Yes, Cricket that happened for us too. I think it's lame that NWEA went back and changed the 2009 data to match the 2011 norms. How did my kid get normed to a group of data that didn't exist at the time.
He apparently got dumber retroactively ;-)
What I did notice was that the top end has a wider spread and 99th percentile seems to be further out there than it was before. On one hand, this is good because they are recognizing the top end. On the other, it is a little frustrating for advocacy because I can hear the teacher now saying "He's not 99th percentile for the next grade up anymore, see right here?" Well just because you changed the data, doesn't mean you taught him anything this year!
