For all schools, but particularly those in Durham, you really MUST visit. The scorecards and especially the "great schools" score that trulia uses arent representative of the actual quality of the education you get. We love Parkwood. I have five children. There is a very active PTA as well as a great new principal there who plans to stay long term. However, there is a very high ESL population and a high rate of poverty, which are factors that have a detrimental effect on the ratings despite the fact that the teachers and staff are wonderful and the students make great strides.
Parkwood Elementary school is considered to be a good school by most of the people I speak with here in Durham. I have attached a link below to what I consdier to be the best site for hard data on all the schools here in the state. Feel free to contact me through my Trulia profile if you have addtional questions.
