Over the past four decades, research has identified "vertical development" as a critical aspect of how adults learn, grow and mature. This evidence-based work has major implications for the ongoing personal and professional journey towards greater maturity for our clients and ourselves.  We will share an overview of what we mean by vertical development, how we measure it, and how coaches can use this perspective — and assessment tools — to support individuals and organizations in their growth. The Maturity Profile is regarded as the most reliable stage-measure assessment of adult development. In this highly interactive webinar, we offer a practical approach to coaching for vertical development based on sound theory and application. Coaches get a sense of the value of adding this lens and capability to their repertoire. We also examine how the VeDA approach is distinguished from other developmental models and instruments in the field.
