New Fellowships of the ASA are granted annually by the ASA Committee on Fellows. Candidates must have been members for the preceding three years but may be nominated by anyone. The maximum number of recipients each year is one-third of one percent of the ASA membership.
ASA is organized in Sections, Chapters and Committees. Chapters are arranged geographically, representing 78 areas across the US and Canada. Sections are subject-area and industry-area interest groups covering 22 sub-disciplines. ASA has more than 60 committees coordinating meetings, publications, education, careers, and special-interest topics involving statisticians.
As of April 2010[update], the ASA offers the Accredited Professional Statistician status (PStat), to members who meet the ASA's credentialing requirements, which include an advanced degree in statistics or related quantitative field, five years of documented experience, and evidence of professional competence. A list of current members with PStat status is available.
