Summary

Old Mill High in Millersville, MD, is a large public high school serving 1,832 students in grades 9-12 within the Anne Arundel County Public Schools district, where 56% of students come from low-income households.

Old Mill High presents a mixed academic picture. On the positive side, its English Language Arts (ELA) proficiency rate of 52.6% is competitive with the state average. However, the school faces a severe challenge in mathematics, with only 4.3% of students proficient—a staggering 48.3 percentage point gap between math and reading scores. This math proficiency rate is the second-lowest among its direct peer group, far below the district average of 29.3%. While nearby schools like Northeast High (7.4% math) and Meade High (4.6% math) show similar struggles, the contrast with Severna Park High—just 4.79 miles away, with 40.4% math proficiency and a 9.66% low-income rate—highlights the strong link between socioeconomic factors and academic outcomes. Old Mill also struggles with chronic absenteeism at 31.5%, the highest among its peer group and well above the district average of 19.9%, while its graduation rate has declined to 88.6%, now slightly below the district average.

Despite these challenges, Old Mill’s ELA performance shows effective literacy instruction that could serve as a foundation for improvement. Notably, the school spends $16,502 per student—more than top-performing Severna Park High ($15,963)—indicating that funding alone isn’t the issue. Instead, the data points to high chronic absenteeism and poverty rates as key drivers of the school’s struggles. For parents, Old Mill offers a strong ELA program but requires urgent attention to math instruction and attendance to reverse its declining trends.

They can't get substitutes very easily and administrators don't enforce the rules. Students are very disrespectful and many have severe behavior issues that are not dealt with properly. Close Quote

My daughter has attended Old Mill since middle school. She is currently a 10th grade IB student. I haven't been satisfied with the teachers at this school. It appears that most of their class time is spent handing out worksheets and do very little classroom teaching. The children are teaching themselves! I require much more for my child and the teachers have not done such a great job challenging my daughters learning. I recognize that teachers are not paid very well, and my hope is that we can create a better learning system for students as well as compensate teachers better, which will in turn increase their desire to teach.

We are a military family, my children have attended eight different schools so far. OMHS is the worst one ever. We will be moving early to get away from this school. It is not military-friendly at all. The school has no leadership and teachers are never held accountable. My children's education has suffered Close Quote
