There really is not a big difference. RC and RR are both AAP centers. MS AAP and MS Honors classes (which any kid can take) are fairly equivalent, taught by the same teaching teams. There may be small differences in world languages each school offers, and you can look that up. You can look up the school catalog (School Name Course Catalog)
You should mostly focus your attention on which HS you want your child to go to. Chantilly and Oakton are both excellent high schools. Chantilly is over capacity, however, and that might make a difference. Each school likely has different strengths and weaknesses in their various sports teams (for instance, Oakton swim and dive team is excellent), which may make a difference. Each school probably has slightly different course offerings, which you can also look up.
