I have had children taking the NWEA MAP for a few years now. While I do find the overall RIT score somewhat interesting, the score breakdowns seems more useful in terms of offering information to aid in the child's learning.
For math, there is a range score in the areas of number sense/computation/operations, patterns/functions/algebra, data/statistics/probility, and spatial sense/geometry/measurement.
In reading, the categories are word recognition/analysis/vocabulary expansion, comprehension/informational, comprehension/narrative, and literature.
Our school district has on-line learning tools for each range but not for the general RIT average score. For example, a child with a literature range of 206-222 can go onto the school website and do literature activities in the range of 200-210, 211-220, etc...
