Reading scores on the SAT for the high school class of 2012 reached a four-decade low, putting a punctuation mark on a gradual decline in the ability of college-bound teens to read passages and answer questions about sentence structure, vocabulary and meaning on the college entrance exam.
Many experts attribute the continued decline to record numbers of students taking the test, including about one-quarter from low-income backgrounds. There are many factors that can affect how well a student scores on the SAT, but few are as strongly correlated as family income.
Scores among every racial group except for those of Asian descent declined from 2006 levels. A majority of test takers - 57 percent - did not score high enough to indicate likely success in college, according to the College Board, the organization that administers the test.
The national trend lines are alarming and should serve as "a call to action," College Board President Gaston Caperton said. "When less than half of kids who want to go to college are prepared to do so, that system is failing."
The nearly four-hour SAT covers critical reading, writing and math. Each subject is worth a maximum of 800 points, for a potential total of 2400 points. For generations, SAT scores have been used, in conjunction with grade-point averages, by college admission officers to judge whether an applicant is likely to succeed at their school.
But questions about whether the SAT is biased in favor of middle-class and wealthy students have led many colleges and universities to use other gauges or to accept an alternative exam, the ACT, which edged out the SAT in 2012 for the first time as the nation's most popular college entrance exam.
There is a significant correlation between family income and test scores on the SAT, with average scores increasing with every $20,000 in additional family income.
Educational experts are divided over the causes. Some assert that privileged students do better on the SAT because they are exposed to activities, from summer camp to private violin lessons, that give them an advantage. Others point to the fact that affluent parents can provide private tutoring and privileged students can afford to take the test multiple times.
Still, many school districts - and parents - traditionally have seen SAT scores as an important measure of the quality of a K-12 education.
Across the country, 1.66 million seniors who graduated last June took the SAT, the highest number since the exam was first administered in 1926.
The average reading score for the 2012 graduating class was 496, down one point from the previous year and 34 points since 1972. The average score on the writing portion was 488, down nine points since that subject was first tested in 2006. Math scores were flat at 514, compared with 2011.
In Arizona, the average reading score was 517, the average score on writing was 499 and the average math score was 525.
State-by-state comparisons are invalid since student participation in the SATs varies across all states.
More than a quarter of students in public schools who took the test - 27 percent - came from families with income low enough to qualify for a waiver of the $50 test fee.
More than a third of all test takers reported that their parents had not attended college.
The 2012 SAT scores come after a decade of efforts to raise test scores under the No Child Left Behind law, the federal education initiative crafted by President George W. Bush. Critics say the law failed to address the barriers faced by many test takers.
"Some kids are coming to school hungry, some without the health care they need, without the vocabulary that middle-class kids come to school with, even in kindergarten," said Helen Ladd, a professor of public policy and economics at Duke University.
"If we really want to do something to close achievement gaps and raise test scores, we have to ... start addressing this issue."
