It was an absolute pleasure to do the professional coaching skills programme with Institute of Coaching Studies. It took me some time when selecting the course and I could not have made a better choice to start my path as a coach with a professional like Marion.

Taking the ICF accredited course at The Institute of Coaching Studies was a significant event in my career. By expanding my skill base outside pure therapy into coaching taught me techniques I now employ throughout my practice. Simultaneously fascinating, challenging and rewarding, I learnt all I needed and more for my application to the ICF for accreditation. Marion teaches, mentors and coaches her students in an engaging way that makes me want to pursue my coaching development with her Institute with the next level programme. I also have to say that the other people on the course were really great and I learnt a lot from them too.
I opted for both the Professional Skills Certification and Advanced Diploma and I couldn’t be happier with my experience.The small classes made it easy to connect with others in the group plus this allowed enough time to discuss the various theories, tools and foundations for a solid understanding.As for content, the included handbooks were clear, concise and organised. Other big pluses included having access to resources online and a dedicated network for other students to continue making connections, ask questions and share content beyond the course.Marion, who facilitated the classes, is incredibly knowledgeable and created a warm but engaging atmosphere where everyone is encouraged to get involved. Her insightful feedback has been invaluable for my growth as a coach.The course overall has not only blown my mind with the possibilities of coaching but it’s also been a wonderful personal journey of discovery about myself too.I would highly recommend, not only if you want to become an accredited coach, but if you want to learn more about yourself, how to connect with others and practice effective communication, as examples.I not only have the confidence to begin my career as a coach but have access to an array of tools and wonderful connections to help in my growth as a person.

I was looking for a professional coaching training and I made the right decision by choosing this one among all the other online. Marion is very knowledgeable and kind. Her teaching goes step by step to make you feel more and more confident in coaching. The coaching training (via Zoom) is a combination of learning the coaching principles and practice with others. We were in a small group which which was perfect to learn quickly, ask questions and get constructive feedback. I highly recommend! Thank you again Marion for your support and guidance throughout the course and after.

I came into the program with no previous experience and not sure what to expect. What I discovered was a very hands on and practical learning environment that gave me a great opportunity to learn all of the theory and models and put them into use in the same day. This is a great place to start or continue your coach education and training.

Brilliant Life Coaching ICF accredited course. Marion was an amazing tutor, who always had an answer to all our questions. The course was full of extremely useful information but also fun and interactive so that everyone had an opportunity to practice their coaching skills. It’s the best I could do for myself to invest in this course to start my life coaching journey with some solid foundations to build on. 5 stars for me!!!

I have thoroughly enjoyed my coaching experience with The Reflective Mind /Institute of Coaching Studies. Marion Tilly is a wonderfully patient and knowledgeable coach, her model for teaching is thorough and easy to navigate. As well as useful guidance on the ICF there are plenty of tools to study that make wonderful resources. The live sessions work particularly well as they are straight forward with structured content and offer a full explanation of how to use the tools and how ICF coaching works. I especially enjoyed working in small interactive groups learning by sharing information, asking questions and testing knowledge gained through observed coaching. I would totally recommend this course to anyone looking to up level their qualifications in this area. I'm sad to finish working together but very much looking forward to signing up for Marion's supervision services soon!

I completed my coach training with the institute recently and I’m SO incredibly pleased that I chose this program - the training is second to none. Marion, was an amazing teacher and coach who made the program an absolute pleasure to complete. I’ve actually just applied for my ICF ACC certification far sooner that I thought I’d be able to thanks to the structure and support I received from the Institute of Coaching Studies. I highly recommend to anyone who is committed to becoming the best coach they can be.


The Professional Coaching Skills Certification and the Advanced Diploma in Coaching are the two ICF-accredited programmes we deliver.

The certification is a 75-hour coach training which gives participants the keys to build a strong foundation of coaching. Participants practice coaching skills they learn in the classroom setting, as well as theories and models that can help them understand their clients better. No previous coaching experience is necessary to join the certification. It allows people to apply to the ICF ACC accreditation via the Level 1 path.

The diploma, on the other hand, is our 150-hour programme. It comprises the certification above, as well as an advanced 75-hour training which focuses on coaching psychology theories like CBT, psychodynamics and Gestalt,  as well as advanced practice and supervision. It enables participants to coach at a more advanced level. The diploma allows people to apply to the ICF ACC and PCC accreditations via the Level 2 path. To receive the diploma, you need to successfully complete both the certification and the advanced course. 

Both modules of the diploma are delivered in English.

The Advanced Diploma in Coaching is for anyone who wants to develop a solid foundation in coaching with an extensive knowledge in psychological theories and models. Even though most of our participants have prior coaching experience, you do not need to have previously coached in order to join the programme.

The Advanced Diploma in Coaching comprises two modules:

  1. Professional Coaching Skills Certification
  2. Advanced Professional Coaching Skills

Both modules are 75-hour programmes and include live classes, self-study, and individual mentor coaching.

You need to have completed the certification before the first day of advanced course.

It depends on when you register for module 2. If you want to complete both modules one after the other, it can take 6 to 8 months to complete the diploma (depending on the training dates and your commitment to complete the asynchronous part of the training).

You can skip the first module of the diploma and join module 2 directly if you already completed an ICF-accredited coach training of 60 hours minimum. We accept transfers of credit, which means you may be able to receive your Level 2 accredited diploma. For more information, please contact us by email.

If you haven’t completed an ICF-accredited training, you will need to attend module 1.

You can read more about our approach here.

Because our approach is centered on the whole person, rather than the problem clients come to coaching for, graduates of the diploma can specialise in many different areas of coaching: life, career, leadership & executive, relationships, confidence, success, well-being, business, etc.
