MAP has no discontinue rule based on incorrect responses. It is a set number of items administered to each child, but in an adaptive item selection environment, with discontinuation based only on completing your quota of items.
DIBELS is primarily aimed at lower elementary (the whole range is K-6), with at-risk/below-grade-level students its principal population.
NWF=nonsense word fluency, a measure of phonetic decoding skills. At the 2nd grade level, it consists largely of VC and CVC pseudowords (V=short vowel, C=consonant).
(D)ORF=oral reading fluency, a measure of reading speed, and (surprisingly) the best quick measure of reading comprehension.
WR=most likely grade level word lists, including high-frequency words (e.g., Dolch words for first or second grade).
You may find this benchmarking document of interest:
https://dibels.uoregon.edu/docs/DIBELSNextRecommendedBenchmarkGoals.pdfNote especially that the last page, where the 6th grade benchmarks are, indicates that she has met all of them. I would suggest that this may be useful data for advocacy.
