<p>Schools don’t have enough data yet. They really don’t care about national statistics or whether other colleges find the writing scores helpful. They want data of their own about the students they admit. For a small school it can take quite a while to collect enough data to make sound correlations. For instance, the high school class of '06 was the first to submit SAT writing scores. 4-year graduation rates for this cohort are not known because 4 years haven’t elapsed since their matriculation.</p>
