CLSI committees conduct business at in-person meetings, four times a year called Committees Weeks. Meeting announcements and agendas are issued from the CLSI office. It is CLSI policy to conduct all meetings in an open forum and to permit noncommittee participants to attend meetings, provided proper notice has been received so that space can be reserved to accommodate attendees.
In response to the COVID-19 health care emergency, the September 2020 and January 2021 in-person meetings are now virtual.
