Marlboro College is an alternative liberal-arts college in Marlboro, Vermont. It was founded in 1946 by returning World War II veterans, with money received from the GI bill. The campus incorporates the buildings of an old farm that stood on the land, on Potash Hill in Marlboro, Vermont. Since then, it has grown to an eclectic group of around 330 students.

Students in their freshman year must take one or more Designated Writing Classes, and submit 20 pages of writing to the Clear Writing Committee by the end of the second semester. If the committee decides that a student's writing skills need more work, they recommend a class to help, and the student must prepare another 20 pages at the end of the next semester for re-evaluation.

During freshman and sophomore years, students are encouraged to take courses in a wide variety of subjects. For junior and senior years, students develop a Plan of Concentration, a self-designed major with a defended thesis. Much of junior and senior years are spent doing independent work and taking tutorial classes (one or two students and the instructor). The Plan culminates in a written thesis and another project that the student chooses.

The results of this work are defended in an oral examination before two Marlboro professors, and one outside evaluator who has expertise in the student's field of study but is not connected with the college. The presence of the outside evaluator ensures that the grading process is objective, rather than becoming self-referential.

Class sizes at Marlboro are small and the student-to-teacher ratio is very low. Generally one to ten students are in a class, but occasionally there are as many as thirty in a particularly popular course. Students work closely with the professors. Marlboro College has one of the highest ratings in the country, both for percentage of students to go on to graduate school, and for percentage of students who donate money to the college after graduation.
