Home visiting programs typically collect sensitive information about family characteristics, risk factors, and services received. States may choose to integrate these data with other early childhood data to learn more about the reach and effectiveness of the services and supports that families receive. As more states begin to integrate data across early childhood programs, data integration leaders should consider how the privacy and security of home visiting data are maintained when shared across organizations or integrated with other early childhood data. This resource describes the various types of entities, laws, and regulations that ensure the data privacy and security of home visiting data when they are used or integrated. To get data integration leaders the information they need to ensure privacy and security, we also include a series of questions for leaders to ask, research, and seek to answer prior to integrating home visiting data with other early childhood data. Data privacy means that data providers (e.g., families, home visitors, or home visiting programs) are aware of how their data will be used, shared, or reported. One component of data privacy is ensuring the security of home visiting data or safeguarding these data from being accessed by individuals or organizations that do not have permission to use or share these data.
