Measurement of the return on investment (ROI) for employee training and development has always been an important issue for researchers and executives. The American Society for Training and Development recognizes that no standard for measuring ROI has emerged, prompting it to collect case studies of measuring ROI for training and development. The study yielded 30 cases, revealing common approaches for measuring ROI. These include setting targets for each evaluation level, evaluating at the micro level, employing different methods, isolating the effects of training, effectively using sampling and converting program results to monetary values. The different evaluation methods used by the organizations that submitted case studies are follow-up assignments, surveys and questionnaires, one-on-one interviews, focus groups, observation, action planning, performance contracts, special follow-ups and performance tracking.
