Lake Grove is a small incorporated village in Suffolk County, sitting near the center of Long Island in the Town of Brookhaven. Settled in the early 18th century along what is now Middle Country Road, the community earned its name from the groves of trees near Lake Ronkonkoma and officially became a village in 1968. Its historic First Congregational Church of New Village, built in 1818 and listed on the National Register of Historic Places, still stands today and appears on the village seal. Stony Brook University anchors the surrounding area educationally and economically, drawing a steady flow of activity to nearby corridors. Smith Haven Mall, one of central Long Island's most established retail destinations, sits within the village and has served the region since 1969. The rental landscape here is primarily made up of apartment communities offering spacious floor plans with traditional suburban settings, complemented by townhome-style options. Access to the Long Island Expressway and proximity to the Long Island Rail Road station in Lake Ronkonkoma keep New York City within reasonable reach for commuters.

The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.
