ORNS Training Cycle

As a NSman, you will typically go through the following 3 key phases as part of your
10-year Operationally Ready National Service (ORNS) training cycle:

During this period, you may be called up for up to 40 days of ORNS activities annually.

Key ORNS Activities

As part of your ORNS training cycle, you must fulfil the following requirements:




Participate in ICT


In a work-year , you may be called up for:

  • High Key (HK) ICT, which lasts at least 7 consecutive days
  • Low Key (LK) ICT, which lasts 6 days or less


You will be notified of your ICT via SAF100 , which you are required to acknowledge. If you are unable to attend, you must apply for deferment.


Your SAF100 will also instruct you on your reporting attire. Please visit the SAF eMarts if you need to replace and replenish your personal equipment.

Placed on Manning

You will be placed on Manning to maintain your operational readiness. During these periods, you must be ready at any time to report to your Mobilisation Centre upon activation. You will be notified by phone and codewords representing your unit broadcast through mass media like TV and radio.

Pass Your IPPT

You must book and pass your 3-station IPPT within your annual IPPT Window .

You can also take 10 sessions of IPPT Preparatory Training (IPT) to fulfil your IPPT requirements instead.

You must take up to 20 sessions of Remedial Training (RT) in your next IPPT Window if you:

  • Fail or did not attempt your IPPT
  • Do not complete your IPT


Throughout your ORNS training cycle, it is your responsibility to:

Keep your personal particulars on the NS Portal updated so that you remain contactable by MINDEF for your national duty

Apply for an Exit Permit (EP) if you are travelling overseas for 6 months or longer

Inform your employer of your call-ups so that arrangements can be made to cover your duties

These include the NS HOME (National Service HOusing, Medical and Education) Awards, annual tax relief, National Service Excellence Award (NSEA), and the NS Gift Watch.

Completion of ORNS

Your ORNS training cycle will be completed after you have achieved 10 active ORNS years and 7 High-Key ICT. Thereafter, you will be phased into the MINDEF Reserve (MR).

However, you will still need to apply for an EP if you are travelling overseas for 6 months or longer. You may also be activated for operational service up to your statutory age .
