The 2011 RIT Scale Norms chart had the percentile in one column 1 thru 99 and 8 columns for grades 3 thru 8 with corrisponding scores in those columns to match the percentile column. You could see where 99% started. Growth has been stale for 2 years as far as RIT score. I was just wondering how much has changed since 2011 as far as the 99% group (where it starts.)
It seems the median dropped a few points, at least as far as 7th grade. I was wondering where the ends of the curve were. Maybe they will provide something when they get more data.
Thanks for the link.
