Less than most families think. Decades of research find that a college's selectivity predicts little about how much students learn, how engaged they are at work later, or their typical earnings. What predicts a good outcome is the experience a student actually has: close professors, mentors, real projects and belonging. Those depend heavily on fit.
The assumption: harder to get into means better
Every junior year, acceptance rate quietly becomes a stand-in for quality. The search turns into a campaign to get into the most selective school possible, as if selectivity were the outcome. The research tells a different story.
What the research finds
Learning. A major review of more than 1,800 studies (Mayhew and colleagues, 2016), summarized by Challenge Success at Stanford's Graduate School of Education, found little evidence that selectivity relates to how much students learn, a pattern that has held for decades.
Earnings. Economists Stacy Dale and Alan Krueger compared students admitted to highly selective colleges who chose to attend less selective ones with classmates who enrolled at the selective school. Years later, their typical earnings were similar. The ambition and ability that got them admitted mattered more than where they enrolled. One exception: Black and Hispanic students and students from lower-income families did see higher earnings from more selective colleges.
Wellbeing and engagement at work. The Gallup-Purdue Index, a large study of college graduates, found no link between a college's selectivity and graduates' later engagement at work or overall wellbeing.
The honest nuance. A 2023 study by Raj Chetty, David Deming and John Friedman found that attending one of a small group of the most selective private colleges raised the chance of reaching the very top of a few fields, such as the top 1% of earners or leadership at elite firms, compared with flagship public universities. Typical earnings looked much the same.
What does predict a good college experience
Gallup-Purdue identified six experiences that predicted graduates' engagement at work and wellbeing years later:
- A professor who made learning exciting
- Professors who cared about you as a person
- A mentor who encouraged your goals
- A project that lasted a semester or more
- An internship that applied what you were learning
- Being actively involved in activities
Only 3% of graduates reported all six. Whether you get them depends a lot on fit: how a college's size, structure and culture match the way you learn and connect. A student who thrives on close relationships with professors may find those more easily at a smaller college with a low student-to-faculty ratio, whatever its acceptance rate.
Personality and belonging
A 2024 study of nearly 4,800 first-year students at 12 North American colleges (Stubblebine, Gopalan and Brady, PLoS ONE) found that extraversion, agreeableness and emotional stability predicted students' sense of belonging, and that the link with extraversion was a little stronger at large schools. The social setup that works well for one student at a big university can leave another feeling adrift, regardless of how selective the school is.
What this means for your college list
None of this means selective colleges aren't worth applying to. It means selectivity is the wrong thing to build a list around. A better first question is: what size, setting and style of learning would let me do my best work and feel at home? Then look for colleges, at many levels of selectivity, that offer it.
FAQ
Does it matter where you go to college? For most outcomes, including learning, wellbeing and typical earnings, research finds the experience you have matters more than the college's selectivity.
Do selective colleges lead to higher salaries? For most students, typical earnings are similar once you account for who gets admitted. The most selective colleges do appear to raise the chance of reaching the very top of a few fields, and they help some lower-income, Black and Hispanic students more.
What should I look for instead of rankings? The size, setting, teaching style and community where you're most likely to find mentors, real projects and belonging.
