Here is the spread sheet. If the link doesn't work just try searching on the forum as I did. It says that Sidwell has a 700 average SAT which is the best in DC, but not by that much. Other schools in other cities - NY - have higher average scores. As I said before, it's consistent with my understanding of about how kids at the school perform.
That's my spreadsheet, so I'll comment. I am highly confident of the accuracy of most numbers on there, because I carefully gathered them from trustworthy sources. However, although I still have fair confidence in the SAT score averages, those are the least trustworthy of the bunch. Different schools and other sources report SAT averages, but they are often reported in varying formats. For example, one school might report the mean SAT, another reports median, and another reports a range for the middle 50%. Also, I sometimes pick and choose among non-school sources, because many have questionable credibility. For example, if someone posts a list of SAT averages on College Confidential, I won't trust it unless I can independently verify the accuracy.
That 1400 average for Sidwell has always been itchy for me. It's only based on one source, a Washington Examiner article from the early 2000s. In my experience, Sidwell simply does not release information to the public; they are more private than any other school I investigated. I find it quite frustrating, but I have grown to respect them for it. Nevertheless, I think it's reasonably accurate because it's consistent with all the other data for that school. I'm happy to see a Sidwell parent with actual inside info confirm that it seems fairly accurate.
That's all I can add. I hope it helps minimize any disagreement.
[ETA: The Sidwell college success number also has a shaky basis IMO, because it's a mathematical calculation without multiple years of data to support it. But again, it's consistent with other data on Sidwell, so I consider it reasonably accurate.]
