<p>sry, my bad on the date. But, I’m still looking for evidence, any evidence, that the “…the relative strength of the testing group.” is part of CB’s equating.</p>
<p>According to CB:</p>
<p>
Every SAT includes a 25-minute section, which doesn’t count toward your final score. The test is created so that you won’t be able to tell which section this is. It may be a critical reading, mathematics, or multiple-choice writing section.</p>
<p>Since many different forms of the SAT are given each year, the unscored section adjusts for minor differences in difficulty across them. It ensures that a score of, say, 560 represents the same level of ability—regardless of what form of the test you take . This is another important part of making the SAT a standardized test.
</p>
<p>And:</p>
<p>
Equating adjusts for slight differences in difficulty between test editions, and ensures that a student’s score of, say, 450 on one edition of a test reflects the same ability as a score of 450 on another edition of the test.</p>
<p>Equating also ensures that a student’s score does not depend on how well others did on the same edition of the test.

<p>Do y’all think CB is telling incorrect truths?</p>
