"I’m honoured to endorse this fascinating and refreshing evidence-based research, which is a critical component of the coaching profession. It will truly validate coaching as a more evidence-based research and the book is an essential resource guide for coaching professionals and clients. Life Is Good."

- Marshall Goldsmith

Karen Muggleton


Executive coach & human resources specialist

"The feedback I get from clients about coaching is that “it’s been of enormous value in enhancing their effectiveness.” They cite the benefit of sharing their learning and elevating their staff’s abilities. My view is that research and societal awareness is needed to shine a light on coaching that generates sustainable results for individuals, employees and employers."

Christy Whitman


Master Certified Coach &

New York Best Selling Author

"As a coach with over 20 years’ experience and someone who has been certifying coaches since 2008, I believe The Coaching Science Practitioner’s Handbook is essential reading for anyone seeking to navigate or benefit from, this rapidly expanding profession.”

Emma-Louise Elsey


Life Coach and CEO of

The Coaching Tools Company

"We know a lot about what coaching is NOT, but very little is known what coaching IS. While coaching can be experienced, it's hard to explain. Without research coaching is defined by whomever speaks loudest. This book shows that research will help define coaching, create coaching frameworks so that we can grow our coaching practice - and validate the profession of coaching."

Kerryn Griffiths


Founder of ReciproCoach

"Without research participants we have no research, and without research we have no profession. Having a significant body of credible research is essential for the field of coaching. Not every coach can complete a research project, but every coach can and should participate in research. This book combines both: practitioners’ participation and credible research."

Marcia Reynolds


PsyD, Author of 'Coach the Person Not the Problem and The Discomfort Zone'

"For knowing how coaching works we need to know how it works to teach and apply it … a rigorous evidence-based practice to become credible as a discipline. This book shares research and examines critical conversations that emerge to inspire coaches to participate in research. If you believe in coaching as a way of developing minds in this complex world, read this book!"

Maria Iliffe Wood


Executive Coach, Coach Supervisor, Author of 'Coaching Presence'

"This new world will need coaches who can facilitate transformational thinking faster than ever before….The importance and urgency for coaching research just went up by a huge leap. … With a deeper understanding of how coaching works, coaches will be in a better position to play the critical role to help people to adapt to whatever the future might bring."

Alison Lalieu


Leadership Performance Expert & Executive NeuroCoach

"The level of presence we bring to the conversation is a powerful determinant of the depth of the relationship formed throughout the engagement. Research such as this which highlights the significant role of coaching presence is vital. The book has a valuable contribution to make to our profession as coaches will learn about the benefits of developing their own coaching presence."

Reinhard Stelter, PhD


Professor of Coaching Psychology University of Copenhagen

"Tünde Erdös, Angelis Iglesias and their colleagues can - with this book - be guiding stars for us coaches and coaching psychologists concerning the further developing of our practice. We need to develop and apply integrated theories as the knowledge base for our practice and we need to strengthen the practice-based evidence of coaching. I hope that this book helps to encourage colleagues to find inspiration to improve their work by integrating theory  practice and research."

Jonathan Passmore


Professor of Coaching & Bejavioural Change, Director Henley Centre for Coaching & Behavioural Change

"Coaching practice and research are beginning to divide - with researchers fascinated by theory & practitioners … by latest tools. We need a space where practice is driven by evidence & science … by a desire to enhance outcomes.'How are you ..' argues the case for science being at the heart of practice. Now is the time for 'queens to take off their crowns and look in the mirror."

Dr Sally Bonneywell


Independent Executive Coach & Consultant, Former VP Coaching of GSK Coaching Centre of Excellence

"Tünde Erdös, Angelis Iglesias & colleagues with this book are inspirational in integrating research, theory and practice. I believe this is at the heart of sustaining excellent practice for clients and ensuring the sustainability of our industry. This book goes a long way in helping to chart the path of integration – thank you for such an excellent addition to the field."

Eric Kaufmann


Executive Coach and Facilitator, President Sagatica LLC, Author of 'Four Virtues'

"How are you, so they can be - offers deep wisdom for coaches. Wisdom is seeing below the surface and beyond the obvious. This book does that with its disciplined research and analysis. The authors don’t stop there but go on to offer insight about how coaches can evoke wisdom from clients. If you’re serious about being a catalyst for change, then heed the book’s wisdom."

Brian Underhill, PhD


Founder & CEO of CoachSource, Author of 'Mastering Executive Coaching'

"Imagine anyone understanding what a coach does as easily as they do other professions. Coaching will not advance beyond a “niche” or a “fad” without extensive scientific-based research examining and validating every aspect of our practice. This book is a call-to-action for coaches to further the scholarly advancement of the profession - and what a great call it is!"

David Clutterbuck


Professor, Special Ambassador European Mentoring and Coaching Council

"The phrase “evidence-based coaching practice” has become devalued with a flood of pseudo-research in coaching. That doesn’t mean that coaching research should be reserved for academics. Academics need to be firmly rooted in the realities of coaching practice; practitioners need to be research-literate. This volume provides the foundation for this much needed dialogue to happen."

Mark Levick


BMedScMB (Hons) PhD DipCoach FRCPA

"The future of coaching as a professional discipline will increasingly depend upon hypothesis-driven research in validating and extending the theory and practice of coaching. …This book makes a major contribution to growing coaches’ confidence in evaluating latest coaching research with the goal of informing updating and extending evidence-based coaching practice."

Krishna Kumar


Master Coach, Founder Intrad School of Executive Coaching, Past Global President International Association of Coaching

“The Coaching Science Practitioner’s Handbook makes a very timely and valuable contribution to the coaching profession that is, at this time, a relatively new one. The authenticity and deep inputs shared by experienced coaches is clearly visible as one absorbs the learning that they have shared. A must read for everyone who is actively engaged in the coaching world.”

Sanjay Modi


MBA, CEO & Founder at

“There is need for coaching to be acknowledged as a discipline in business. For that to happen coaching needs to take a scientific route of research based on both primary (experiential) and secondary data. I believe that this book is a positive step in bringing awareness around process & methodology in coaching.”

Tom Kolditz


Founding Director, Ann & John Doerr Institute for New Leaders, Rice University

"One of the challenges we have found in our coach training course is to get new coaches to fully understand coaching presence. Finally there is an evidence-based work that does a deep dive on presence and lights the way for both research on the topic, and useful outcome measurement of the effects of coaching presence."

Zsofia Juhasz


MCC, CAHRI Executive coach, mentor and supervisor, HR consultant, Past President – ICF Australasia Queensland Branch

"I find this research truly fascinating as it will offer rich insights into coaching presence. Research is important as the coaching profession evolves and matures and both coaches and buyers of coaching are interested to know more about how coaching is done – well."

Why do research?


Tünde Erdös

MSc, MCC, EMCC Senior Practitioner, PhD(c)

"In coaching, we do not want our clients to feel distressed with us. So that is why researching spontaneous responsiveness to clients’ needs struck me as essential. Non-verbal cues – the unspoken in the relationship – that occur spontaneously and effortlessly between client and coach seemed to constitute coaching presence for me. This understanding implies that coaching ..."

Right solutions meet stormy reality


Michael Tichelmann


"Looking back at my own process, I realize that I had my mind set on providing the researcher with what I thought was important: the right solutions to project-related technical issues. I was less prepared to deal with the day-to-day nuisances of running the data collection process and managing people.
In effect, we opted to start with a few selected participants to test ..."
