Singapore's 50-year-old NS medical classification system overhauled; new health grading from Oct 2027
Singapore's Physical Employment Status (PES) system — used for NS medical classification for over 50 years — will be replaced by a new health grading framework from October 2027. Enlistees will receive specific medical exemptions tied to their conditions rather than a single PES grade, allowing more precise vocation matching. SAF conducted pilot tests in basic military training centres in 2023-2024; commanders expressed confidence in training safely under the new framework. Separately, Chan Chun Sing noted that three out of four PES appeal cases historically sought upgrades, reflecting enlistees' desire for more demanding vocations.
