Does GPA or Test Scores Matter More for College Admissions?

Grades matter more. Across colleges, admissions offices weigh GPA and the rigor of your course load most heavily, and high school GPA predicts college graduation better than test scores do. But as the question of whether GPA or SAT matters more continues to arise, it’s clear that test scores are becoming more important again, especially at selective schools. If you’re applying to reach schools, plan to test. Test-optional usually means test-preferred.

I’ve been doing this for 27 years, and it’s the question I get asked earliest and most often. The honest answer has two halves, and most advice out there gives you only one.

Do Colleges Care More About GPA or Test Scores?

GPA, and it isn’t especially close at most schools.

Colleges publish how they weigh each part of an application, rating factors from very important down to not considered. The same pattern shows up almost everywhere: academic GPA and rigor of secondary school record sit at the top, and test scores sit somewhere below them. Our counselors read those filings for every school on a student’s list, which is a better use of an afternoon than any ranking. We break the full set down in our post on the most important factors in college admissions.

What has changed is the second half of the answer. Test scores are climbing back up that list, and at the most selective schools they’ve climbed a long way. Test-optional is very good branding, but what it usually describes is a policy where a score is not required, and a good one still helps, which is why I tell families to read it as test-preferred instead.

In our own caseload, the pattern is consistent: a large share of applicants skip the score, and far fewer of the students who get into the most selective schools on their lists do. We cover the mechanics in what test-optional really means.

Why Is GPA a Better Predictor of College Graduation?

Because a GPA is three and a half years of evidence and a test score is one Saturday morning. Researchers at the University of Chicago tracked 55,083 students who finished high school in Chicago and enrolled at four-year colleges, and found that high school GPA was about five times stronger than the ACT at predicting whether those students actually graduated. That finding held across very different high schools, which is the part people usually miss when they argue that grades mean different things in different buildings. The study ran in Educational Researcher in 2020.

It makes sense when you think about what a transcript is measuring. A test measures how you perform on reading and math questions under time pressure. A transcript measures whether you turned work in, recovered from a bad quarter, handled a teacher you didn’t click with, and kept going for four years. Those are the habits that get somebody through a degree. So, when a family asks me where to spend the next six months, and there’s only room for one answer, it’s the transcript.

Does Course Rigor Matter as Much as GPA?

Close to it, and this is the piece that gets left out of nearly every version of this conversation. Rigor is its own line on a college’s published weighting, separate from GPA, and at selective schools it’s frequently rated just as high. An A in a course nobody thinks is hard does not count the same as a B in one that is. Colleges look at both your weighted and unweighted GPA, and the weighted number is mostly how they read rigor.

I bring it up because “grades matter most” is a true statement that students sometimes turn into a bad plan. If you drop out of the harder track to protect a number, you have usually traded down. What works is a strong grade in a demanding schedule, and an upward trend from freshman year on, which several large public universities look for specifically.

When Do Test Scores Matter Most?

At the most selective schools, for a reason that is more mathematical than philosophical. When nearly every admitted student already has an A average, GPA runs out of room to tell anybody apart. A study of admissions and transcript records across the Ivy-Plus colleges found that in that population test scores predicted first-year college grades about four times better than high school grades did, and that a perfect 4.0 predicted only about a tenth of a point more than a 3.2.

That finding is narrower than it sounds. It covers about a dozen of the most selective colleges, and it measures first-year grades, not graduating. It doesn’t overturn anything above. It explains why the schools with the least room to differentiate went back to requiring a score.

And they have gone back. MIT reinstated its requirement and said plainly that test scores substantially improved its ability to predict who would succeed there. Dartmouth reactivated testing after its own faculty found scores were among the most reliable indicators in its curriculum, ahead of high school GPA. Both made the same argument about access, which surprised many people: without a requirement, some well-prepared students from low-income and rural backgrounds withheld scores that would have helped them. My own daughter went from a 23 to a 27 to a 31 on the ACT, and she kept going because schools on her list brought the requirement back mid-process.

Can a Good Test Score Make Up for a Low GPA?

It can help but be precise about how. A strong score won’t replace three years of grades. What it does is offer context. If a transcript doesn’t reflect what a student is capable of, whether because of a rough sophomore year, a school change, or a stretch of something hard at home, a strong score gives an admissions officer a second data point that says the ability is there.

It runs the other way too. I have students who pull A’s in math and can’t get past a 600 on that section. Strong in one and ordinary in the other is the normal case, not a red flag. If your score is the weaker half, our post on getting into UIUC with a low SAT score shows how that conversation goes.

How Do You Decide Whether to Submit a Score?

We use the same rule for every student, and it takes about two minutes per school.

Find out whether the school requires a score. If it does, the decision is made. If it’s optional, look up the middle 50 percent range for admitted students. If the score is at the midpoint of that range or higher, send it. If it isn’t there yet and another test date is coming, wait and decide after.

It works because it uses the school’s own number rather than a guess about whether a score is “good.” A 1380 is a strong submit at one school on a list and a quiet hold at the next. Most of our students sit three or four times across junior and senior year, and because most colleges superscore, they see only the best section results. I’ve asked admissions officers about this directly and they don’t hold the extra attempts against anybody. Still deciding which test to take? Start with: should I take the SAT or ACT? Our SAT and ACT tutoring team builds the retake schedule around the deadlines.

So: protect the transcript first, take the hardest schedule you can carry without wrecking the grades in it, and plan to test anyway if there are reach schools on the list. Nine out of ten of our students earn scholarships, and a score is often part of how that happens.

Retake the test, or take the harder class?

That question comes up with almost every family we work with, and the answer depends on the student’s list, their current scores, and how much room is left in the schedule. Because our counselors and our test-prep tutors are on the same team, they work it out together instead of sending you to referee it. Book a free consultation.
