Gifted Issues Discussion homepage Forums Identification, Testing & Assessment What's a "normal curve equivalent"

Ok, so I'm kind of slow with this. I'm assuming that the percentile ranking is more meaningful than the NCE? And what does it mean if they are the same with DS (everything is a 99) but with DD the NCEs are a lot lower (5 to 10 points)? So for instance for math her percentile ranking was 98 (she was unmedicated and her scores dropped a lot), but NCE was more like 90 or 93.
