[quote=Anonymous][quote=Anonymous]The bell curve mean is 100. 2 sigma (Standard Deviations) above mean is 97%-98%. NNAT2 SD is 16, while NNAT SD and Cogat SD are 15. So 132 of NNAT2 is same percentile as 130 NNAT. That is national rank. Are FCPS kids scored higher? Maybe, I didn't find the statistic data of FCPS. In the letter from DC school, 105 is the mean. If that is true mean, 137 NNAT would be 98% in FCPS 1st graders.[/quote] Mumbo jumbo, Fairfax kids aren't "scored higher", but they do score higher than the national pool (more smart kids live in Fairfax than in other regions of the country).
