You may choose from different au pair programs. Demi pair or summer au pair? In this case the au pair works less hours for the host family and has more time for her studies. Alternatively, you may stay as an au pair with your host family during the summer.
Demi pair (or demi au pair) is a variant of the regular au pair program. You will receive boarding and lodging as well as pocket money for child care and light housework duties. The difference is that you will only work part time as an au pair. This way you have more time for further education at a college or university. Pocket money will be less than for the regular au pair program, of course. Demi pair programs are very popular in Australia and New Zealand.
As a summer au pair you will have about the same duties as a regular au pair. The main difference is the duration of the stay abroad. You will stay as an au pair with a family for one summer. You will take care of the children during their school break and you will most likely accompany your host family during their vacation.
