BTW, there are two different kinds of reading tests: STAR progress monitoring tests, which stand alone, and AR reading comprehension tests, which are specific to the book. The psychometric data in the technical manuals refer to the STAR test, not the book tests.

And the SEM for the 95th %ile is 84 for grade 3, and 111 for grade 4. So huge, for high achievers.
