Summary

Mount Hebron High in Ellicott City, MD, is a large, high-performing public high school serving 1,455 students in grades 9-12 as part of the highly-rated Howard County Public Schools district. The school stands out for its exceptional English Language Arts (ELA) performance, with 80.7% of students proficient—nearly 25 percentage points above the district average and 29 points above the state average. This places Mount Hebron among the top ELA performers in the area, comparable to other elite schools like Centennial High (84.2%) and Marriotts Ridge High (89.5%).

However, the school faces a significant challenge in mathematics, creating a stark 51-percentage-point gap between its ELA and math proficiency rates. Overall math proficiency sits at just 29.7%, well below the district average of 42.1%. This issue is largely driven by an "Algebra I bottleneck": only 16.4% of students taking the Algebra I end-of-course exam were proficient, dramatically lower than the district average of 41.2% and even below the state average of 21.3%. Interestingly, the school performs above average in higher-level math like Algebra II (37.7% proficiency), suggesting a two-tiered system where struggling students in foundational math contrast with high achievers in advanced courses. This pattern is unique among nearby top-performing Howard County schools, including Howard High and Centennial High.

Mount Hebron boasts a strong graduation rate of 93.7%, yet nearly 70% of students are not proficient in math, raising questions about college and career readiness. Chronic absenteeism is a growing concern at 20.9%, which is 3.5 percentage points higher than the district average and has remained persistently high for three years. The school spends $18,995 per student and has a student-teacher ratio of 15.6:1, indicating that challenges are not due to lack of funding. In contrast, schools just across the county line in Baltimore County Public Schools, such as Woodlawn High and Randallstown High, face even steeper hurdles with math proficiency below 10% and chronic absenteeism above 30%, highlighting the profound impact of district resources on student outcomes.
