At the Coaching Research Institute, a research arm of COACH A, we have been conducting activities and research to visualize the state of people and organizations and to decipher the potential of coaching from a scientific perspective, based on COACH A’s many years of rich experience and research achievements in coaching for organizational development.

As one of the results of our activities, we are pleased to announce that our research paper How Can We Evaluate Coaching Sessions? Validation of the Session Evaluation Scale and Its Relationship with Coaching Effectiveness" will be presented at the Institute of Coaching’s (IOC) "Coaching in Leadership & Healthcare Conference" held in Boston on May 3-4, 2024 (EST).
We are also pleased to announce that we will be exhibiting at the conference for the third time.

Research Background and Overview

As interest in organizational coaching continues to grow and the market rapidly expands, it is important to identify and evaluate how the coaching process works in order to provide more effective coaching. However, most current evaluation methods rely on "summative evaluation," which evaluates based on results, due to the many difficulties in evaluating the coaching process.
Focusing on this issue, we have developed a Japanese version of the Coaching Session Evaluation Scale (CSES) in 2023 as a scale that enables "formative evaluation" of coaching sessions and timely evaluation of coaching sessions from the perspective of both coaches and coachees. COACH A, together with Professor Kei Fuji (Faculty of Human Sciences, University of Tsukuba) presented the results at the 87th Annual Conference of the Japanese Psychological Association held on September 15-17, 2023, as "Research on Coaching Process Evaluation Scale".
The paper that will be presented at the IOC summarizes the results of the validation of the English version of the CSES, which was developed based on the results of the earlier study.
