Prior research suggests that ImPACT's existing system
of validity checks, which flag suspicious scores on five individual subtests, detect just 65 to 70 percent of sandbaggers.
By contrast, the reviewed study has put clear evidence on the table, and shown that it is robust to a forceful set
of validity checks (the more demanding of which are not even discussed in the review).
If it offers testing and
validity checks to see whether it fits your specific needs, try it before you buy it.
This is not a charge, but
a validity check on your card to guarantee your booking.
They can provide you a genuine perspective on their day to day work, be
a validity check on your sourced information and even also become the person who refers you into an available vacancy!
