Private duty aides provide assistance in a variety of settings. They can travel to an individual's home, but they can also accompany the patient in a facility such as an assisted living or nursing home. Whether these professionals need to become licensed and bonded depends on many factors.
First, state law may mandate what criteria private duty aides must meet in order to a) call themselves by that title, and b) practice in the state. Typically, some type of license or certification is required, but the question of bonding is often determined by the aide's employer.
Most agencies require their private duty aides receive a license or certification demonstrating the appropriate training and experience for the position. In addition, bonding is common practice to reduce employee and employer liability, should the aide or patient come to harm in the course of working together.
Finally, if the private duty aide plans to work for her client in a facility, the facility might have its own rules regarding licensing and bonding. Many facilities will simply follow state law or agency protocol regarding these issues. Many times, bonding is not necessary, as the aide may be covered under the facility's bond.
