Why does the District Summary by Grade reports appear to group by test name for math, but not for reading?
The District Summary by Grade report groups results based on the goal structure of the tests. Because the goal structures of the math 25 and 6+ tests are different, those test results are grouped separately on this report. The reading 25 and 6+ tests, however, have the same goal structure and therefore their test results are grouped together on this report.
NWEA has prepared Goal Structure Charts for most states through an alignment process that links state standards documents to the NWEA item bank. The differences between the sub-goals in the math and reading subject areas is illustrated clearly in this document. The Goal Structure Charts are available in our State Information area. DesCartes: A Continuum of Learning can also be used to find more information about the sub-goals included in each reported goal area.
In math there are different sub-goals in the 25 tests than in the 6+ tests. For example, the reported goal area of Geometry for the 25 test might contain the sub-goals of points, lines and angles; two and three dimensional shapes; and similar, congruent, symmetry, and transformations. The 6+ test will always assess those sub-goals, but might also include Pythagorean theorem, relationships, and vectors.
In reading, both the 25 test and 6+ tests assess the same goals and sub-goals. The differences between the two tests are in length and/or difficulty of the passages on which the items are based. In language there is only one test, and therefore one set of goals and sub-goals.
