UKMDA developed the national occupational standard with the support of Construction Industry Training Board (CITB).
The qualification enables holders to obtain a Construction Skills Certification Scheme (CSCS) blue skilled worker card in metal decking and stud welding.
The first seven candidates were awarded their certificates earlier this month.
UKMDA secretary Tony Seddon said: “This is massive news for the construction industry. There’s been a huge hole in the metal decking and studwelding training sector for almost half a decade now and we are thrilled to have developed this excellent formal qualification, which sets a new standard for those working in this busy sector. It’s now up to the construction industry to get behind the NVQ, with support from UKMDA and CITB.”
