The International Award Committee (IAC), each panel with a three-award-year term, meets each October to consider both the full list of nominees and its shortlist submitted by the SAC. Aiming for unanimous decisions in each case, the award committee gradually finalises the nominations for awardees in medicine and public health for scrutiny by the Board of Trustees of the Prince Mahidol Award Foundation. The committee members lists strong areas of achievement and potential high achievers to be recommended to the SAC for further research.
The IAC comprises both Thai and foreign members who are renowned scientists and public health workers, some of whom are Nobel laureates, World Food Prize recipients and Magsaysay Awardees.
