The Hampshire College Summer Studies in Mathematics (HCSSiM) is an American residential program for mathematically talented high-school students. The program has been conducted each summer since 1971, with the exceptions of 1981 and 1996, and has more than 1,500 alumni. The program was created, and headed for many years, by David Kelly (1940–2025), a professor of mathematics at Hampshire College in Amherst, Massachusetts.

Background

The program, which was housed at Hampshire College for over 51 years, generally runs for six weeks from early July until mid-August. The program itself consists of lectures, study sessions, math workshops (general-knowledge classes), "maxi-courses" (three-week classes run by the senior staff members), and "mini-courses" (specialized shorter classes), all emphasizing collaborative mathematical exploration and discovery.

On a typical day, students spend four hours in the morning in class, have lunch together with the faculty, and then have several hours to use at their leisure. During this "down time", students and faculty members often host "quasi" lessons, where they participate in small-group activities such as juggling or making sushi. They return for the "Prime Time Theorem" (an hour-long talk on an interesting piece of mathematics given by a faculty member or a visitor), have dinner, and then spend three hours in a problem solving session. One of the instructors blogged the content of her workshop classes, including topics in combinatorics and number theory extending far beyond a typical high-school curriculum. An occasional publication has resulted from work done at the program.

Many alumni return to the campus for a few days around Yellow Pigs Day (July 17) of each year. This observance was formalized for 2006 in "Yellow Pig Math Days," which was conducted in observance of 2006 being the 34th offering of the HCSSiM Program (34 being a multiple of 17).

The Summer Studies has been funded in the past by the American Mathematical Society and the U.S. National Science Foundation.

Due to the coronavirus pandemic, the 2020 Summer Studies ran online for a shortened program of four weeks.

Despite the upcoming closure of Hampshire College, the 2026 Summer Studies was held at Hampshire's campus, and the program is expected to continue at a new campus in 2027.
