We have had a very positive experience at Halley. I do not believe this website's scores do the school justice. Halley has a very diverse population of students. There are a good number of students who are special needs/education (Halley is one of the few FCPS with a special needs pre-school) and who are ESOL. If you look at the VA state SOL scores, these are the population groups who most lag on SOL scores, especially in elementary school. The scores for these groups are not a reflection of the school, teachers, or even the students; but rather on the SOL's themselves. Halley has something for everyone, including a Level IV Advanced Academics program.
