Assessment-literacy certification training coaches to debrief the PrinciplesYou personality instrument, co-developed by Ray Dalio, Adam Grant, and Brian Little, in individual and team coaching contexts.

Understanding your own nature is the prerequisite for developing effective principles: your tendencies, your blind spots, the way you process information and make decisions. PrinciplesYou makes that understanding structured and honest, and shared across a team.
PrinciplesYou is a psychometric personality assessment co-developed by Ray Dalio (founder of Bridgewater Associates), Dr. Adam Grant (Wharton), Dr. Brian Little (Cambridge), and Dr. John Golden. It launched in 2021 as a free individual assessment grounded in the Big Five personality framework, extended with dimensions relevant to professional and organizational behavior. Participants receive an archetype designation and a detailed trait-level report used to understand how they think, communicate, make decisions, and relate to others.
