If you would prefer to work and study at the same time, contact the training manager of a selected establishment to apply.
There are several national qualifications and learnerships available today, and employers are becoming increasingly involved in implementing these programmes for their existing staff and for new recruits. However the actual opportunities open to you in a company must be discussed with that company beforehand, as nothing is guaranteed.
Again, when approaching an employer who offers inhouse training, it is important to check that that employer is accredited to provide training.
