Psychologists debate the meaning
of students’ falling SAT scores
New research finds that 57 percent of 2012 SAT test takers did not score
high enough to indicate likely success in college, according to the College
Board, the organization that administers the test. Overall test scores
declined from 2006 levels among nearly every demographic group, and

reading scores hit a four-decade low, says College Board President Gaston
Caperton. That, he says, should serve as “a call to action” to increase the
rigor in America’s schools.
A call to action is especially needed given new research that
finds SAT scores do predict college success, even when controlling
for socioeconomic status and other factors (Psychological Science,
September). In the study, researchers examined data from 143,606
students at 110 colleges and universities collected by the College
Board for 2006 — the first year of the revised SAT — as well as data
from the University of California system from 1995 to 1997. They
examined students’ test scores, grade point averages in high school
and the freshman year of college, and socioeconomic status (SES).
The researchers found that even after controlling for family income
and parents’ education, both the SAT score and high school grades
contributed to predicting freshman-year college performance.
The researchers also found that the college students’ SES was similar
to the SES of students who were applying to college, suggesting that lowSES students may be underrepresented in colleges because few apply.
“Our findings suggest that one remedy for under-representation
of lower SES students can be found in addressing barriers to students’
entering the admissions process,” says Paul Sackett, PhD, the study’s lead
author and a psychology professor at the University of Minnesota.
