Islip Terrace sits in the center of Long Island and is only about an hour’s commute from the Big Apple. Largely residential, you’ll find townhome communities and apartment complexes as well as modest single-family homes for rent. Carleton Avenue houses delis, restaurants, shops and more, but most of Islip Terrace is a relatively laidback residential area. Families love the highly-rated schools in the area, and commuters will appreciate the Parkway that winds its way around the neighborhood, making it easy to explore the rest of Long Island by car. Neighboring communities hold a great number of restaurants choices and retail options, and the barrier islands and beaches are just minutes away to the south.

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.
