Private schools don’t inherently boost student performance

Private school demographics in the US

Private school is a costly alternative to public school. As a result, there are numerous demographic differences between public and private school attendees, typically tied to income level. This source presents the latest statistics about private school attendance, as well as a searchable database to see the differences for schools near you.

Private schools are generally smaller than public schools

As of 2021, 44% of private schools enrolled fewer than 300 students. By comparison, over 60% of public schools enroll more than 500 students.

Fewer middle-class students now attend private schools

Stanford professor Sean Reardon says there are two primary reasons behind this trend. The first is that many parochial schools, which tend to offer more affordable tuition, have closed. The second is that tuition for the remaining private schools has outpaced middle-class salaries.

Economists warn that private schools can negatively affect public schools

Lower public school enrollment often means less public school funding. Private school parents, however, frequently argue that public schools simply aren’t offering the right education for their children. This podcast episode investigates that back-and-forth in San Francisco, where 30% of children attend private schools, nearly three times the national figure.

Private K-12 schools rely on tuition; colleges rely on funding for research

Tuition, endowments, donors, and grants often fund private schools, allowing them to eschew national curriculum standards. Private colleges and universities also charge tuition, but often rely on federal funding for research.

Private schools are free to experiment with teaching styles

Because they’re not beholden to national curricula, private school teachers can use different pedagogical approaches, like Harkness, which was developed at New Hampshire’s Phillips Exeter Academy. The method brings students to a large round oval table and encourages them to lead the lesson through inquiry.

For-profit schools are not beholden to educational missions

While many private schools are nonprofit organizations, beholden to their missions and boards, some are for-profit entities owned by private individuals or corporations. In some cases, these institutions offer substandard courses and award unaccredited degrees.

School choice vouchers have had mixed results

This podcast breaks down the arguments for and against vouchers and untangles what data suggests about them. While some states showed vouchers improving student learning, studies in Louisiana and Indiana showed that students who left public schools for private schools performed worse.

Some educators argue society's obsession with colleges at the top of rankings has hurt the US higher education ecosystem

Why are "good colleges" often the ones that accept the fewest students? Speaker Cecilia Orphan argues that society's obsession with colleges that are often private, expensive, and that reject applicants with high frequency has done harm. Instead, she argues, we should focus on regional public universities that meet the needs of students in a cost-achievable manner.

After public schools were integrated, segregation found a home in private schools

The 1954 Brown v. Board of Education ruling banned segregation in public schools, but it didn’t eliminate the problem: Many white families moved to “segregation academies,” which were private schools founded to skirt the new law

One private school network prefers AI to teachers

Alpha School, a private school network that uses AI tutors and human "guides" rather than teachers, is expanding across the US. Its founder says that two hours a day with AI-powered software frees students to pursue their passions. Critics, including the Pennsylvania Department of Education, say the methods are untested.

Why donors love to give to the wealthy schools

In this podcast episode of Revisionist History, Malcolm Gladwell explores why Hank Rowan’s $100 million gift to a small New Jersey college didn’t inspire others to support underfunded schools. Instead, donors continue to flock to elite institutions like Harvard and Stanford. “My Little Hundred Million” examines ways ideology and prestige have reshaped educational giving.

Some institutional investors are growing wary of private equity, as certain investments underperform traditional market indices

Private equity often attracts investors who can afford to tie up capital for long periods of time in exchange for higher returns than traditional investments. For many years, private equity at least tracked with the S&P 500 in terms of returns to investors, but in 2024 and 2025, it underperformed and posted declining returns.

Driver education was largely removed from public schools in the 1990s

Maintaining fleets of cars proved too expensive for many school districts, relegating driver education to private classes taken outside of school.

The US lags behind other developed countries in math and science scores

The Programme for International Student Assessment, administered every three years by the OECD to 15-year-olds, scores US students below the OECD average in math (465 vs. 472) and only slightly above average in science (499 vs. 485). These figures place US pupils in the lower half of developed nations.

The pedigree of one’s MBA program matters a lot to elite employers

One expert even said that having an MBA from a prestigious school is “non-negotiable” for certain employers, such as elite management consulting, investment banking, and private equity.

The best predictor of success.

Leaving a high-flying job in consulting, Angela Lee Duckworth took a job teaching math to seventh graders in a New York public school. She quickly realized that IQ wasn’t the only thing separating successful students from those who struggled. Here, she explains her theory of “grit."

HSAs are frequently criticized for exacerbating inequality in healthcare access

Health savings accounts offer large tax advantages, but require personal contributions. Some argue that the tax advantages benefit wealthy individuals more than anyone else and that HSAs don't do much to help people who can't afford to regularly contribute to one. As a result, HSAs only decrease costs for those who can comfortably invest in them, and health inequalities between high-income and low-income individuals are exacerbated.

The belief that classical music enhances intelligence is mostly incorrect

"The Mozart Effect" was based on a 1993 study by psychologist Francis Rauscher. Rauscher played a Mozart Piano Sonata for college students and then assessed their spatial reasoning, finding it improved for 10 to 15 minutes. The media ran with a simpler story: listening to classical music made you smarter.

The Individuals with Disabilities Education Act improved the lives of many children with disabilities

Before the IDEA, many individuals lived in state institutions and received little education—only one in five attended public schools. Today, US public schools now educate over two-thirds of children with disabilities in general education classrooms.

Eggshell color doesn't indicate taste or superiority

Brown, white, and blue eggs taste and cook identically. Despite popular notions that brown eggs are superior, the shell color reflects the genetics of the hen alone. What actually determines egg quality is freshness and the diet of the hen (where grass and leafy greens lead to denser yolks). And freshness can go both ways: older eggs peel more easily than fresh ones.

Pros and cons of unions

While unions require fees and can make promoting high-performing workers and letting go of lower-performing ones more difficult in some workplaces, they have their positive aspects too. Labor unions tend to increase pay and benefits for employees, for instance.

Winning Pulitzers doesn't attract readers to newspapers

A 2014 study by Nate Silver found that newspapers that win the awards rarely see a change in circulation. While plenty has changed in the media landscape since the article was published in 2014, it's still a fascinating peek into how prestigious awards affect (or, more accurately, don't affect) readership.

School buses are the safest vehicles on the road

Even without seat belts or airbags, the big yellow school bus transporting millions of students to school each day remains the safest vehicle on the road. A long history of tragic lessons led to today's highly tested school bus design, including the padded compartments created by school bus seats, multiple emergency exits, cross-view mirrors, and more.

Polygenic scores aim to predict traits based on the contributions of many genes

These novel tests for multifactorial conditions evaluate the probability of traits like elevated blood pressure, diabetes, or high cholesterol based on what researchers currently know about different gene variants and their links to various traits. The tests are predictive, not definitive, partly because environmental factors influence the expression of genes. What's more, knowledge about cumulative effects from individual genes continues to evolve. The American Society for Reproductive Medicine states that these tests are too unreliable and nascent for clinical use.
