I live in DC and have an 8 year old who attends a DCPS. We love the neighborhoods east of the park – Columbia Heights, Adams Morgan, and Mt. Pleasant. We have lived in Columbia Heights for about 9 years. We were lucky enough to get a seat in the public school lottery so our child could attend a school outside of our neighborhood, as our neighborhood school really wasn’t an option.
I would advise you use this resource with caution but there is a local www site called DC Urban Moms & Dads – lots of trash, lots of drama but it does provide a taste of what the scene can be like here. If you can afford private – GDS (Georgetown Day School) might be of interest to you as well.
Best of luck with your move to DC!
