Summary

Union High School is a public high school in Nampa, Idaho, serving 171 students in grades 6-12. The school is part of the Nampa School District, which is ranked 80 out of 96 districts in the state and has a 1-star rating from SchoolDigger. Over the years, Union High School's statewide ranking has fluctuated, ranging from 47th out of 112 high schools in 2024-2025 to as low as 152nd out of 160 high schools in 2012-2013.

One of the school's key strengths is its impressive improvement in graduation rates, increasing from 38.5% in 2023-2024 to 82.3% in the most recent school year. This exceeds the graduation rates of nearby Columbia High School, Nampa Senior High School, and Skyview High School, all of which had an 82.3% graduation rate in 2023-2024. Additionally, Union High School outperforms the Nampa School District and the state average in science and English Language Arts proficiency.

However, the school faces some challenges, including a relatively high percentage of students receiving free or reduced-price lunch at 54.97%, which is higher than the nearby high schools. While Union High School has shown promising progress, it still lags behind some of the higher-performing schools in the area in overall academic performance and statewide rankings. Continued efforts to address these areas and support the school's diverse student population will be crucial for its long-term success.
