Original Research by School Decision on Old Mill High
Old Mill High is a large comprehensive public high school in Millersville, an unincorporated suburban community in central Anne Arundel County. The school serves students in ninth through twelfth grade. Its student body is diverse, with Black, White, and Hispanic students each making up a substantial portion of enrollment, along with smaller shares of Asian students and students of two or more races. A substantial share of students qualify for free or reduced-price meals, reflecting a mix of economic backgrounds in the attendance zone. Data on students with individualized education plans and English learners was not available.
Millersville itself is known locally as a more affordable alternative to the nearby Severna Park area. Housing stock largely dates from the 1960s through the 1980s, and the community is primarily residential with a car-dependent layout. There is no traditional downtown. The Baltimore & Annapolis Trail, a rail-trail, runs through the historic core, and Kinder Farm Park provides recreation space. A new community park is under construction. Major employment is not centered in Millersville; many residents commute to Fort Meade, Baltimore, or Annapolis. Growth in the area appears stable, with no major new housing developments prominently reported.
Academically, state testing data presents a mixed picture. For the most recent year available, the school’s English language arts proficiency rate shows that a majority of students met proficiency standards. In contrast, math proficiency is markedly lower, with only a small fraction of students reaching that threshold. Algebra I results follow a similar pattern. Science proficiency data was reported for an earlier year and for a different grade level, so it does not align with the high school’s current grade span. A parent may want to ask the school directly about current science assessment performance. No graduation rate was provided in the data available, which is a notable gap for a high school; families should confirm this metric with the school or district.
The school is part of Anne Arundel County Public Schools, a large district that recently opened a new comprehensive high school, Severn Run High School, in the nearby Severn area. That opening has redrawn some attendance boundaries, which could affect which students attend Old Mill High. The district brief did not include other parent-relevant changes.
No information was available on the school’s program offerings, such as Advanced Placement courses, career and technical education pathways, or dual enrollment opportunities. Similarly, data on discipline, staffing ratios, chronic absenteeism, and course access was absent. Parents seeking details on these topics would need to consult the school’s website or contact the administration directly.
For a family considering this school, the picture is one of a large, diverse high school set in a stable suburban community. The academic strength is in English language arts, while math performance is a soft spot that warrants further inquiry. The missing graduation rate and program details mean that many of the factors families often weigh most heavily are not documented in the available data. The school’s size and demographic mix may appeal to families who value a broad cross-section of peers, while those seeking a smaller environment or a school with clearly documented outcomes may want to look more closely at the school’s own publications.
