The commentary on Jack Kaplan's study asserts that the main message from Kaplan's study is that the quality of SAT coaching matters. Coaching that is above average in quality should be expected to produce associated score gains that are also above average. This is an intuitively plausible argument, and the results from Kaplan's study are suggestive along these lines. The commentary also submits, however, that beyond intuitive appeal, there is a dearth of evidence to make this argument empirically compelling.
