Students like Ian Haimowitz, a sophomore at George Washington University, a test-optional school in Washington D.C.
He says in the beginning, he felt like a fish out of water.
"I know for a fact I'm the first Nicaraguan-American, the first Latino, the first Jewish Latino that a lot of kids meet," he says.
He adds that when he arrived at GW, he looked around and asked himself, "What am I doing here with kids who went to private schools and got the best education possible?"
It was a very different world than he grew up in back in New Mexico.
"I remember my freshman year of high school, I didn't have a math teacher. Maybe that's why you see in my test score that I didn't have a good grounding in math. But I believed my potential was still there."
Ian was a straight-A student in high school, but his SAT scores were so low he didn't think any top tier school would accept him. He says not having to submit his test scores opened the doors to a top selective school.
This year, George Washington received about 26,500 undergraduate applications from all over the country. Close to 20 percent did not submit their test scores, which GW says has helped enroll more students from diverse backgrounds.
Still, some researchers question the impact that test-optional admissions policies have had on schools.
Jack Buckley, a senior vice president at the American Institutes for Research, notes that while diversity improved at schools that have gone test-optional, that also happened "at the same rate among those that didn't."
In other words, says Buckley, test-optional schools are not more effective in enrolling minorities than schools that still require test scores.
Syverson says that's not what the evidence in his study is showing. "We certainly are not arguing that everyone should abolish test scores," he says. "Test scores do have some value."
Syverson insists that his study shows that tests can be an obstacle not just for students who don't test well, but for students from under-served, under-represented populations.
More importantly, he adds, you can admit pretty good students by looking at something other than test scores.
That's been the experience at George Washington University. "Our experience is actually that (students') high school performance predicts college performance extremely well," says Forrest Maltzman, the university's provost and chief academic officer.
Maltzman says that whatever helped students be successful in high school tends to work for them in college: "Standardized tests don't get at that."
Two years worth of data show that students who got into GW with high test scores performed no better as freshman and sophomores than those who got in without submitting their test scores, he says.
"The added value of test scores in predicting performance today is really very very minimal," Maltzman argues. "The best thing these tests match up with is actually family income."
And that, says Syverson, is consistent with his team's findings. Still, he cautions that test optional policies are no panacea. They're just another way to make college more accessible.
