Why learn with NMC
Measurement you can defend
-
Traceable to national standards
NMC maintains Cambodia's national measurement standards. Training reflects the same references our calibration work is traceable to.
-
Built around the SI
Courses are organised around the seven SI base units and the practices that keep measurements comparable across laboratories.
-
Impartially assessed
Examinations are timed and scored on the NMC server. Results are not calculated in your browser and cannot be altered from it.
-
Recognised credentials
Certificates carry a certificate number and a QR code that resolve to the official NMC registry, so an employer can confirm them independently.
How it works
From enrolment to a verifiable certificate
-
Enrol
Choose a course or examination and complete enrolment. Fees, discounts and free codes are calculated by the NMC server.
-
Learn
Work through the lessons at your own pace for the access period included with your course.
-
Sit the examination
Enter with the access code issued to you. The examination is timed and each answer is saved as you go.
-
Receive your certificate
On passing, NMC issues your certificate and records it in the public registry for verification.
Certificate verification
Confirm an NMC certificate
Employers, regulators and partner bodies can check any certificate issued by the National Metrology Center of Cambodia. Enter the certificate number exactly as printed, or scan the QR code on the document.
Privacy & security
Your records stay private
Candidate photographs and payment receipts are stored privately and are never published. Examination eligibility, fees, discounts, scores and certificate status are decided by the NMC server — not by this website.
