Also, did we ever fully answer the K-2nd MAP question? Is it truly "above level"?
My understanding is that MAP doesn't give GE's. It gives a RIT score which is an equal-interval scale (like inches on a yardstick) that's independent of grade level. If you took MAP for Primary Grades (K-2) and had a RIT score of 167, the K percentile would be 94%, 1st grade percentile would be 50%, and 2nd grade percentile would be 16%. I haven't seen any data showing a 2nd grader would get the same RIT score whether he took either the MAP for Primary Grades (K-2) or the Measures for Academic Progress Test (2-11). Since it's an equal-interval scale, that should be the case.
It seems like a case could be made for using MAP for an assessment of aptitude for the IAS. The nature of the test allows the questions to get harder and harder, i.e. the ceiling is not limited by grade. The IAS authors acknowledge the achievement tests listed are not exhaustive. Maybe that's true of the aptitude tests too. It might be worth contacting the Blank International Center for Gifted Education and Talented Development directly to find out about MAP and the IAS: 1(800) 336-6463. If you do, let us know!
