[quote=Anonymous][quote=Anonymous]I think a lot of you are making a big deal out of nothing.  The percentiles for the Map 2-5 and 6+ are based on the RIT score.  The RIT is supposed to show growth, the tests have overlap, one just goes lower and the other extends higher.

Here is how NWEA defines the RIT score:

What are the characteristics of the RIT scales?

These RIT scales are stable, equal interval scales that use individual item difficulty values to measure student achievement independent of grade level (that is, across grades). "Equal interval" means that the difference between scores is the same regardless of whether a student is at the top, bottom, or middle of the RIT scale. "Stable" means that the scores on the same scale from different students, or from the same students at different times, can be directly compared, even though different sets of test items are administered. A RIT score also has the same meaning regardless of the grade or age of the student.

In summary, the RIT scale is:
An achievement scale
Accurate
Equal interval
Useful for measuring growth over time
The same regardless of the grade or age of the student

I think a lot of people are making a big deal of MAP 6+ when there’s very little in formation on what results actually mean and what content is being tested. For example I could never find if MAP is testing precalculus (what topics exactly).

Often parents post their middle school students scores in the 99 percentile for 12 graders, but it’s really obvious there are are very few students capable of this feat. I have some serious doubts on accuracy and grade and age independence of the test, as used by the district.

I get most people care about MAP for math placement, but I find it odd that the placement doesn’t even follow the NWEA guidelines for Algebra readiness.

Other tests used for placement like IAAT or MDTP are much more transparent with the contents and interpretation of the results.
