Rsu 51/msad 51, ME - District Data

Original Research by School Decision on Rsu 51/msad 51

RSU 51, also known as MSAD 51, is a prekindergarten-through-grade-12 district serving the Cumberland and North Yarmouth area of southern Maine, in Cumberland County. The district operates four schools: Mabel I Wilson School for the earliest grades, Greely Middle School 4-5 for the upper elementary band, Greely Middle School for the middle grades, and Greely High School. The community sits in one of the more expensive housing markets in the state. Weighted home values across the district's zip codes run well above both the Maine and national benchmarks, with the Cumberland Foreside area carrying particularly high valuations. A family looking to buy here faces a price-to-income ratio that is elevated relative to the national figure, and estimated monthly mortgage costs reflect the current rate environment. Rent data was not available for this district. For families already settled in the area, the housing picture is less pressing. For those considering a move, the cost of entry is real.

Academically, the district's state assessment results are strong. In math, roughly four out of five tested students in grades three through eight reached proficiency or above. English language arts results were similarly high, with a comparable share of students clearing the proficiency bar. Science results, measured on a smaller tested group, landed lower but still showed a solid majority of students performing at proficient or above. These are well above typical Maine proficiency rates and reflect a district where the baseline academic expectation is high. No multi-year trend data was available, so it is not possible to say whether these results represent growth, stability, or decline from prior years. A parent wanting that longitudinal picture may want to look into this further with the district.

The student body is large for a Maine district of this type and is predominantly white. A small number of students identify as Hispanic, Asian, Black, American Indian or Alaska Native, or two or more races. The district did not report free-or-reduced-price lunch counts, individualized education program data, or English learner figures, so the socioeconomic and special-populations picture is incomplete here. Without those data points, a parent cannot gauge economic diversity or the level of specialized support services from the available information alone. This is a gap a family might ask about directly.

No civil rights data, course access data, staffing figures, attendance records, or discipline data were available for this district. Program offerings such as AP, dual-credit, or career pathways were not reported. The district brief search returned only basic directory information and found no recent referendums, budget votes, curriculum changes, or property tax shifts that would signal a lasting structural shift in how the district operates. That absence is worth noting plainly: it means there are no publicly flagged disruptions or major investments to account for, but it also means the narrative cannot speak to strategic direction or recent community debate.

What the available evidence does say is clear. This is a well-resourced district in an affluent corner of southern Maine, producing strong proficiency results across tested subjects, particularly in math and English language arts. The housing market is expensive relative to the state and nation, which shapes who can access the district. The schools are organized in a way that separates the lower and upper elementary years, which some families see as a benefit of smaller, more focused grade-band communities. Families weighing this district should ask the schools directly about program offerings at the high school level, support services for special populations, and any trend data the state summary did not capture. The academic foundation here is solid; the gaps are in what the data did not report rather than in what it showed.
