Major findings and conclusions: This report outlines the framework in which mode of action(s) (MOA) can be considered across life stages. The framework is based upon existing approaches adopted in the "Framework on Cumulative Risk Assessment" and identifies existing guidance, guidelines and policy papers that relate to children's health risk assessment. It emphasizes the importance of an iterative approach between hazard, dose response, and exposure analyses. In addition, it includes discussion of principles for weight of evidence consideration across life stages for the hazard characterization database.
Key science/assessment issues:This framework addresses the questions of why and how an improved children's health risk assessment will strengthen the overall risk assessment process across the Agency. This approach improves the scientific explanation of children's risk and will add value by: 1) providing for a more complete evaluation of the potential for vulnerability at different life stages, including a focus on the underlying biological events and critical developmental periods for incorporating MOA considerations; 2) evaluating of the potential for toxicity after exposure during all developmental life stages; and 3) integrating of adverse health effects and exposure information across life stages.

- Problem formulation- Focuses on the lifestage-specific nature of the analysis to include scoping and screening level questions for the analysis phase.
- Analysis- Focuses on a lifestage-specific approach to evaluating hazard, dose-response and exposure that is relevant to the scope of the problem identified in problem formulation.
- Risk characterization- Recognizes the need to consider lifestage-specific risks and explicitly describes the uncertainties and variability in the database.
