TGB: Validity is a much more complex issue than that; Rasch will help, but good 
theory driven item development t is a prerequisite.
GS:I would like to highlight the notion that validity is essentially an evaluative 
process using measurement and statistical operations as support. 

Agreed, indeed, Gregory.
