The process of formally admitting a client into a specific program or service offered by an organization. During the enrollment process, the client’s information is captured and recorded in the HMIS software system, and they are assigned to a program or service. This information includes client demographics, service history, case notes, and other relevant data. The enrollment process is important because it allows organizations to track the progress of a client in a particular program or service, and it helps them to make informed decisions about resource allocation and service delivery.
