What type of document provides specific answers to questions about practice?

The correct choice is a document that falls under the category of "interpretation." These documents are essential as they offer detailed insights and explanations regarding various practices, procedures, and guidelines in child welfare. Interpretations serve to clarify policies or regulations, providing specific answers to often complex questions practitioners may have about their application in real-world scenarios.

In the context of child welfare, interpretations help ensure that staff understand and implement practices consistently and effectively. They bridge the gap between broad policy and practical application, allowing for tailored guidance that addresses the nuances involved in casework.

Policy documents, while essential for outlining organizational standards and expectations, do not typically delve into specific application scenarios. Service goals focus more on the objectives of programs rather than the procedural clarifications needed in practice. Reports present findings or data often post-factum but do not generally provide interpretative guidance. In contrast, interpretations are designed to help practitioners navigate the intricacies of their work, making them critical in the field of child welfare.
