<p>That College Board equivalency table is basically what all the tables you find on the web are copies of. The problem is you have to read the small print on that College Board site, where it says at the bottom:</p>
<p>"Data are based on 103,525 test takers who took both the SAT I and the ACT Assessment between October 1994 and December 1996."</p>
<p>In other words, all it shows is the percentile equivalencies that existed in the mid-1990's and then only for persons who took both tests. The College Board does not claim it has any accuracy today or should be used by any college for the purpose of determining equivalences. Despite that some colleges do still use it for that purpose; however, many create their own equivalency tables based on more modern data and many do not even try to equate the two. If you want to see how a college actually weighs the scores of each test for admission, you need to see what the middle 50% range is for each college for those admitted with the tests. Examples: Stanford's middle 50% range is 1340 to 1560 SAT and 28 to 34 ACT, which is closer to the actual percentile comparisons that would exist today using modern data. Also if you want to see the actual percentile spreads for the SAT and ACT for 2004 admittees go to the following:</p>
