Houston's Rice University continues to burnish its reputation in higher education.

A ranking released May 5 by QS Quacquarelli Symonds, a British company that specializes in higher education data, puts Rice at No. 23 among the top colleges and universities in the U.S. It's the highest-rated Texas school on the list.

Harvard University appears at No. 1 in the ranking, followed by Stanford University; the Massachusetts Institute of Technology (MIT); the University of California, Berkeley; and the University of California, Los Angeles (UCLA).

Elsewhere in Texas:

• The University of Texas at Austin ranks 29th.
• Texas A&M University in College Station ranks 64th.
• The University of Houston ranks 66th.
• The University of Texas at Dallas ranks 83rd.

To come up with its ranking, QS Quacquarelli Symonds looked at five factors for more than 350 colleges and universities around the country: employability, learning experience, diversity and internationalization, and research.

Here's how Rice fares in each of those categories:

• Employability, No. 42.
• Learning experience, No. 7.
• Diversity and internationalization, tied for No. 32.
• Research, No. 33.

Jack Moran, a spokesman for QS Quacquarelli Symonds, says that although the rankings "continue to command record levels of interest, we know that the American higher education sector is wrestling with questions that do not fall within the scope of our … rankings — questions of equity, access, representation, and social justice."

"The QS USA University Rankings have been carefully crafted to shine some independent light on which institutions are doing most to foster the essential relationship between education and social change," Moran adds.

More students soon will be able to take advantage of the top-rated education offered by Rice. In March, the private university announced it would expand the number of undergraduates by 20 percent by the fall of 2025. This would raise undergraduate enrollment to 4,800 and total enrollment to about 9,000.

"Rice's extraordinary applicant pool has grown dramatically despite the challenges posed by the pandemic," President David Leebron says in a news release.

Rice says the number of student applications has climbed 75 percent over the past four years. In 2020, the university received roughly 28 applications for every available slot. For the fall of 2021, almost 30,000 applicants flooded Rice, up 26 percent from the previous year.

Leebron says Rice's previous expansion of enrollment "greatly increased our national and international student applications, enrollment, and visibility. We also dramatically increased diversity on our campus, and we were able to extend the benefits of a Rice education to many more students."
