Physical Employment Standard (PES)
PES grades and what they mean.
Last updated 22 July 2025
The Physical Employment Standard (PES) is assigned based on your medical condition and is one of the considerations to determine your vocation during your National Service (NS) period. Should your PES change due to your medical conditions during your NS period, you may be reassigned to a different vocation or appointment accordingly.
