<p>I made an arbitrary value of supposed test takers who are “not college bound” and removed them from the total population of ACT test takers. The deduction in score relative to the SAT is small (10 SAT points), regardless of how large the population I remove to about ~200,000 people.</p>
<p>A composite of 34:</p>
<p>1 - (13084/1568835) = .9916</p>
<p>Arbitrary removal of 100,000 people (just for an example):</p>
<p>1- (13084/1468835) = .9911</p>
<p>difference: .00056</p>
<p>This difference yields a comparable score of 2250, rather than 2260 with 100,000 people removed from the total ACT population. </p>
<p>~400,000 people are in mandated states, so an assumption that 25% would not have taken the ACT would result in a 10 points decrease at higher level ACT scores.</p>
<p>This is already reflected in the ACT-SAT concordance table.</p>
