This document discusses knowledge translation (KT) in child welfare. It defines KT as the exchange and application of research findings within interactions between researchers and knowledge users. The purpose of KT is to address the gap between research production and implementation in practice. It describes a researcher-on-call tool developed to facilitate KT between researchers and child welfare workers. The tool allows workers to submit questions about cases to researchers, who then search for and summarize relevant research to inform decision-making.
