The basic mission of all agencies is to recruit nannies and families and to match one to the other for a fee. It can be brand new or decades old, a one-person operation, or a thoroughly staffed office. In the setup of a modern nanny placement service the family, not the nanny, pays the placement fee.
Not all nanny agencies are created alike. Many trustworthy agencies have been serving clients for years, and are active in professional and trade associations. These agencies are those that truly go all-out to make the best match for your family.
If you are looking for the full time nanny in New York, then you can check various online sources.
Some are well-meaning but plainly inexperienced or lacking the resources to effectively meet your requirements. A small number are simply interested in the bottom line – move them in, move them out. Parents must be keen on choosing the agency to retain. This goes true for aspirant nannies also.
A good nanny agency saves both your time and the nannies. It should also treat both parties equally since both are clients in such a way that without one, it will not have the other. There are several things that the clients must know about the agency that they are planning to keep. These may be basic information but such will be the key to achieving both clients' goals respectively.
First, do find out how long the agency has been running. If so, know if they are a member of associations for nannies, both local and international. Also, make sure they stick to the rules and regulations of any organizations that they are affiliated with. Having known this will reassure you that its operation is not something illegal.
