I posted those schools due to the statement made by beachmouse:
As for the percent meeting standards in 10th grade reading, this year's FCAT had 61% listed, which is still not ideal but not too far from what are seen as the good general enrollment high schools in the Panhandle that have students that regularly send kids to Ivies (Gulf Breeze, Niceville, Navarre)
One of our sons attended Duke and I can assure you that an SAT score of 1490 would not have gotten him there. He worked hard, and we set a high level of expectation.
The point being that some of the good reputation schools that do routinely have students who throw out good test numbers on the good pointy end of the bell curve aren't that different than SWHS on the metric that the very first post brought up.
And while averages present one aspect of a school, it's also helpful to know medians and general distributions of scores because there are frequently groups that will skew a simple average one way or another and may lead to conclusions that don't reflect a population as a whole, or fail to recognize a successful subgroup (example here- kids that take X number of AP classes) within the big group.
