> but AIUI SAT scores are quite stable over time.) No. There was a major test format change a few years ago, in addition to students becoming more qualified in general. Reading scores moved from a mean of 500 to 529. Math scores have moved from a mean of 515 to 521. There's been a 35 point progression in the mean in that time. > for those taking the SAT in their final year of high school Yes, but a very large proportion of people just use their early junior year SAT score. So you're comparing a "final year of high school" vs "whatever year teachers took it in" > From the paper you quoted, the average score for teachers is 1030 or 1064, depending on what you look at You're missing the point of the paper. The people who actually progress to teach have a higher score than those who obtain a credential (many of whom do not successfully enter the teaching profession). And, of course, note that teachers in desirable districts are substantially above the mean.
