You don't need any particular qualifications to become a visitor assistant, although you'll usually need a good general standard of education, especially in English and maths.
There is a lot of competition for jobs and you may find some museums and galleries ask for a certain level of qualification, like A levels or equivalent.
You'll be in a stronger position when looking for work if you have:
- experience in customer care
- a knowledge of, and interest in, museums and their services
- volunteering experience in a museum or gallery
