The SAT isn't the problem, access to prep is

Higher education remains one of the most reliable paths to social mobility, particularly for students from lower socioeconomic backgrounds. The degree itself opens doors, and so do the networks, mentors, and opportunities that come with attending a strong institution. The SAT plays a central role in determining who gets access to those institutions, which is why the debate around it matters so much.

Critics call it a wealth test. Proponents call it one of the few objective measures available. The research suggests both sides have part of the picture, and neither has the whole thing.

Here's what the data actually shows and why it matters.

What the research says about SAT scores and college success

A 2025 study from Opportunity Insights, a Harvard-based research group, examined SAT scores, high school GPAs, and college performance across multiple Ivy League and peer institutions. The findings were striking: SAT scores are four times more predictive of first-year college GPA than high school grades. Students with the highest SAT scores achieved first-year GPAs 0.43 points higher on a 4.0 scale than those with scores around 1200, and students with lower scores were five times more likely to struggle academically.

The study also found no calibration bias by income. That means a student from a low-income family who scores 1400 performs just as well in college as a student from a wealthy family who scores 1400. The test itself isn't biased in what it predicts. This finding was significant enough that it was cited by Brown, Dartmouth, Harvard, Stanford, Yale, and Caltech when they reinstated their testing requirements.

The access problem

If the SAT accurately predicts who will succeed in college regardless of background, that should be good news for students from less privileged families. And it is, for the students who take it and do well.

The problem is who doesn't take it and who doesn't score well, and why.

According to research from economists Raj Chetty, John Friedman, and David Deming at Harvard, only about a quarter of students from the bottom 20% of the income distribution even take the SAT. Of those who do, roughly 2.5% score 1300 or higher. Among students from the top 20%, about 80% take the test, and roughly one in six scores 1300 or higher. Children of the wealthiest 1% are 13 times likelier to score 1300+ than children from low-income families.

These gaps are real and they're large. As Harvard economist David Deming put it: "everything that matters in college admissions is related to wealth, including the SATs." The disparities in scores reflect a lifetime of accumulated differences in school quality, out-of-school opportunities, access to tutoring, summer programs, health, and stability. The SAT makes those differences visible. It didn't create them.

The test-optional experiment

During the pandemic, most colleges dropped their testing requirements. The rationale was straightforward: students couldn't safely take the test, so requiring it would be unfair.

What happened next was more complicated. Without test scores, admissions offices found it harder to identify academically talented students from less well-known schools. A strong GPA from an elite private school already carries context that admissions officers can evaluate, but a strong GPA from a rural or under-resourced school is harder to interpret without a standardized reference point. Several institutions that studied the results concluded that removing tests actually made it harder to identify talented students from those backgrounds.

This is why so many colleges have reversed course. Six of the eight Ivy League schools now require SAT or ACT scores, and the list of schools reinstating requirements continues to grow.

Why affordable prep matters

If test scores are this important and access to preparation is this unequal, the implication is clear: making quality test prep affordable and accessible is one of the most direct ways to expand opportunity.

Private tutoring, the gold standard for SAT preparation, costs $100 to $200 or more per hour. A full course from a major prep company can run over $1,000. These options work, but they're available primarily to families who can already afford them. The result is that the students who most need the boost from a strong SAT score are the least likely to get effective preparation.

This is the problem Sharp was built to solve. Recent advances in AI make it possible to provide the kind of adaptive, personalized instruction that used to require a private tutor, at a price point that's accessible to far more families. Sharp's mission is to empower every student to realize their academic potential, regardless of background or learning style.

Free resources like Khan Academy and College Board's practice tests have also made a real difference. The landscape is better than it was a decade ago. But there's still a gap between materials being available and having access to the structured, adaptive preparation that actually moves scores.

The SAT isn't going away, and the evidence suggests it shouldn't. What should change is how many students get the preparation that lets them show what they're capable of.
