No,
It just means you have to be competent in the job. Competence is inferred or proved by the length of time you spent in the job (the criteria is laid down in the standards for each particular NVQ) or qualifications gained whilst doing the job.
The awarding body has to be satisfied as to your occupational competence so what happens is your CV is sent to the EV for him/her to check, obviously your CPD would play a big part as well.
Hope that clarifies the situation.
