[quote=Anonymous][quote=Anonymous][quote=Anonymous]To provide the parents with the "improvement" their kids can get with the age-norm score, I'm sharing the CogAT results my kid got from GMU. My kid is not in FCPS, so no flaming please.
CogAT took at 2nd grade, age 7y  10m. The national grade score percentile is 85/99/94/98, national age score percentile is 84/99/93/98.
So the 10 month age difference lowed two of the subset score 1 percentile. 
On the other side, since the test was given in October, your Sept. kids probably can swing up  0.1 percentile, while the oldest kids  of 7y 10m probably should swing down 1 percentile, even if the county didn't age-norm it and you want to put it in.[/quote]

Oh yeah? How did you come up with .1 percentile? According to previous posts, a 45/48 NNAT raw score for a Nov. kid gave the same adjusted score as a 42/48 for a Sept. kid and the same percentile. Can you calculate the cumulative effect of such normalization on a composite score (CogAT) and the corresponding percentiles? No one said that a 60% would translate to an 80% but a 90% could go up to a 95% and that could make a difference for some kids...[/quote]

Agree that 0.1 percentile per month of age does not seem like enough. If 0.1 percentile per month were accurate, I could have had my 4-year-old take the test this year too and receive a score only 3.6 lower than my 7-year-old DC. Or maybe the 4-year-old would have scored higher!

But thank you poster for sharing the scores and trying to help provide some perspective and numbers to go by.[/quote]
