Summary

Gilpin County Undivided High School in Black Hawk, CO is a small combined middle/senior high school serving about 200 students in grades 6-12, and this tight-knit mountain school punches above its weight. The school is part of the Gilpin County School District No. Re-1, which ranks 21st out of 115 districts in Colorado, and the school recently jumped to 80th out of 338 high schools (76th percentile, 4 stars) after ranking 123rd the previous year. With a student–teacher ratio of just 11.7-to-1 — much lower than the 20-to-1 ratios at nearby Fairview High School, Boulder High School, and Ralston Valley Senior High School — Gilpin offers individualized attention that larger schools cannot match.

Gilpin County Undivided High School's graduation rate of 97.3% is nearly 12 points above the state average (85.6%) and on par with top regional schools like Boulder High School (97.7%), Fairview High School (97.6%), Golden High School (97.3%), and Evergreen High School (97.0%). That's notable because 38% of students qualify for free or reduced lunch — far higher than at Ralston Valley Senior High School (9.0%) or Fairview High School (14.5%). Academically, the school is strongest in reading and science: SAT reading/writing proficiency is 78% (state: 60%), and 11th-grade science proficiency has consistently run 15–17 points above the state average (42.1% vs. 24.8%). Math is the clear weak spot, with all-grade CMAS math proficiency of just 27.5% versus the state's 37.3%, though 9th-grade PSAT math beat the state (53% vs. 40%).

The biggest concern is chronic absenteeism: 42.2% of students miss substantial instructional time, far above the state rate of 28.4% and higher than nearby Evergreen High School (24.4%) or Clear Creek High School (35.9%). Yet Gilpin County Undivided High School still graduates nearly all of its students — a counterintuitive result that may reflect the school's small size and close-knit community. Like many small schools, test scores and rankings fluctuate year to year, and there are achievement gaps between student groups. Still, for families seeking a small, community-focused school with strong graduation outcomes and genuine strengths in reading and science, Gilpin County Undivided High School deserves a close look.

Sunday, October 29, 2017

I am a parent and have been for the past 15 years of the Gilpin County School here in Black Hawk. The progress that has been made in the past 7 years or so is absolutely incredible.

I am very pleased with almost every aspect of our school and look forward to watching my daughter grow and learn right here at Gilpin for the next 5 years. Close Quote
