The Oregon Office of Developmental Disability Services (ODDS) contracted with HCBS Strategies, Mission Analytics Group, and Barbara Gage of the Post-Acute Care Center for Research (PACCR) to redesign their assessment tool for individuals accessing services for intellectual and developmental disabilities (IDD). The primary goal under this effort was to update the current assessment tool to utilize nationally recognized valid and reliable items from tools including CMS’s Functional Assessment Standardized Items (FASI) tool, MnCHOICES, and the Colorado Assessment Tool. Under this effort, HCBS Strategies performed a comprehensive review of the five current tools used by the State for assessing individuals with IDD. The items within these tools were evaluated for face validity and reliability, and then cross-walked with the FASI, MnCHOICES, and the Colorado Assessment Tool to identify areas where updates were needed.
