Original Research by School Decision on Union High School
Union High School is a regular public high school serving grades nine through twelve in the Township of Union School District, located in Union, New Jersey. It is the district’s sole comprehensive high school, and its enrollment is large, placing it among the bigger high schools in Union County. The student body is racially and economically diverse: Black and Hispanic students together account for a substantial majority of enrollment, with Asian and white students each making up a smaller but notable share. Just under half of students qualify for free or reduced-price lunch, giving the school a meaningful measure of income diversity that is common in many New Jersey suburbs with a mix of housing types.
State assessment results and the four-year graduation rate were not available in the data used for this profile. That absence is worth noting because it leaves the strongest public measures of academic performance unaccounted for. A family looking at Union High School will want to seek out these figures directly from the district or state report cards to get a clear picture of proficiency levels and how many students graduate on time. Without them, it is not possible to position the school’s academic outcomes relative to other high schools in Union County or across New Jersey. The comparison data that does exist flagged those metrics as not applicable because the values were missing, so the school’s performance in these areas is simply unknown from this source.
What is known is the broader environment. Union Township is a densely settled suburban community traversed by major highways and rail lines, with a mix of residential neighborhoods, commercial corridors, light industrial zones, and a downtown area. Kean University is located within the township and serves as a major institution and employer. The township’s population has grown steadily over recent years, and the housing market reflects that demand: home values are on the higher side relative to national medians, and rents are also elevated, which means the local housing market is competitive. That economic context sits alongside the fact that a significant share of the high school’s families qualify for income-based meal assistance, pointing to a community that includes both upper-middle-income households and those with more modest resources.
On the district front, two recent developments are relevant. In late 2023, voters approved a capital referendum to fund roof replacements, security vestibules, HVAC upgrades, and other improvements across all district schools. Those projects are underway and will affect facilities at the high school as well. Separately, the district implemented a reorganization plan in fall 2025 that shifts grade configurations across its elementary and middle schools. For high school families, the most direct effect may be that the feeder patterns are changing, so families with younger children should be aware that school assignments at the lower levels are in flux.
The school itself has no specialized designation — it is a standard public high school, not a charter or magnet. Information on course offerings, advanced placement, dual enrollment, career and technical programs, and extracurricular breadth was not available in the data reviewed. That is another gap a prospective family would want to investigate: the range of academic pathways and support services offered to a student body of this size can vary widely.
Union High School is a large, diverse high school in a growing suburban township with a mixed economic base. The lack of published test scores and graduation rates makes it difficult to assess the academic floor or ceiling from this profile alone. A parent considering this school would be well served to visit, talk to current students and staff, and review the state’s school performance report for the concrete numbers that are missing here.
