Advance notice is always given to NSmen to make alternative work arrangements so that they can attend ICT, as most NSmen inevitably have work commitments. Typically, 6 months' notice is given for High-Key In-Camp Training (ICT), and 3 months' notice for Low-Key ICT. Deferment applications based on Work Commitments are considered on a case by case basis, subject to the Unit's operational and manpower requirements. If there are exceptional circumstances, you may still apply for deferment via "Manage Manning & Call-Ups" module on OneNS along with any relevant supporting documents, as early as possible.
