PSI Courses

Classes start in mid-August and run for 10 months to June of the following calendar year. Successful graduates of PSI will receive both a master's degree in physics from the University of Waterloo and a Perimeter Scholars International Certificate from the Perimeter Institute for Theoretical Physics. All courses take place at Perimeter Institute

PSI admitted its first class in the summer of 2009, graduating in 2010, and has gone on to graduate eight full classes through the 2017 period.


The coursework is divided into four phases and a short research project, the essay. The full course will advance:

  • Research Skills: problem formulation and solving, presentation skills and necessary background in numerical methods and mathematics (Four weeks, full time).
  • Core Topics: foundational subjects, such as quantum mechanics, relativity, field theory, statistical physics, dynamical systems, data analysis, and scientific computation. (Four three-week sessions, each with two courses running in parallel).
  • Reviews: subdisciplinary subjects, such as particle physics, cosmology, quantum information, quantum foundations and condensed matter physics. Students will choose from a selection of courses (Three three-week sessions, each with three courses running in parallel. Students are required to take at least four review courses in order to meet course requirements).
  • Explorations: short, in-depth courses on specialized fields which are currently "hot." Students will choose from a selection of courses (Three three-week sessions, each with three courses running in parallel. Students are required to take at least two exploration courses in order to meet course requirements).

Essay: Each student undertakes a short research project supervised by a local or outside Faculty member, and produces an essay which is publicly presented and defended.

The program also includes remedial English courses, training in scientific writing, and presentation workshops.

Although all course grades are either Credit or No Credit, PSI's approach to evaluation involves continuous assessment throughout the year conducted by PSI's resident Fellows and Faculty. The goal is to encourage all students to achieve their potential and to avoid grade-chasing competition. The final grade on the PSI Certificate will be Pass or Fail.
