I agree with maidup. In my area of work, employers take on Apprentices specifically to undertake an NVQ/Apprenticeship in the area the employer needs, and if the student meets the criteria, the qualification is fully funded. However, this lad is 19 and different criteria apply if you are 19+ - I learned last week that if an employer has previously had an Advanced Apprentice, then they have to pay an employer contribution of £900 towards other apprentices (as well as paying their basic salary, which sounds about right in this case).
In our place, the recruitment of the apprentices is joint between the employer and the training provider, to ensure that the applicants meet all the necessary criteria.
Is there an HR or training department at the place where he works? that would be my first port of call, as well as examining his employment contract to see if there is small print which says "we'll only put you forward for the qualification if you meet our minimum standards".
was he told that there would be any probationary period?
