This exploratory study will examine the individual, program, and agency factors that impact home visitor ability to engage parents. The study has three primary goals: 1) to understand the push-pull between standardization and individualization as it takes place in EHS home visiting programs; 2) to understand how home visitors develop the ability to achieve engagement; and 3) to integrate the findings from goal one and goal two to understand how implementation choices made by individual programs impact home visitor ability and experience in engaging parents. This is a comparative case study, with the primary form of data collection being 30-minute phone interviews with EHS program managers or directors. Findings will inform replicable models of approaches to team building, mentoring, supervision, and training that could be implemented across the spectrum of possible program design in EHS.
