The Kolb Experiential Learning Profile (KELP) released in 2021, is the latest version of the original Learning Style Inventory developed by David A. Kolb. Like its predecessors, the KELP is based on experiential learning theory (Kolb 2015, Kolb & Kolb 2017) and is designed to help individuals identify the way they learn from experience. This revision includes new norms that are based on a larger, more diverse and representative sample of 26,356 users. The first chapter of the technical specifications describes the conceptual foundations of the KELP in the theory of experiential learning (ELT). Chapter 2 provides a description of the KELP that includes its purpose, history, and format. Chapter 3 describes the characteristics of the KELP normative sample. Chapter 4 includes internal reliability and test-retest reliability studies of the Learning Style inventories. Chapter 5 provides information about research on the internal and external validity for the instrument. Internal validity studies using correlation and factor analysis are reported. External validity includes research on demographics, educational specialization, concurrent validity with other experiential learning assessment instruments, aptitude test performance, academic performance, and experiential learning in teams. Chapter 6 describes the Learning Flexibility Index including scoring formulas, normative data and validity evidence.
