Caregiver assessments are crucial when evaluating the suitability and safety of individuals in a caregiving role, especially if they are not biologically or legally related to the child. These assessments are part of the broader scope of child welfare evaluations, which consider the physical, emotional, and psychological wellbeing of the child in a given environment, whether it's with relatives, foster parents, or other caregivers.
The dynamics of caregiver arrangements can vary; for example, a certain percentage of children live with foster parents, who are state-certified adults that care for children under the guidance of a relevant agency and comply with guidelines. Foster care can also include what's known as "kinship" care, where relatives such as grandparents act as foster parents.
