Tom, to give you the best anser on schools your best doing the research on your own. As a Realtor we are unable and SHOULD not comment on schools or the demographics on any area. If you google the schools you should be able to find all the information your looking for.
You can go to my site http://www.southnewjerseyhomes.com to get free school reports. Sicklerville schools are not that great neither are they that poor IMO. I do a good bit of business in Sicklerville and that's one of the things I advise. The neighboring town Gloucester Twp has the same values and much better schools. What you have to remember is that Sicklerville has quite a few low market town home communities where they are predominately investment owned which attracts a large number of renters. Lack of home ownership as well as sub $100k market values makes for the same learning environment as you have in the city where home values are the same. If you will like additional info send me an email or call direct. I'd be happy to assist.
