Apprenticeships are available at different levels and in a wide selection of careers. All combine working and earning a wage with studying for relevant qualifications. In England, they range from intermediate apprenticeships, which you can start at 16, up to degree apprenticeships, which require A levels and involve studying for a degree while working and having your tuition fees paid for you.

There are some fantastic opportunities with the RAF, but any interested applicants still need to pass the required selection process/medical to get in to the RAF, do initial training and then specialise in any of the above - see the information sheet below.
