Talent Development Body of Knowledge (TDBoK™)

The definitive resource for the talent development profession.

The Talent Development Body of Knowledge (TDBoK™) is the first-ever, comprehensive collection of concepts, definitions, methodologies, and examples that lays the foundation and guiding principles for those who develop talent in the workplace.

The TDBoK offers a deep dive into the 23 key capability areas outlined within the Talent Development Capability ModelTM, the framework that tells talent development (TD) practitioners what they need to know and do to develop themselves, others, and their organizations. Developed by ATD, in collaboration with more than 60 subject matter experts and incorporating curated perspectives from thousands of publications, this reference guide sets the gold standard for the talent development profession.

For those preparing to obtain an ATD CI certification—the Associate Professional in Talent Development (APTD)® or the Certified Professional in Talent Development (CPTD)®—the TDBoK also serves as a resource for exam preparation.

Conveniently available in both digital and print formats, the TDBoK goes beyond training and instructional design to address the full spectrum of information TD professionals need for success—today and in the future. We recommend every TD professional have a copy on hand to learn about their field and grow their careers.
