES): 3.6× the poverty line. Enrollment (K–12): 760. Education is for adults aged 25–44 — the ages most likely to be parents — because the Census doesn’t publish parents’ education below the district level.

Each school’s CMAS scores are compared with what Colorado schools serving similar students score, using a model fit across all neighborhood schools. “Vs. expected” is in CMAS scale-score points; growth is CDE’s median growth percentile (50 is typical). Full method and caveats.
