<p>If you like Fairfax County schools, the "best" schools, test-score wise are Langley (McLean), McLean HS, James Madison HS (Vienna), and Woodson HS (Fairfax). They are about 10-15 miles west of DC, and their student bodies are between 1,800-2,100 kids. I won't mention TJ because it's a magnet school and they won't accept incoming juniors I believe. Robinson, Westfield, and Lake Braddock are all good schools but have student bodies at over 3,000 each. The only bad part about homes in Fairfax County is price, where a regular sized 4 BR house (2,500 sq. feet) in McLean can cost nearly 1 million bucks, but the same house 25 miles west will be a mere fraction of that. </p>
<p>You also need to be aware that not every high school in Fairfax County is a super performer on the SAT's, etc. Schools such as Stuart, Falls Church, and Mount Vernon are all close to Washington, DC, and are Fairfax County's "low performing schools", but even their scores are around national averages. Diversity also can vary greatly. For example some schools have a very high concentration of White students, but others have high concentrations of Asian students (mostly Koreans and Chinese) and others with Hispanics. You can't really judge any school until you see it for yourself.</p>
<p>If price of homes become an issue, you may want to move to Loudoun County, Virginia, Fairfax County's western neighbor, which is where Dulles Airport is (and further west). Homes are cheaper there, and they have a good school system too. There is no clear "best" school, but it is sprawling like crazy, and their schools are smaller since they split schools often, but it means less competition too if that's a factor. Loudoun schools are about 20-50 miles west of DC depending on which school it is.</p>
<p>You said your daughter is a cheerleader, and if she's real good at it, you may want to consider moving to Stone Bridge HS's zone if the commute isn't too much (eastern Loudoun County). They won the AAA state championship three years in a row.</p>
