You may have read of graduate schools dropping the use of the Graduate
Record Exam as a part of admission.

While it is true that the correlations between GRE performance and graduate
school performance are small (recent Science article), it does not mean
that what is measure by the GRE is irrelevant to grad school work.

I think was is going on, and always has gone on, is that you are dealing
with a restriction in range.  Imagine if you were to give the GRE to a
random sample of people and then measure their ability to do grad school
work. The correlation would be very high.  But people wanting to go to grad
school are mostly pretty smart - restricted range.

No correlation does not mean no importance of the traits being measured.

Give the restricted range, I cannot think that any test, present or future,
would be a good predictor.  The tests are not flawed; the samples are.
