Summary

Oakland Mills High in Columbia, MD, serves 1,413 students in grades 9-12 and is part of the highly-regarded Howard County Public Schools district, though it faces unique challenges compared to its nearby peers.

While the school has improved from a 1-star to a 2-star rating, its most pressing issue is a persistent crisis in mathematics, with only 7.8% of students proficient in math—dramatically lower than the district average of 42.1% and far below top-performing neighbors like River Hill High (49.4%) and Centennial High (34%). This math proficiency rate has remained below 8% for four consecutive years, indicating a systemic problem. On a brighter note, Oakland Mills performs relatively well in English Language Arts, with 61.9% of students proficient—above the state average of 51.7% and competitive with nearby schools like Long Reach High (62.8%). The school also struggles with chronic absenteeism at 31.3%, nearly double the district average of 17.4%, and serves a student body where over 43% are economically disadvantaged—a stark contrast to River Hill's 7.66%.

Despite spending $20,779 per student—higher than top-performing schools like River Hill ($17,496) and Centennial ($17,982)—outcomes remain low, suggesting funds may need to be redirected toward more effective interventions. The graduation rate has fluctuated, reaching 84.9% in 2024-2025, below the district average of 91.3%, while the dropout rate of 8.1% is nearly double the district's 4.9%. The contrast with River Hill, just 4.8 miles away, is striking: a 5-star school with 49.4% math proficiency versus Oakland Mills' 2-star rating and 7.8% math proficiency. This highlights how dramatically school performance can vary within the same district, driven largely by socioeconomic factors and the challenges that come with them.

This school is amazing. The ratings are so low because the majority of Howard County has a racial bias towards Oakland Mills. This place is absolutely amazing and the best memories I’ve ever created have been in this building. Close Quote

We just enrolled my daughter for her freshman year at Oakland Mills and we were greeted with the nicest staff members. We have always done private school and were a bit nervous to try a public school. They were so friendly and helpful and they were very patient with my daughter who had a ton of questions for them. I love this neiborhood and the people here are great! Close Quote
