You might check with her teacher to confirm whether the NWEA tests she took last Spring and this Fall are aligned with the Common Core.
NWEA now has a version of the assessment which is aligned with the common core rather than individual state standards. During the transition period, I believe that districts can choose which version of the test they want to use. As such you could have a situation where the tests taken last Spring were under the older standards and now this Fall being aligned with Common Core, which could cause a slight dip in the scores.
