The increasing emphasis on government accountability at the state and federal levels has increased interest in and use of outcome data. Moreover, research has found that high performing states in integrated employment generally have a clear and visible data collection system that provides individual outcome data (Hall et al, 2007). But what are the most important elements in designing and using a system? Stakeholders have raised questions regarding creating effective data collection systems, identifying variables with the most utility for influencing policy, and using data as a strategic planning tool. This series is intended to shed light on the successes and challenges of day and employment systems across several states and to provide strategies for other states as they examine their own data collection systems and their impact on their employment priorities for individuals with intellectual and developmental disabilities (ID/DD).
