To work with children you will need the following qualifications:
You’ll usually need a qualification in
childcare like the Level 2 Certificate for the Children and Young People’s Workforce (England).
The Department for Education (DfE) has information on all approve childcare qualifications.
If you don’t have a Level 2 qualification, you can start out by working as an assistant where you’ll be supervised by more experienced staff. This could be a paid job or through volunteering. You could then train while you work.
GCSEs (A* to C) in English and maths could help you get a job.
