Summary

Union High School is a small public school in Nampa, Idaho, serving 213 students in grades 6 through 12 as part of the Nampa School District. Its size, grade span, and student profile make it more like an alternative or credit-recovery program than a traditional high school. In the 2025–26 SchoolDigger rankings, Union placed 100th out of 122 Idaho high schools (1 star), a sharp drop from the prior year when it ranked 47th. Historically, its rankings have been volatile, swinging from the top quarter of the state in 2007–08 to near the bottom in recent years—a pattern that reflects how much one strong or weak cohort can affect results at a school this small.

The most striking concern is chronic absenteeism. At 40.7%, Union's rate is nearly 5 times higher than nearby traditional Nampa high schools like Skyview High School (7.9%), Columbia High School (7.0%), and Nampa Senior High School (8.3%); only Initial Point High School matches it. Academic proficiency is also below district and state averages: ELA End of Course proficiency is 42.4% at Union versus 57.2% districtwide, and science proficiency is 27.7% versus 32.7% districtwide. The school reports no math test scores, which limits direct comparison with other schools. Graduation rates were very low in recent years, hovering around 38–54%, though the most recent reported figure of 82.5% appears to be a data artifact shared across all schools rather than a genuine improvement.

Union serves a higher-need student population, with 59.15% of students eligible for free/reduced-price lunch—well above the 35–42% range at nearby traditional high schools. The school also spends significantly more per student ($11,522) than Columbia ($8,147) or Skyview ($7,611) and has a much lower student-teacher ratio of 12.4. Despite these extra resources, outcomes remain low, a sign that smaller classes alone cannot overcome the barriers of chronic absenteeism and poverty. For parents, the key takeaway is that Union offers a small, individualized environment, but attendance is the biggest lever for improvement, with nearly 4 in 10 students missing school chronically.
