While Custer High School's performance has been inconsistent, with fluctuations in its statewide ranking over the years, the school's focus on maintaining a low student-teacher ratio and supporting students from lower-income backgrounds is commendable. However, the school may need to explore strategies to improve student outcomes in key subject areas, such as ACT English Language Arts, Mathematics, and Science, as well as state assessments in Reading and Science, to ensure all students are receiving a well-rounded and high-quality education.
