10 Great Colleges Where Your Kid Can Graduate in 4 Years or Less

A strong four-year grad rate is perhaps the single best measure of a college's quality and affordability. Not only does it demonstrate a college's ability to provide the resources and support that students need to complete their coursework in four years, but it also means that students and parents are spared a fifth or sixth year of college costs. Students can start building a career and earning money instead of paying tuition and potentially racking up more debt.

Of the 300 public and private colleges on our best values list, these 10 schools post the highest four-year graduation rates. Sharing the top honor are Carleton College and Georgetown University, both of which have a graduation rate of 91%. By comparison, the national average for both public and private schools even after six years is only 59%, according to the most recent data from the U.S. Department of Education.

Four private universities and six private liberal arts colleges make it into our top 10 list. (The University of Virginia tops all public schools, with a graduation rate of 87.4%—about two percentage points lower than the 10th school on our list, Harvey Mudd College.) Not surprisingly, these 10 schools have consistently ranked high on our best-value list, thanks in part for their high freshmen-retention rates (the lowest rate in our top 10 is 94%), low student-faculty ratios (ranging from 6 to 1 to 11 to 1) and small classes—all indicators of a supportive academic environment. For most of our top 10 schools, a high percentage of students also live on campus, forging a close-knit community where students can interact with their peers and professors. Take a look.

Founded in 1866, Carleton College is located in the historic river town of Northfield (pop. 20,000), a 45-minute drive from St. Paul and Minneapolis. Despite its small campus and small-town location, Carleton aims for its "Carls" to become well-rounded global citizens. The school's graduation requirements include proficiency in at least one foreign language, and students must take at least one class in international studies.

As with the other nine schools on our list, Carleton has a low student-faculty ratio (nine to one) and a high freshmen-retention rate (97%). The average class size is 18, and all classes are taught by faculty members rather than teaching assistants. The school offers 37 majors, and the academic year is broken into trimesters: Students take three classes during a ten-week term in the fall, winter and spring, which adds up to 12 classes each year, providing students with more opportunities to explore their interests and change majors if they choose. The school offers ample academic and financial support to both students and faculty, including a faculty-student scholarship that supports research collaborations between students and their professors.

Of the schools in our top 10, Pomona arguably has the happiest freshmen. Nearly 99% of them return to campus after freshmen year. It's easy to see why: Pomona combines the benefits of a small liberal arts college with the resources of a university. It is the founding member of the Claremont Colleges, which means the school’s 1,650 students have access to 2,500 courses and resources offered by six other colleges, including a library with 2 million volumes; a wide range of guest lectures, art performances and exhibitions; and an array of student clubs and activities. At Pomona, class size averages 15, and professors teach every class.

Pomona places a strong emphasis on undergraduate research. More than half of its students conduct research with faculty, and more than 200 students participate in research projects each summer. A total of 94% of students live on campus all four years, and many professors live within five miles of campus.

As the seven adjoining colleges grew, Claremont became a vibrant college town full of "trees and PhDs." Students can easily bump into each other and their professors at local clubs, speakers' events and the Honnold-Mudd Library, which is shared by all seven members of the Claremont College consortium.

Claremont, Calif., is an hour’s drive from Los Angeles and the mountains, desert and beaches. The location affords countless opportunities for field study, research and internships. Students can take the local commuter train or ZipCar to examine the work of Chicano muralists in L.A., climb local mountains to study deposits of volcanic rock, and learn about satellite imaging at the Jet Propulsion Laboratory near Pasadena.

This liberal arts institution places a strong emphasis on faculty-student interaction and undergraduate research. The school was founded by 13 men who each offered $13 and 13 prayers in 1819, hence the "lucky 13"—a tradition of Colgate's to celebrate Friday the 13th. With an average class size of 17 and a nine-to-one student-faculty ratio, Colgate seeks to build a residential community in which students become thoughtful and critical thinkers.

Colgate students can choose among 54 majors and numerous undergraduate research opportunities. Every summer, about 200 students receive paid summer research fellowships. These fellowships allow students to work closely with faculty for eight to 10 weeks on projects of mutual interest.

Opened right before Sputnik I launched the Space Age in September 1957, Harvey Mudd College promises a rigorous education for the nation’s brightest students in science, engineering and math with a strong underpinning of humanities and social sciences. The college charges top dollar for its education—the total cost is more than $68,000 a year (need-based aid brings the cost for those who qualify to $32,418). But the high graduation rate means that nine out of 10 students are spared the expense of a fifth or even sixth year, saving students money on the back end.

Nearly all "Mudders" live on campus, a small community neighboring Pomona College in Claremont, Calif. Like students at Pomona, Mudders have access to a large pool of resources shared by the Claremont Colleges. Students are strongly encouraged to initiate original projects and collaborate with faculty on research during the academic year and in the summer through the school’s summer research program. Harvey Mudd's Clinic program also allows students to team up and solve problems posed by sponsoring industry organizations, government agencies and nonprofit groups.
