No, incorrect. From my Wiki link on the US system:
"The United States au pair program offers qualified young people the opportunity to live and study in the U.S. for one or two years in exchange for providing up to 45 hours of childcare per week.[31] The au pair program was recently granted permission from the U.S. Department of State to offer a second year extension au pair program (6, 9 or 12 months), as well as a summer au pair program.
At the same time, the au pairs are required to complete an educational component of six semester hours of academic credit or its equivalent. At the end of one year, au pairs generally return to their home country, unless they and their host families choose to extend their stay for a further 6, 9, or 12 months. Alternatively, the au pair can choose to extend her period in the US with a different family. Most au pairs choose a family in a different part of the country, allowing them to have a new experience.
In the US, au pairs are provided a private bedroom, meals, remuneration tied to the minimum wage ($195.75 per week as of 24 July 2009[32]), 1 day off weekly plus a full weekend off each month, two weeks’ paid vacation, and the first $500 toward the costs of required course work to be completed at an accredited institution of higher education in order to satisfy the requirements of the educational component of the program. Au pairs are not to work more than 10 hours per day or 45 hours per week, and are not to serve as general housekeepers or assume responsibility for household management.
The US EduCare Au Pair Program is also available for families with school-age children. In this program, the au pair works a lower number of hours (not more than 10 hours a day and not more than 30 hours a week) for a weekly minimum wage of $132.64 (raised to $146.81 on 24 July 2009 in accordance with the federal minimum wage increases).[32] The family pays $1000 in educational expenses, and the au pair is required to complete 12 hours of academic credit.
Au pairs placed with families who have children under two years old must have at least 200 hours of child care experience with infants under two. Au pairs may only be placed in a family with an infant under three months old if a parent or other adult caregiver is also home and fully responsible for the infant."
Nor is there any requirement for a parent to be supervising except for the first 3 days.
" To qualify as a host family, the following requirements mandated by the State Department must be met:
A parent or other responsible adult must remain home for the first three days after the au pair’s arrival
Child must be at least three months of age, unless a parent or other responsible adult is present
There must be a written agreement between the au pair and the host family limiting hours worked to 10 hours per day and 30 hours (if in the EduCare program) or 45 hours (otherwise) per week
Au pair must be provided with a suitable private bedroom
Host family must interview the au pair by telephone or video chat prior to departure from his or her country
Host family must be U.S. citizens or legal permanent residents
Host parents must be fluent in English
Host family must pay the au pair a weekly stipend of $195.75"
" The U.S. Department of State requires that Au Pairs are:
Proficient in spoken English;
A secondary school graduate or equivalent; and
Between 18-and-26-years-old.
Capable of fully participating in the program as evidenced by the satisfactory completion of a physical.
Personally interviewed, in English, by an organizational representative who shall prepare a report of the interview which shall be provided to the host family; and
Successful in passing a background investigation that includes verification of school, three, non-family related personal and employment references, a criminal background check or its recognized equivalent and a personality profile. Such personality profile will be based upon a psychometric test designed to measure differences in characteristics among applicants against those characteristics considered most important to successfully participate in the au pair program."
