This document contains four papers from a symposium on evaluating the impact of human resource development (HRD). "The Politics of Program Evaluation and the Misuse of Evaluation Findings" (Hallie Preskill, Robin Lackey) discusses the status of evaluation theory, evaluation as a political activity, and the findings from a survey on the use and misuse of evaluation in HRD. "Assessing the Business Results of Management Development Using the Critical Outcome Technique at CIGNA Corporation" (Brent A. Mattson, Lawrence J. Quaranta, Richard A. Swanson) reports on a case study that detailed the utility of the critical outcome technique in evaluating a management development program at a major multiline insurance carrier and financial services company. "Investments in Intellectual Capital: Developing Methods for Measuring Impact and Value of HRD" (Laurie J. Bassi, Mark E. Van Buren) reports on a national cross-industry survey of more than 500 organizations that obtained preliminary evidence of a link between investments in human capital and organizational measures of performance (including market-to-book value). Evidence that HRD interventions focused on performance improvement deliver and 8-to-1 return on investment in 1 year or less is presented in "Demonstrating the Financial Benefit of Human Resource Development: Status and Update on the Theory and Practice" (Richard A. Swanson). (MN)
