The deal
How this apprenticeship works
You earn a wage from day one. You are a paid employee, not a student. There are no tuition fees - the training is funded by your employer and the government.
About 20% is “off-the-job” training. Roughly a day a week is spent learning away from your normal duties - at a college, training provider, or online - working towards a recognised qualification.
It ends with an end-point assessment (EPA). Near the end, an independent assessor checks you can do the job to the national standard - through tests, a project, a portfolio or an interview. Pass it and you are fully qualified.
How to get there
What you need to start
Level 4 (Higher) - roughly Foundation-degree level. Usually needs Level 3 (A-levels, a T-Level, or an Advanced apprenticeship) or relevant experience.
What’s next: Can lead to a Level 5/6 apprenticeship or a more senior role.
Entry requirements are set by each employer and can vary - always check the specific vacancy.
