Some students who don’t take the SAT would score high
Actual and projected SAT scores for high-school seniors in 22 states where the SAT is commonly taken, 2000–2011. While the students who end up taking the test score higher on average than non-test-takers would, some non-test-takers would do quite well.
Note: projected scores based on PSAT results.
