Legacy occupation FAQ
Is NCO 2004 the current occupation layer?
No. Current profession pages on this site are built around NCO-2015, with NCO 2004 retained as a legacy lookup signal where the source layer provides it.
Why can one old occupation code show several current pages?
Occupation titles and families may be reorganized between editions. The page keeps all current candidates instead of forcing a false one-to-one answer.
Where should I verify the occupation classification?
Use the linked NCO-2015 profession page, then check the official DGE/NCO source material for critical HR, training or compliance decisions.
