Updated on Mar 8, 2025

Pathways are a means for organizing our courses into areas. Under the 2020 requirements, undergraduates doing an AB must complete one pathway; those doing an ScB, two. Pathways were removed in the 2024 requirements. Master’s students must complete one pathway (we have not yet updated the MS requirements). The courses allowed for undergraduate pathways are somewhat different from those allowed for master’s pathways, as explained below.

For each pathway we specify core courses, graduate courses, related courses, and intermediate courses. Core courses are 1000-level courses that satisfy both undergraduate and master’s pathways. Graduate courses are 2000-level courses that may be used by undergraduates only if they’re also using a core course in the pathway. Related courses are 1000-level courses that may be used by undergraduates (but not master’s students) as part of the pathway if they’ve also used a core course. The intermediate courses are required of undergraduates completing a pathway, but are not required of master’s students.

Instructions For Undergraduates

To complete a pathway as an undergraduate, you must take one of its core courses and one other course from any of the core, graduate, and related lists. In addition, you must take the intermediate courses that are listed for the pathway. Note that it’s perfectly fine and, in fact, encouraged, for undergraduates to take 2000-level courses for which they satisfy the prerequisites. But you’re definitely not required to take any 2000-level courses.

For the intermediate courses, note that probability and statistics is satisfied only by one of CSCI 1450, APMA 1650, and APMA 1655. Linear algebra is satisfied only by one of CSCI 530, MATH 520, and MATH 540.

CSCI 1970 cannot be used as a pathway course.

Instructions For Master’s Students

To complete a pathway as a Master’s student, you must take one course that is a core course for the pathway and a second that is either a core course or a graduate course in the pathway. You don’t need to take the intermediate courses.  Taking a related course won’t count as being part of the pathway. The course you chose that is substantially different from your Pathway cannot be a course taken at another institution.

Self-Designed (for undergraduates only)

This pathway is modeled after the Brown programs for designing one’s own concentration. Students electing this pathway must write a proposal for their pathway and have it approved by an advisor and the director of undergraduate studies. The proposal must meet the breadth and overall course requirements. This must be done by the end of shopping period of the student’s seventh semester.
