I can tell you that Plainedge has invested quite a lot of money in their schools recently and built a beautiful brand new Middle School on Stewart Ave. in Bethpage.
In addition, I agree with Arlynn regarding the site search: http://www.GreatSchools.net.
Her suggestion will allow you to plug in local school districts, check each one off, then press the "compare" button. The site does all the work.
And, finally, I thought you might be interested to see that Newsweek named Plainedge H.S. as one of America's best! I copied and pasted an excerpt below.
Good luck with your search, and, as always, feel free to contact me with any questions or real estate help you may need! Keep me posted on your progress!
Plainedge HS One of Newsweekâ€™s Best
Plainedge High School is among the schools listed in Newsweek magazineâ€™s annual coverage of â€œAmericaâ€™s Best High Schools.â€ Newsweek makes its determination by looking at an index based on the number of AP exams taken, divided by the number of the graduating seniors. Any public high school that has an index of 1 or greater is included in the feature. Once again this year, Plainedge High School made the listâ€”with an index of 1.3, Plainedge High ranks 1,249 out of approximately 67,000 public high schools in the United States. Only about 1,600 schools made Newsweekâ€™s list. Congratulations to all of the faculty and staff and especially to the students who helped us achieve this wonderful distinction.
