Medical review
Medical review
After your medical screening, you may be given a Physical Employment Standard (PES) D. This means more information is needed before your PES can be determined. This can happen if more relevant documents and/or medical investigations are required. In the case of the latter, you may be asked to attend specialist appointments at restructured hospitals.
The actual number of medical reviews that you will be required to attend depends on the nature and complexity of your medical conditions. These medical reviews are critical and important to allow us to determine your medical fitness for full-time National Service (NS).

Letter of Identity (LOI)
An LOI waives consultation and investigative fees up to the point of diagnosis at restructured hospitals. This does not include the cost of treatment and medication that is dispensed subsequent to the diagnosis.
If you are graded PES D, we may require you to undergo further diagnosis at these hospitals and we will issue you the first LOI. For subsequent appointments, you may or may not be required to apply for additional LOIs. For changes in appointment date, you may also require a new LOI. This will depend on the type of appointment. Please refer to the above section on the medical review process for more information.
Should you require an LOI for your appointments, you must bring along the hardcopy LOI with you when you attend your appointment. If you fail to do so, you may not be allowed to attend your appointment or may have to bear the medical fees incurred for your diagnosis.
Submitting medical reports, memos or Progress Report on Medical Status
You can log in to the NS Portal and upload it under Manage Medical Matters. Alternatively, you can email it to us at contact@ns.sg or send it to the following address:
Medical Classification Centre
Central Manpower Base
3 Depot Road
#01-19
Singapore 109680
Requesting for details of your PES
Due to medical-in-confidence, we will require you to fill in the consent form before we can release the details of your PES. Please download the consent form and mail the signed form or email a scanned copy of the signed form to MCC. The details of your PES will be sent to you.
Important notes
Further Reporting Order (FRO)
An FRO will be sent to you prior to your medical appointment date. You can also log in to the NS Portal to access your FRO. The FRO specifies the medical appointment details, the required documents to bring and important instructions that you are to take note of. Attending a scheduled medical appointment is compulsory. Not complying with the FRO is an offence under the Enlistment Act. If you are unable to attend the appointment, please reschedule and update us.
Please note that any changes in appointment dates of your medical review may result in a delay in your enlistment. You should try to schedule your follow-up appointments less than two months apart if possible.
Progress Report on Medical Status (PR)
This is a form which you must pass to the attending doctor at the hospital to complete after every appointment. It is an important document for our Medical Officer to determine your medical fitness for NS. The details in the form will also help determine if you are eligible for a new LOI for your subsequent appointments (if any). You are required to submit the PR through the NS Portal after every appointment that you have attended.
Keep any forms issued to you by MCC and the hardcopy PR for a minimum of six months as you may be requested to produce them if necessary. From the conclusion of your last referral (multiple referrals may be required), we will need about three months for your final PES to be determined. This includes time for the hospital to prepare your detailed medical reports and for review by our Medical Officer.
Kindly refer to our FAQ for more information.
