[IPAC-List] Reliability for T&Es

[Doverspike,Dennis]

This suggests I believe the logical problem with banding, especially based on reliability. Beyond the question of the psychometric basis. If you are really serious about it, why band based upon reliability, why not band based upon validity? Then, if we know the validity of T&E to be extremely low, the band range would be huge. Probably as wide as the score range. As a purely hypothetical question, if a test had perfect reliability but zero relationship with merit, what should the band be?

How about test-retest reliability?
