Presents an analytical framework to assist child welfare agencies build interagency commitment to the value of training systems aimed at improving child and family service program outcomes. A training system is defined as: people (trainers, managers, and universities), resources (financial and technical), policies, and procedures. The principles, indicators, and evidence to support a mature training program are analyzed by evaluating frontline social workers/case managers, supervisors, managers, and external partners. The life cycle phases and components of training system are tracked through analysis of management/leadership, staff, resources, partnerships, and policies/procedures. Five strategies to advance a training system are: (1) evaluating system quality and effectiveness; (2) developing case practice and policy systems; (3) implementing quality assurance systems; (4) creating positive relationships between the training director and senior managers; and (5) expanding funding sources to assist training improvement plans. An assessment tool evaluates existing training systems and identifies potential areas for improvement. Case studies provide examples of effective programs.
