Hi Kai. Thanks for the informative paper. This was my concern with the screening process in my district. I reached out to the person who heads the program as well as the assistant superintendent of curriculum in order to voice my concerns. They informed me that the process was changed a few years ago to this two step process, i.e. the wide-net step (CogAT) and admission step (SAGES). I was also told that I live in a high-achieving district and that 99%-ile scores are more common than I think. My response was that even if 99%-ile scores were being achieved at 3-5 times the normed rate (which would belie the statistics of this psychometric instrument) that would match the admission rate to this program precisely.
