Changes to Major Requirements
for the Classes of 2021 and 2022:

Recognizing that the 2020-2021 academic year will bring some challenges and uncertainties for Williams students, we are adapting the major requirements. For students in the Class of 2021 and Class of 2022, you may fulfill your upper level elective requirements with at least two (rather than three) courses with a laboratory component. The major still requires 9 chemistry courses, or 8 with two approved courses from biology/computer science/physics/mathematics.

See Overview in “The Major” section for a full description of the major requirements.


The Chemistry Department of Williams College provides coordinated programs of studies in all of the fundamental fields of chemistry as part of a liberal arts education. These make use of the facilities of the Thompson Chemistry Laboratory, the Morley Science Laboratories, and the South Science Building and furnish thorough preparation for graduate study in chemistry, chemical engineering, biochemistry, environmental science, medicine, and the medical sciences. The Department is accredited by the American Chemical Society.

Our courses lead students from a wide variety of secondary school science backgrounds rapidly into advanced levels, and develop a foundation and perspective for research activities and an awareness of contemporary chemistry. All members of the faculty are available to students for assistance and guidance regarding their progress and their plans for the future.
