[quote=Anonymous][quote=Anonymous]I havent found any new 2015 norms just this:

I've long been confused about these scores.  My 5th grader got a 263 in the math and I find it hard to believe he's so much above the mean for an 11th grader.   [/quote]

I don't think the 2015 complete norms have been released as they were in the 2011 format, with the many detailed percentile charts by grade.  But, you can still calculate a percentile score by using the mean for a particular grade and the standard deviation.  Basically, use the standard deviation to figure out how many standard deviations your child's score is away from the mean score for his grade, and then use a bell curve chart like this -- http://www.concordspedpac.org/Bell-curve-ss.htm  -- to approximate a percentile.

For the child above 263- 211.4 = 51.6.   And, 51.6/14.68 = approximately 3.5. Your child's score is 3.5 standard deviations away from the mean which is 99.9%ile.  (This is using the mean and standard deviation for the beginning of the year testing.)  263 is one and a half std deviations away from the 11th grade mean, which is approximately a 90-95%ile score in 11th grade.
