Summary:

[Upper Rio Grande School District C-7](https://www.schooldigger.com/go/CO/district/03300/search.aspx) is home to exactly one high school, [Del Norte High Junior/Senior High School](https://www.schooldigger.com/go/CO/schools/0330000290/school.aspx), which serves grades 7 through 12 in Del Norte, CO, with a small student body of 173. The school has shown a remarkable upward trajectory in its state ranking, jumping from the bottom quarter of Colorado high schools (261st place, 1 star) in 2023-2024 to the upper half (145th place, 3 stars) in 2025-2026. With a student-teacher ratio of 11.8:1 and just over half the students qualifying for free/reduced lunch, this is a small, closely-knit academic environment.

Academically, [Del Norte High Junior/Senior High School](https://www.schooldigger.com/go/CO/schools/0330000290/school.aspx) presents a mixed but generally improving profile. Its graduation rate of 89.3% outpaces the state average of 85.6%. The school shines in reading and writing, particularly in 8th grade and the 9th/10th grade PSAT exams, where proficiency rates exceed state averages by 10 to 15 percentage points. However, math proficiency remains a concern, lagging behind state averages in 7th grade and PSAT 10, and sitting at just 50% proficiency in 8th grade, despite being 12 points above the state. College readiness shows a similar split: while underclassmen PSAT scores are strong, 11th-grade SAT reading/writing proficiency (50%) falls 10 points short of the state average.

The most significant red flag for the school is chronic absenteeism; 38.5% of students were chronically absent in 2024-2025, far exceeding both the district (27.0%) and state (28.4%) rates. Additionally, parents should be aware that with only 25-30 students per grade, proficiency percentages can swing dramatically from year to year based on a few students. While the rapid rise in state ranking is encouraging, sustained success will depend on addressing attendance issues and bolstering math and SAT readiness to ensure all students are fully prepared for life after high school.
