Home visiting programs are designed to support pregnant women and families of children ages five and under to ensure that children are developing optimally in physical, social, and emotional domains. This study extends the literature on home visitation research outcomes by comparing two types of home visiting models: a collaborative home visiting program and a noncollaborative home visiting program. The collaborative program, called the Partnership Program, uses the resources of both the public health department and a local nonprofit organization eligible to do home visitations to deliver home visiting services. The noncollaborative program, called the Public Health Home Visiting (PHHV) Program, utilizes only the services of the local public health department. This study used panel data to assess whether children in the Partnership Program were more likely to make progress than children in the PHHV Program. Even though children in the two programs made very similar amounts of progress, children in the Partnership Program were significantly more likely to show progress in communication, gross motor, fine motor, and personal/social development than children in the PHHV Program.
