New test "slightly" improves predictive power of SAT. But the problem is whether it is the nature of the particular new addition (which is the way it is being sold) or simply that you have more information in general. Increasing the length of any test, either the verbal or math portions, would have also provided more information and presumably improved the predictive power of the SAT. More questions would have given a more accurate estimate of how good the student is. Here is one of the articles on this new study:
The addition of a mandatory writing section to the SAT three years ago slightly improved the exam's ability to predict academic success for college freshmen, according to a report by the test's owner. . . .
The test now takes three hours and 45 minutes, which is 45 minutes longer than the old exam, and a perfect score is now 2400, up from 1600. The test-taking fee has risen from $29.50 to $45 over the last three years. . . . .
