How to read these scores
What is CMAS?
Colorado public-school students in grades 3 through 8 take the Colorado Measures of Academic Success (CMAS) in English Language Arts and Math each spring. Science CMAS is administered at grades 5, 8, and 11.
What does "% Met or Exceeded Expectations" mean?
It is the percentage of students at the school who scored at "Met Expectations" or "Exceeded Expectations" on the CMAS 5-level performance scale (Did Not Yet Meet, Partially Met, Approached, Met, Exceeded). Met and above is Colorado's grade-level benchmark. A higher number is better.
How should I read a single score?
Each percent represents the share of tested students who performed at grade level or above. Compare the school number against the state, district, and county averages on this page to see whether it is above or below typical.
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 Colorado, 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?
Colorado Department of Education (CDE), Colorado Measures of Academic Success (CMAS). School-level overall results published annually by CDE. Headline metric is the cumulative "Met or Exceeded Expectations" rate (top 2 of CMAS's 5-level performance scale).
How often is it updated?
CMAS 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.
