Original Research by School Decision on Stonybrook Elementary School
Stonybrook Elementary School serves third through fifth grade in Kinnelon, a low-density, affluent suburban borough in Morris County about thirty-three miles west of New York City. The school is one of four in the Kinnelon School District, sitting between Kiel Elementary (Pre-K through second grade) and Pearl R. Miller Middle School. The borough itself is overwhelmingly residential, with limited commercial activity centered on a single shopping plaza along Route 23. Many residents commute to employment elsewhere, and the community is defined by wooded lots, private lake communities, and county parkland rather than a walkable downtown.
Stonybrook is a regular public school with a student body that is predominantly white, with Hispanic students making up the next largest group, followed by Asian students and students of two or more races. A very small share of students qualify for free or reduced-price lunch, reflecting the borough's high median household income. The school serves only grades three through five, so there is no graduation rate to report, and the school does not serve grades that take high school-level assessments.
On state assessments, Stonybrook's students perform at a level that places the school in the top quartile among districts in Morris County for overall proficiency across tested subjects and grades. In math, the share of students scoring proficient or above was strong in third grade, dipped somewhat in fourth grade, and was very strong in fifth grade. In English language arts, proficiency was solid across all three grades, with the highest share in fifth grade. In science, which is tested only in fifth grade, a majority of students scored proficient or above, though the rate was lower than in math and ELA. A parent may want to ask the school about the fourth-grade math dip and the science results to understand what supports are in place.
The school's student body is small for a grade-three-through-five configuration. The share of students who qualify for free or reduced-price lunch is very low, consistent with the borough's high-income profile. Data on students with disabilities and English learners was not available in the source data, so a parent may want to ask the school directly about those populations and the supports available.
Kinnelon is a low-density, affluent commuter borough with no traditional downtown. Its housing market is expensive, with home values well above national and state benchmarks. The borough's population has been roughly stable in recent years after a period of decline. The school district did not have any major recent changes reported in available sources, such as budget votes, curriculum shifts, or referendums, that would be relevant to a parent considering the district.
For a family looking at Stonybrook, the picture is of a small, high-performing elementary school in an affluent, residential community where the housing market is a significant factor. The academic results are strong overall, particularly in math and ELA, and the school sits in a district that feeds into a middle and high school. The student body is not economically diverse, and the school's size means each grade has a modest number of students. A family considering this school should weigh the high cost of housing in Kinnelon against the consistently strong academic outcomes and the quiet, suburban, car-dependent character of the community.
