APS Statements

APS Statements are public policy statements that undergo a meticulous process of draft and review, including receiving comments from APS members, before being voted on by APS Council at one of its semiannual meetings. The review process for APS statements may be started at anytime if deemed necessary by the Panel on Public Affairs, and at least once every 5 years.
