We are also in a very large district but not quite as large as yours. I do believe that if you went to high school 20-30 years ago, you would not have seen as many radically accelerated students.
LOL at your yardstick comment. If I had responded a couple of weeks ago, I would probably have said that I am likely a little off but I don't think I am that far off. After a recent discussion with DS' math teacher, however, I am not so sure. According to him, DS is far above the 5th graders who are in the Pre-Algebra program. In fact, he made the analogy that DS is as far above the 5th graders in the Pre-Algebra progam as those 5th graders are above the "regular" GT 5th graders who are working on 6th grade math. AS DS is only 9 and the other kids are 10 and 11, the difference is actually more profound. I am stil trying to get my mind around his comments because I had not shared any of DS' test scores and completely did not expect his opinion. I guess I am still somewhat stuck on the DS is actually a verbal kid rather than a mathy kid loop.
