Original Research by School Decision on Cozy Lake Elementary School
Cozy Lake Elementary School in Oak Ridge serves children in prekindergarten and kindergarten only. This is a school for the earliest years of formal education, and everything about its profile is shaped by that fact.
The school enrolls roughly the number you would expect for a two-grade early elementary building in a mid-sized suburban district. The student body is predominantly white, with a substantial Hispanic minority and small numbers of Asian, Black, and multiracial students. About one in seven students qualifies for free or reduced-price lunch, which at the prekindergarten and kindergarten level is a rough proxy for household income among families with young children. The school is a regular public school within the Jefferson Township Public School District, situated in the portion of Oak Ridge that lies in Morris County.
State testing data is not available for Cozy Lake. New Jersey’s standardized assessments begin in grade 3, so the youngest students in this building are not tested. A parent looking for academic performance measures from the school itself will not find them here; the school’s purpose is early childhood and kindergarten readiness, not the kind of subject-area proficiency that later grades measure. The same logic explains the absence of a graduation rate, chronic absenteeism data, and civil rights outcome metrics. Those indicators simply do not apply to a prekindergarten through kindergarten building.
What the data does show is that the Jefferson Township district recently undertook a significant grade reconfiguration, effective with the 2025-2026 school year. Cozy Lake Elementary was not part of that change. The reconfiguration created a new Jefferson Township Intermediate School for grades 4 through 8, shifted Arthur Stanlick Elementary to grades 1 through 3, and placed White Rock Elementary at preschool through grade 3. That means Cozy Lake is one of two early-grade entry points in the district. Families whose children start at Cozy Lake will move to a different school for first grade, then again for fourth grade, and again for high school. The district’s family handbook lays out these feeder patterns.
Oak Ridge itself is a dispersed lake community that straddles two townships and two school districts, though Cozy Lake sits in the Jefferson Township side. The area is car-dependent and low-density, with no concentrated downtown. Route 23 is the main commercial corridor. The housing market in the broader Oak Ridge zip code shows a median home value near the upper end of what is typical for New Jersey, and the county housing market is active with a limited supply of homes relative to demand. The community is primarily residential, with lakes and wooded terrain defining the landscape.
Cozy Lake Elementary does not report data on special education identification rates or English learner identification rates, so it is not possible to say from available sources how many students receive those supports. The school appears to be a straightforward early childhood center within a district that has recently reorganized its elementary and middle school structure. For a family considering this school, the main considerations are the grade band it serves, the feeder patterns that follow, and the reality that this is a building for the very start of a child’s education, not a place where test scores or graduation outcomes are measured.
