As home visitation programs go to scale, numerous challenges are faced in implementation and quality assurance. This article describes the origins and implementation of Every Child Succeeds, a multisite home visitation program in southwestern Ohio and Northern Kentucky. In order to optimize quality assurance and generate new learning for the field, a Web-based system (eECS) was designed to systematically collect and use data. Continuous quality assurance procedures derived from business and industry have been established. Findings from data collection have documented outcomes, and have identified clinical needs that potentially undermine the impact of home visitation. An augmented module approach has been used to address these needs, and a program to treat maternal depression is described as an example of this approach. Challenges encountered are also discussed.
