IMPORTANT NOTE (SAO & Harvard)

While the Center for Astrophysics (CfA) includes both the Harvard College Observatory (HCO) and the Smithsonian Astrophysical Observatory (SAO) the processes in this site are specifically for SAO personnel, unless otherwise noted. Harvard has distinct processes that should be followed for any individual with a Harvard-only affiliation. 

Some information contained on this site, such as building maps, general information about the worksite area, etc. will be useful to all incoming personnel.

Employment Terms


These categories apply only to personnel who are SAO employees, not affiliates. Affiliate/non-employee personnel would include predoctoral/postdoctoral fellows, visiting students, interns, visiting scientists, and contractors.


Personnel Role Definitions


Roles define benefits and privilege eligibility and also many factors such as pay level, pay schedule, HR processes, and more. Once a CfA Google Account is created, personnel may consult the CfA SAO Scientific Appointments Chart for the most up to date information.
