It was reviewed and updated by ASA BOD in 2019, 2021, and most recently in 2023. In June 2020, the R. A. Fisher Award and Lectureship was changed to COPSS Distinguished Achievement Award and Lectureship. The change follows discussions about Fisher's views on race and eugenics.

ASA has more than 60 committees coordinating meetings, publications, education, careers, and special-interest topics involving statisticians. ASA is a member society of the Conference Board of the Mathematical Sciences.

As of April 2010, 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. To apply for continuing accreditation, PStat members are expected to complete 60 hours of professional development activities each year.
