US News Best Colleges

Rankings are based on 17 indicators in the following areas:

• Graduation and retention – based on a school's six-year graduation rates (overall, Pell Grant students) and its first-year retention rate (overall)
• Assessment of excellence – based on a reputation survey of presidents, provosts, and deans of admission at peer institutions
• Faculty resources – based on faculty compensation, student-to-faculty ratio, and proportion of full-time faculty
• Faculty research – based on citations per publication, field weighed citation impact, publications cited in the top 5% and top 25% of journals
• Financial resources – per-student spending on instruction, research, student services and related educational expenditures
• Graduation rate performance – to calculate, US News estimates a "predicted" graduation rate, controlling for per-student spending, admission selectivity, proportion of students receiving Pell Grants, and the proportion of undergraduate degrees in STEM fields. The predicted rate is then compared to the actual rate.
• Alumni debt and earnings – based on the average federal loan debt among borrowers, as well as the proportion of federal loan recipients from the institution who were earning more than a typical high school graduate

Wall Street Journal: Best Colleges in the U.S.

The WSJ/THE College Rankings were last published in September 2021. Starting in 2023, the Wall Street Journal developed its own set of college rankings in concert with College Pulse (a firm that surveys college students) and Statista (a business intelligence platform). The WSJ debuted its new set of rankings in early September 2023, including its list of Best Colleges in the U.S.

The Best Colleges ranking are based on the following measures:

• Salary impact – a calculation that compares an institution's average alumni salary with an expected alumni salary given the institution's student population
• Years to pay off net price – a calculation that compares an institution's average net price with the boost in salary (beyond a high school graduate's salary) the alumni received from attending the institution
• Graduation rate performance – a calculation that compares an institution's graduation rate with an expected graduation rate given the institution's student population
• Student satisfaction – based on a survey of students and recent graduates that asks whether respondents would recommend their alma mater and about an institution's learning opportunities, career preparation, learning facilities, and character development
• Institutional diversity – a calculation that combines responses to a survey question about diversity with institutional data such as the proportion of Pell Grant recipients, the inclusion of students with lower family earnings, and the inclusion of students with disabilities
