Summary

Great Mills High in Great Mills, MD, is a large public high school serving 1,697 students in grades 9-12 as part of the St. Mary's County Public Schools district, with 57.45% of students qualifying for free or reduced lunch in the 2024-2025 school year.

Great Mills High presents a mixed picture for parents. On the positive side, the school shows a notable strength in English Language Arts, with 55.4% proficiency in 2025-2026, above the state average of 51.7%. Additionally, students taking Algebra II perform exceptionally well, with 79.4% proficient, far exceeding state averages. However, the school faces significant challenges. The graduation rate is critically low at 83.0% for 2024-2025, the lowest among nearby schools like Chopticon High (90.0%) and Patuxent High (93.5%). Chronic absenteeism is alarmingly high at 39.7%, nearly double the district average of 27.3% and far exceeding rates at Leonardtown High (24.7%). Math proficiency overall is a major concern, with only 17.5% of students proficient, roughly half the district average of 36% and the lowest among all four compared schools.

Despite spending $17,379 per student—more than higher-performing Leonardtown High ($15,689)—the school struggles to translate resources into outcomes, likely due to the high level of economic disadvantage. The school does have a strong subgroup of Military Connected Students, ranking in the 40th percentile statewide, which could be a foundation for broader improvement. For parents, this means Great Mills High offers pockets of excellence, particularly in English and advanced math, but requires targeted support to address attendance, graduation, and foundational math skills for the majority of students.
