Summary:

The city of Union, Missouri is home to a single high school, Union High School, which serves students in grades 9-12. This school is part of the Union R-XI school district and has demonstrated solid academic performance, ranking in the top 26% of Missouri high schools for the 2023-2024 school year.

Union High School boasts a 4-star rating from SchoolDigger and has seen its statewide ranking improve from 138 out of 367 schools in 2024-2025 to 98 out of 378 schools in 2023-2024. The school's proficiency rates on the Missouri Assessment Program (MAP) tests are generally on par with or slightly below the state and district averages, with standout performance in English II and Algebra II.

Despite the economic challenges faced by its student population, Union High School appears to be well-resourced, spending $10,182 per student and maintaining a student-teacher ratio of 15.5, both of which are slightly better than the state averages. This suggests the school is able to provide its students with a quality education and the necessary support to succeed academically.
