The GSA student affairs community is open to faculty and professional staff working in student support, well-being, career advising, and transition to residency. The work of the GSA student affairs community is led by the Committee on Student Affairs (COSA).
Access Resources on Student Affairs
COSA and career advising; the health and well-being of medical students; the ethical and professional development of students; academic support and resources, and the preparation of students for the transition from medical school to residency.
COSA Committee Charge
The committee discusses issues of national interest that are brought to its attention by GSA constituents, inclusive of students, and AAMC staff. The committee may identify projects, where an issue is of national importance and interest. The committee is advisory to the GSA Steering Committee and, as such, makes regular reports to the steering committee and seeks approval of the steering committee for special projects.
