Greencastle-Antrim Middle School is a regular public middle school serving grades 6-8 in the heart of Greencastle, a small historic borough in southern Franklin County surrounded by rapidly growing Antrim Township. The school sits on the eastern edge of the borough, on a shared campus with the high school and a newly opened administrative and alternative-education building that opened in the 2024-25 school year.
The school enrolls a student body that is predominantly white, with about two-fifths of students qualifying for free or reduced-price lunch. The enrollment is stable across the three grades. State testing data shows that English language arts proficiency is stronger than math proficiency. On state assessments, the school posted proficiency rates in the middle ranges: students testing at proficiency or above in ELA reached nearly three-fifths, while math proficiency was lower at about two-fifths. In science, tested students (a smaller subset of the overall enrollment) performed more strongly, with proficiency above two-thirds. The school's overall proficiency index places it in the top quartile relative to other districts in Franklin County, suggesting it outperforms the county median on the subjects and grades that are tested.
The Greencastle area is one of the fastest-developing zones along the Interstate 81 corridor in central Pennsylvania. Surrounding Antrim Township, which has grown substantially in recent years, has active plans for several major housing developments and is seeing new apartment complexes, subdivisions, and significant warehouse and distribution employment take root along the interstate. The borough itself maintains a walkable historic downtown with small shops and Victorian-era buildings, though residents note that downtown retail keeps limited hours. The town has several civic anchors, including a public library, playground, and access to a large community park system in the township with trails, sports facilities, and natural play areas along a creek. Housing values in the Greencastle zip code are below the state benchmark, and the area is increasingly attracting young families drawn to the school district's reputation.
The district has faced a structural budget challenge in recent years. Publicly reported, the district has made near-annual property tax increases to manage gaps between revenues and spending, driven partly by substantial charter school tuition costs and per-pupil state funding that runs well below both regional and state averages. A parent evaluating the school may want to look into the district's current financial trajectory and any planned tax impacts. On the positive side, the district completed a major facilities upgrade in the form of the new ACE Building, which opened in August 2024 and consolidated scattered administrative functions, returned classrooms to the elementary and middle schools, and brought school board meetings back onto campus after being held offsite for several years. For families in the Greencastle area considering this middle school, the combination of modest academic performance on state measures, a community in active growth, and an aging-to-aging-but-improving district facilities picture will shape the experience.
