A meta-analysis of the GRE's validity in predicting graduate school success
found a correlation of .3 to .4 between the GRE and both first year and overall
graduate GPA. The correlation between GRE score and graduate school completion
rates ranged from .11 (for the now defunct analytical section) to .39 (for the
GRE subject test).
Currently the GRE Scores are valid for 5 years.
Plans for the revised GRE

The announcement cited concerns over the ability to provide clear and equal
access to the new test after the planned change as an explanation for the
cancellation. They did state, however, that they do plan "to implement many of
the planned test content improvements in the future", although exact details
regarding those changes have not yet been announced.

changes mostly center on "fill in the blank" type answers for both the math and
vocabulary sections that require the test-taker to fill in the blank directly,
without being able to choose from a multiple choice list of answers. ETS
currently plans to introduce two of these new types of questions in each
qualitative or vocabulary section, while the majority of questions will
presented in the regular format.
On January 2008, the the Reading Comprehension within the verbal sections has
been reformatted, passages's "line numbers will be replaced with highlighting
when necessary in order to focus the test taker on specific information in the
passage" to "help students more easily find the pertinent information in reading
