Recent news about major changes to the SAT hit just as I was boarding a plane home from a business trip. I took advantage of my time in the air to read up on the media reaction to this announcement. My ultimate take, despite what is asserted in the New York Times, is that these changes help the test prep industry hone in on how best to help students do well on the SAT, which will in turn help test prep become even more reliable in terms of results.
For example, since the reading passages now can be more accurately predicted, tutors can prep kids specifically for those pieces. If the College Board is limiting the number of vocabulary words, tutors may direct students to study a few hundred rather than a few thousand. If they are focusing the math section by narrowing the amount of topics covered, that also helps the tutors concentrate their efforts.
