Amherst is classified as a more selective institution by the Carnegie Foundation and is ranked first among liberal arts colleges by U.S. News and World Report, tied with rival Williams College.
During the fundraising for the project, it became clear that without larger designs, it would be impossible to raise sufficient funds. This led the committee overseeing the project to conclude that a new institution should be created. On August 18, 1818, the Amherst Academy board of trustees accepted this conclusion and began building a new college.
As early as 1815, six years before the opening of Amherst College, the question of removing Williams College to some more central part of Massachusetts was agitated among its friends and in its board of trustees. At that time Williams College had two buildings and fifty-eight students, with two professors and two tutors. The library contained fourteen hundred volumes. The funds were reduced and the income fell short of the expenditures. Many of the friends and supporters of the college were fully persuaded that it could not be sustained in its present location. The chief ground of this persuasion was the extreme difficulty of the access to it.At the same meeting of the board of trustees at which Professor Moore was elected president of Williams College, May 2 1815, Dr. Packard of Shelburne introduced the following motion: "That a committee of six persons be appointed to take into consideration the removal of the college to some other part of the Commonwealth, to make all necessary inquiries which have a bearing on the subject, and report at the next meeting." The motion was adopted, and at the next meeting of the board in September, the committee reported that "a removal of Williams College from Williamstown is inexpedient at the present time, and under existing circumstances."
But the question of removal thus raised in the board of trustees and thus negatived only "at the present time and under existing circumstances," continued to be agitated. And at a meeting on the 10th of November, 1818, influenced more or less doubtless by the action of the Franklin County Association of Congregational Ministers, and the Convention of Congregational and Presbyterian Ministers in Amherst, the board of trustees resolved that it was expedient to remove the college on certain conditions. President Moore advocated the removal, and even expressed his purpose to resign the office of president unless it could be effected, inasmuch as when he accepted the presidency he had no idea that the college was to remain at Williamstown, but was authorized to expect that it would be removed to Hampshire County. Nine out of twelve of the trustees voted for the resolutions, which were as follows:
"Resolved, that it is expedient to remove Williams College to some more central part of the State whenever sufficient funds can be obtained to defray the necessary expenses incurred and the losses sustained by removal, and to secure the prosperity of the college, and when a fair prospect shall be presented of obtaining for the institution the united support and patronage of the friends of literature and religion in the western part of the Commonwealth, and when the General Court shall give their assent to the measure."In November, 1819, the trustees of Williams College voted to petition the Legislature for permission to remove the college to Northampton. To this application, Mr. Webster says, "the trustees of Amherst Academy made no opposition and took no measures to defeat it." In February, 1820, the petition was laid before the Legislature. The committee from both houses, to whom it was referred, after a careful examination of the whole subject, reported that it was neither lawful nor expedient to remove the college, and the Legislature, taking the same view, rejected the petition. ... Thus the long and exciting discussion touching the removal of Williams College and the location of a college in some more central town of old Hampshire County at length came to an end, and the contending parties now directed all their energies to building up the institutions of their choice. (William S. Tyler, A History of Amherst College (1895))
At its opening, Amherst had forty-seven students. Fifteen of these had followed Moore from Williams College. Those fifteen represented about one-third of the whole number at Amherst, and about one-fifth of the whole number in the three classes to which they belonged in Williams College. President Moore died on June 29, 1823, and was replaced with a Williams College trustee, Heman Humphrey.
Amherst grew quickly, and for two years in the mid-1830s it was the second largest college in the United States, second only to Yale. In 1835, Amherst attempted to create a course of study parallel to the classical liberal arts education. This parallel course focused less on Greek and Latin, instead focusing on English, French, Spanish, chemistry, economics, etc. The parallel course did not take hold, however, until the next century.
Williams alumni are fond of an apocryphal story ascribing the removal of books from the Williams College library to Amherst College, but there is no contemporaneous evidence to verify the story. In 1995, Williams president Harry C. Payne declared the story false, but the legend is still nurtured by many.
Academic hoods in the United States are traditionally lined with the official colors of the school, in theory so watchers can tell where the hood wearer earned his or her degree. Amherst's hoods are purple (Williams' official color) with a white stripe or chevron, said to signify that Amherst was born of Williams.
Amherst is ranked second overall according to the fifth annual report by the National Collegiate Scouting Association which ranks colleges based on student-athlete graduation rates, academic strength, and athletic prowess.
Amherst ranked ninth in a 2004 Wall Street Journal survey of the "feeder schools" to the top fifteen business, law, and medical schools in the country.
Amherst is ranked ninth in the 2007 Washington Monthly rankings, which focus on key research outputs, the quality level and total dollar amount of scientific (natural and social sciences) grants won, number of graduates going on to earn Ph.D. degrees and certain types of public service.
According to The Princeton Review, Amherst ranks in the Top 20 among all colleges and universities in the nation as the Best Overall Academic Experience for Undergraduates, The Toughest to Get Into, Professors Get High Marks, Students Happy with Financial Aid, School Runs Like Butter, and Happiest Students.
Amherst also participates in the University and College Accountability Network (U-CAN) developed by the National Association of Independent Colleges and Universities (NAICU).
During the first year, the only course requirement mandated by the registrar is one of the roughly twenty First-Year Seminars. Each class is limited to no more than 15 students. Although topics for the seminars vary, they share a common focus on critical analysis and development of argument in writing and speaking.
The other 31 courses (usually four per semester) that must be completed in order to graduate can be elected by the individual student. Faculty advisors guide students through the process. Each faculty advisor works with no more than five first-year students to ensure a course of study that has breadth and depth and is both integrated across disciplines and intellectually fulfilling. Faculty advising continues for the remainder of each student's undergraduate career.
However, students must adhere to departmental course requirements to complete their major, including satisfactory performance on comprehensive examinations in their major field. Thirty-five percent of Amherst students in the class of 2007 were double majors. A small number triple major and many create, with faculty advice, an interdisciplinary major. Fifty percent write theses during their senior year. Those students who choose to write a senior thesis have additional faculty advisors whose areas of expertise mirror each thesis topic. Within five years of graduation, seventy-four percent of Amherst alumni attend graduate school.
Amherst places a high priority on meaningful interaction between students and their professors. Faculty are leading scholars and researchers in their fields, as well as effective teachers. The historic guiding principle is the Amherst dialogue between professor and student. Amherst classes are characterized by interchanges among students and faculty skilled at asking challenging and probing questions and offering alternative points of view. Professors are accessible and responsive to their students (both inside and outside the classroom) and build face-to-face, professor-to-student learning into the campus culture. To this end, professors serve as mentors and advisors, as well as teachers.
Traditionally, Amherst has made intensive writing for students a priority for all four years of study at all levels of instruction, throughout the curricula, and across disciplines. As a result, over the course of their undergraduate careers, students are expected to refine the form, logic, depth, and substance of their writing for a variety of audiences (in the sciences, arts, social sciences, and humanities). Amherst also has as priorities an emphasis on quantitative analysis across the disciplines and fostering global comprehension. The faculty always is striving to develop better and more innovative ways to teach and for students to learn, discover, and create. Professors find that their research often sheds new light on how they teach their classes.
Students are encouraged early to undertake independent or small group research or creative work, mentored by a faculty member, that results in an original scholarly work or other product. Professors also draw students into faculty research. In the sciences, students participate in sophisticated research, using state-of-art equipment and facilities. Students collaborate with professors and are listed regularly as co-authors on faculty articles. Students often present the findings of their work, whether self-directed or in collaboration with faculty, at regional or national conferences.
Amherst maintains a student-faculty ratio of 8:1 and has an average class size of fifteen students. The curriculum is remarkably diverse. Amherst offers 33 areas of study (with 850 courses) in the sciences, arts, humanities, mathematics and computer sciences, social sciences, foreign languages, classics, and several interdisciplinary fields (including premedical studies
), plus the possibility of creating one's own unique interdisciplinary major. A substantial number of faculty hold appointments in two departments, a traditional academic discipline and one of many interdisciplinary programs. Amherst pioneered the interdisciplinary fields of American Studies; Law, Jurisprudence and Social Thought; and Neuroscience. The American Studies department at Amherst College is the oldest department in the United States. Amherst created the interdisciplinary study of Law, Jurisprudence and Social Thought. In 1973, Amherst became the first institution to offer an undergraduate major in Neuroscience. Amherst helped pioneer many other interdisciplinary programs, including Asian languages and civilization. With such academic and professorial resourses, students and their advisors can tailor a program of study to a student's specific academic interests. As evidence of students' satisfaction with the effective teaching of Amherst professors, nearly seventy percent of alumni financially support Amherst annually through the Amherst annual fund (which supports financial aid, among other things).
Notable faculty members include, among others, modern literature and poetry critic William H. Pritchard, Beowulf translator Howell Chickering, Jewish and Latino studies scholar Ilan Stavans, novelist and legal scholar Lawrence Douglas, physicist Arthur Zajonc, Pulitzer Prize-winning Khruschev biographer William Taubman, African art specialist Rowland Abiodun, Chemist David Hansen, Natural Law expert Hadley Arkes, Mathematician Daniel Velleman, and law and society expert Austin Sarat. (See Notable alumni and faculty, below.)
Internet access is available in all student residences (one connection for each student in every room), and wireless access is available almost everywhere on campus. There are thirty-seven residence buildings, nine theme houses, and two language houses (supporting four languages). Just off campus, Amherst is caretaker and owner of the Emily Dickinson Museum in downtown Amherst, in addition to about half of the poet's manuscripts. Amherst maintains a relationship with Doshisha University in Japan, which was founded by Amherst alumnus Joseph Hardy Neesima. In accordance with the will of Amherst alumnus Henry Clay Folger, Amherst College is charged with the governance of the Folger Shakespeare Library in Washington, D.C.; Amherst maintains a close relationship with the Folger.
Off-campus, Amherst students have the opportunity to study at a number of institutions, from the National Theater Institute in Connecticut to Amherst's own Folger Shakespeare Library in Washington, D.C. The Twelve College Exchange program, of which Amherst is a member, has special exchange arrangements with Bowdoin, Connecticut, Dartmouth, Mount Holyoke, Smith, Trinity, Vassar, Wellesley, Wheaton and Williams Colleges and Wesleyan University for programs not available in the Five College area.
In the spring 2008, the College's Center for Community Engagement launched the Active Citizen Summer Program. This opportunity allows rising freshmen, sophomores, and juniors to participate in a summer internship with a local, national, or international not-for-profit organization while receiving housing, food, and transportation funding, as well as a modest salary paid by the Center for Community Engagement.
Amherst students and alumni have also received external scholarships including Fulbright scholarships, Goldwater scholarships, Rhodes scholarships and Watson fellowships.
with 64% receiving some form of financial aid. 
In July 2007, Amherst announced that scholarships will replace loans (both from the college and federal loans) in all financial aid packages beginning in the 2008-09 school year. Amherst had already been the first school to eliminate loans for low-income students, and with this announcement it joined Princeton University and Davidson College as the only colleges to completely eliminate loans from financial aid packages.
The school participates in the NCAA's Division III, the Eastern College Athletic Conference, and the New England Small College Athletic Conference (NESCAC), which includes Bates, Bowdoin, Colby, Connecticut College, Hamilton, Middlebury, Trinity, Tufts, Wesleyan, and Williams College.
Amherst is also one of the "Little Three," along with Williams and Wesleyan. This rivalry, over one hundred years old, can be considered the oldest athletic conference in the nation. A Little Three champion is informally recognized by most teams based on the head-to-head records of the three schools, but three-way competitions are held in some of the sports.
Amherst has placed in the top ten of the NACDA Director's Cup in the NCAA Division III in seven of the last ten years, including second in 2007 and 2008 . The 2007 "National Collegiate Scouting Association's Collegiate Power Ranking" ranked Amherst College second "overall", ahead of Duke, University of California, San Diego (UCSD), Notre Dame, Stanford, Northwestern, Harvard, Princeton, Yale, and MIT.
The sport of Ultimate Frisbee was started at Amherst College in the late 1960s by Jared Kass '69.
There are approximately 20,000 living alumni, of which 70 percent of make a gift to Amherst each year— the highest alumni participation rate of any college in the country.
