Original Research by School Decision on Nassau Co Juvenile Detention Center
The Nassau County Juvenile Detention Center, located in Westbury, is an alternative school operated as a county facility within the Westbury Union Free School District. The school serves middle-grade students and operates as a school of last resort for youth in the juvenile justice system.
The entity is currently listed as inactive in state records, meaning it is not presently operational. No enrollment, demographic, or academic performance data was available for this facility. Because this is a detention center rather than a traditional public school, many standard metrics do not apply. State testing results, graduation rates, attendance data, and program offerings were not reported. This is typical for alternative detention facilities, which operate under different accountability frameworks than conventional schools and may not be included in standard state reporting datasets.
Westbury itself is a transit-oriented suburb in Nassau County, roughly a half hour from Penn Station by Long Island Rail Road. The village is in active revitalization. Recent state-funded downtown improvements have strengthened pedestrian access between the LIRR station and the Post Avenue business core, and a large mixed-use rental development called The Cornerstone Westbury brought hundreds of new apartments to the area, including affordable units. More transit-oriented housing and commercial projects are in planning. Home values in the Westbury area are substantial and have been appreciating, placing the housing market in a moderate-to-high price range relative to national benchmarks. Rental markets are similarly expensive. This is a working and middle-class suburban community with diverse small employers, from banking to pharmaceuticals to retail.
The Westbury Union Free School District itself has made recent moves relevant to families. Beginning in the 2025-26 school year, the district expanded its universal pre-K program to offer full-day sessions alongside half-day options, tuition-free and with transportation, a meaningful addition for families with young children. In May 2026, district voters also approved the use of capital reserves for facility improvements and upgrades, addressing documented overcrowding issues. These steps signal district responsiveness to growth and learning-environment concerns.
For a parent or resident seeking information about the detention center itself, contact with the Westbury Union Free School District or Nassau County would be necessary, as the facility's current operational status, programming, staffing, and educational services are not detailed in available public data.
