Summary:

The Hartford Union High School School District in Wisconsin is home to a single high school, Hartford High, which serves grades 9-12. The district and its lone high school have demonstrated strong academic performance, ranking in the top 25% of Wisconsin high schools and maintaining a 4-star rating from SchoolDigger for the past two school years.

Hartford High boasts a graduation rate of 91.0% for the 2023-2024 school year, exceeding the state average. The school's proficiency rates on state assessments, such as the Forward Exam and ACT, also surpass the statewide averages in several subject areas, including English Language Arts (58.46%), Mathematics (55.38%), and Science (53.23%) for the 2024-2025 school year. While the school's chronic absenteeism rate of 17.7% is a concern, its relatively low percentage of free/reduced lunch recipients (24.27%) suggests a relatively affluent student population, which may contribute to the school's strong academic performance.

The Hartford Union High School School District as a whole is also a strong-performing district, ranking 81 out of 426 in Wisconsin and maintaining a 4-star rating. This indicates that the district, and by extension Hartford High, are providing a quality education to their students and are among the top-performing schools in the state.
