I grew up in that area and my family still live there, but I don't personally have kids in the schools. I have nieces and nephews, and tons of friends with kids all around that area.
The elementary and middle schools are good. Reservoir High is a fairly new high school, and it hasn't been the best. It's not horrible, but it doesn't have as high a graduation rate as most high schools in the county, fewer kids go on to college, and there are some discipline/security issues. Another neighborhood, Hammond Village (close by but with much older homes), feeds into Atholton High, which gets good ratings/scores.
