Unleash the power of perspective with the ELI 360. By allowing raters of your choosing to provide feedback, you'll get a holistic understanding of how you show up in the eyes of others. The Energy Leadership® Index (ELI) assessment is the proprietary, research-backed assessment tool that takes something abstract, like the way a person views the world, and turns it into something tangible—a metric that you can see and feel and even reevaluate in the future.
