The SATs Will Be Different Next Year, and That Could Be a Game-Changer

A few years ago, I started asking lecture halls filled with students to raise their hands if they had run out of time on the SAT. In each room, nearly every hand went up. I was surprised, but I shouldn’t have been.

For decades, educators have seen speed as a marker of aptitude or mastery, forcing students to scramble to finish tests. But a race against the clock doesn’t measure knowledge or intelligence. It assesses the much narrower skill of how well students reason under stress. As a result, timed tests underestimate the capabilities of countless students.

New evidence shows that although smarter people are faster at solving easy problems, they’re actually slower to finish difficult ones. They’re well aware that haste makes waste, and they don’t want to sacrifice accuracy for speed. You wouldn’t want a surgeon who rushes through a craniectomy, or an accountant who dashes through your taxes. Even for the many jobs in which people are judged on speed, there’s no evidence that doing algebra under time pressure is useful preparation. Although it pays to be quick, it also pays to be determined, disciplined and dependable.

Strangely, though, the tests that define students’ grades and help determine their educational and professional fates are rarely designed for deliberation. They evaluate students as if they’re applying to join a bomb squad or appear on “Jeopardy.” Time pressure rewards students who think fast and shallow — and punishes those who think slow and deep.

One fall, one of our daughters was pleasantly surprised by her grade on a math midterm. Despite being the longest and hardest test of the semester, it was her highest score. At first we were puzzled: She hadn’t changed her study habits or made a quantum leap in understanding. Then we learned that it was the first test where she didn’t feel pressed for time. Her teacher had allowed more time per question than usual.

On math tests, one of the few skills in which boys consistently outperform girls is mental rotation — turning 3-D shapes in their minds. But gender differences vary dramatically based on time pressure. Across several dozen studies, the more time students had to finish tests, the smaller the female disadvantage became. Shifting from short time limits to no time limits — or even just allowing more than 30 seconds per question — was enough to cut the gender gap in half.
