"with A levels how do you decide which level of apprenticeship to apply for? does it depend on whether the apprenticeship is relevant to the A levels or something else."
A levels are Level 3 so anything above that. A degree apprenticeship would be ideal as it takes them all the way through to level 6 but it may be that degree level apprenticeships don't exist for the career they want.
So, for instance if they want to be an Organ Builder, then they'd be looking at continuing at Level 3 albeit with a deep specialism
But if they want a technology / IT career then they can get a degree level apprenticeship
As is noted, it's also about what vacancies are available and whether DC is willing / able to travel/move for them. The main portion of my work is trying to find suitable employers and supporting them to put on high-quality apprenticeship programmes (so there are more vacancies for DCs to apply to). So if you work in or run a business that has scope to take on a Degree Apprentice hit me up ;-)
