What is the difference between an Au Pair & Nanny?

Nannies are childcare providers who are paid for their expertise and experience and they are employees of the family for whom they work. Au pairs, on the other hand, are participants in a English exchange program. Au pairs provide up to 45 hours of child care per week as part of their responsibility to their host family and are considered members of the family, NOT employees. They are required to attend classes while in the UK and must return to their country after one year.
