It's a bit more complicated than that.
NVQ's / SVQ's are not just handed out, you have to attend training sessions run by registered training providers, submit work, be assessed in theory and practice, be assessed in the workplace and on complettion of that your work is submitted to an Awarding Board.
To be a trainer or assessor, you must complete the appropriate trainer / assessor course and if you pass you will be a qualified trainer / assessor.
We just put a dozen members of staff through an SVQ2 and it cost a shocking £900 per head. It's an absolute rip off................On the course the individual learns nothing new, assuming their employer has trained them adequately for their job, so in reality the employer has to pay out massive amounts of money to have some numpty paper check that they are doing what they've already been trained to do by their employer.
Unfortunately such " qualifications " are becoming mandatory and local authorities already require all staff and sub contracted staff to have at least the nvq 2 / svq 2
