An ETS report "Teacher Quality in a Changing Policy Landscape:
Improvements in the Teacher Pool"
http://www.ets.org/Media/Education_Topics/pdf/TQ_full_report.pdf has statistics on average SAT scores of teachers licensed in certain subjects.
According to Figure 20 "SAT Verbal Scores by Licensing Area for Those Passing Praxis Test" the average SAT-V scores in the period 2002-2005 for middle and high school teachers of academic subjects (math, social studies, foreign language, science, and English) was in the range of about 560 to 580, and Figure 21 shows average SAT math scores of about 570 and 590 for science and math teachers.
These scores are above the averages for college graduates (543 and 542 for SAT-V and SAT-M), but they are below what many gifted students achieve in 7th and 8th grade. I think students should have teachers who have more developed academic abilities than they do, which argues for accelerating into college courses students that are scoring in the 700s on the SAT-V and SAT-M. This assumes that the average scores of college teachers are higher.
