The Circumplex provides a way to “see” what drives performance—that of individual contributors, leaders, and work teams—in short, the entire organization. It breaks down the factors underlying performance into 12 “styles” of thinking, behaving, and interacting. Some styles are effective and productive; some are not. Whether effective or not, they all describe what’s happening inside the organization and provide a direction for change and development.
We are committed to attaining high psychometric quality standards for our assessment instruments. These standards spring from traditionally accepted psychometric concepts regarding relevant forms of validity and reliability. We use these high standards to guide the continuous improvement process of all of our assessment instruments. These ideal standards are defined herein. Methods and validity reports are available for each product within the individual product description sections on this site.
