Compared with similar schools

Colorado middle schools where 22–32% of students come from families below the poverty line (this school: 27%)

Similar schools nearby with higher scores

Family income strongly affects test scores, so comparing a school with others that serve families like its own is fairer than comparing it with the state average. The share of students below the poverty line is an estimate by the Urban Institute for 2022-23, made the same way in every state; it is a stricter measure than the low-income share above (free or reduced-price lunch, which goes up to 185% of the poverty line), so it is lower. “Typical” is the median: half of the similar schools score higher, half lower.

Students

Race and ethnicity, 2024-25

Students with disabilities: 17% of students (123) receive special education under an IEP (individualized education program), 2023-24; another 5% have only a Section 504 plan (support such as extra time or seating, without special education), 2023-24. Source: U.S. Department of Education, Civil Rights Data Collection.

Year-by-year history is loaded from the NCES Common Core of Data (2017-18 onward).
