Center Grove School, Randolph NJ

Original Research by School Decision on Center Grove School

Center Grove School is a regular public elementary school in the Randolph Township School District, serving students from pre-K through fifth grade. It is one of four elementary schools in the district, each located in a different neighborhood of this spread-out suburban township. The school’s academic record on state assessments is strong, and the community it serves is notably affluent, with a very low share of students qualifying for free or reduced-price lunch.

On the New Jersey Student Learning Assessment, Center Grove’s students posted solid proficiency rates across tested grades and subjects. In both math and English language arts, the share of students scoring at or above the proficient level rose steadily from third through fifth grade, with fifth-grade results reaching the highest levels in the school. Science proficiency, which is tested only in fifth grade, was somewhat lower than the math and ELA results. Overall, the school’s combined proficiency index places it in the top quartile relative to districts across Morris County, a clear indicator of strong academic performance for an elementary school.

The student body is moderately sized. The majority of students are white, with a substantial Hispanic population and smaller shares of Asian, Black, and multiracial students. The very low rate of economic disadvantage suggests that the school draws from a relatively high-income attendance zone. Data on the share of students with disabilities and those learning English was not available in the records reviewed, so families who need specific information about special education or English learner services would want to ask the school directly.

Randolph itself is a 21-square-mile township that the state planning commission designates as half rural, half suburban. It functions as a residential suburb of New York City, with commercial activity concentrated along the Route 10 corridor and no traditional downtown. The township’s schools, civic buildings, and the County College of Morris campus are spread across the area rather than clustered in a single center. The housing market is expensive, with home values well above national and state averages, reflecting the area’s desirability and the quality of its schools. Population growth has been steady but modest, and the township has been recognized in regional rankings for its schools, home ownership rates, and safety.

The district itself has not seen any major recent changes that publicly reported sources captured, suggesting a period of stability in leadership, programs, or facilities. That stability, combined with the school’s strong test results and low poverty rate, paints a picture of a well-resourced elementary school in a community with high demand for its housing. Families moving to the area should expect high housing costs and a car-dependent layout, but they will find an elementary school with a track record of solid academic outcomes and a peer environment that reflects the area’s relative affluence.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
