There are 3 towns that make up the Northern Valley - Demarest High School as I would think you'd know - Closter, Demarest and Haworth. You sure don't need to call up a real estate agent to check out all 3 - the best school data comes directly from the State of New Jersey. Go to the NJ State School Report Card at http://education.state.nj.us/rc/rc08/index.html New Jersey updates this data annually and you'll find 2008's there now. However, data alone doesn't tell the entire story - you may want to ask if you could visit the schools. This is the advice I give all my customers and I have this on my website. You can also go to each school district's website as well -
Closter - http://closterpublicschools.schoolwires.net/closterpublicsch…
Demarest - http://www.nvnet.org/k8/demarest/index.html
Haworth - http://www.haworth.k12.ok.us

That is a tough question! All of the elementary / middle schools are rated highly. Call me and I will get you details for each of the schools. Do you require a special needs program? Is there a need for specific foreign languages, sports, etc?
