What it's all about?

Daniel Ofman developed the Core Quadrant model in the 1990s.

With this model you can quickly gain insight into your personal Core Qualities, pitfalls, challenges and allergies (resistances).

The model is mainly used in the business world but also from Universities to Business Schools to Healthcare to almost every field where leadership and personal development are considered to be important.

We believe that the model should also be accessible to young people, which is why we wrote the book Mission9!

The use of the model is free for non commercial use only

Why it's so valuable?

People who have insight into their core quadrant are much more effective.

They are better able to align themselves with themselves and it improves the connection with others.

This allows you to make better choices for yourself, choices that fit the person you are.

It also makes communication with others much more conscious and easier.

It increases tolerance and creates appreciation for people's different qualities. With this insight you can't start early enough.

The book Mission9 is an adventurous, playful and instructive way to get started with this model.

The Book

It's 986 years into the future, and Earth has colonized 8 additional planets. Each planet created a new society based on their most valued qualities - such as on Observia where people place high importance on logic, structure and science in their everyday lives, or on Authenticum, where people value creativity, originality and beauty over all else. But, the differences in mindset between the planets grew too great, and the inhabited universe is on the verge of all-out war. Nine children - one from each planet - are sent on a journey in a last-chance effort to discover a way for the planets to find understanding and cooperation before it is too late... But will this mission succeed? Lucifix will try everything in his power to prevent a peaceful outcome. Let's just say that he has his own dark motives.... Mission9 is an engaging and easy way for children and adults alike to get started with the basic principles of understanding Core Qualities and the benefit of using the Core Quadrant system. It teaches not only that there is strength in the variety found in different types of people, but also the importance of recognizing our similarities and working through our difficulties to bring balance within ourselves and perhaps even peace !? A book that makes you look at the world in a totally different way! It will open a treasure trove of self-understanding and insight... With 29 Full-Color illustrations!

Never before has Daniel Ofman’s Core Quadrant model been explained in such a clear and exciting way.

Users of the Enneagram, will also clearly recognize the 9 Ennea types in the 9 planets!

Benefits for Education

Advantages of working with Core Educational Qualities can be:

  • Enable better study and professional choices.
  • Support pupils and teachers to get to know themselves and others much better.
  • improve communication and cooperation between colleagues, pupils and parents (greater understanding of the differences between people).
  • Prevent or stop bullying.
  • Create an environment in which naming and developing positive qualities is a matter of course.
  • Create lasting relationships, increase motivation and learning performance.
  • Prepare yourself optimally for the labour market.

Wouldn't this be great?

  • young people who are aware of their personal qualities.
  • Teachers who are able to attune themselves to their own qualities and challenges.
  • Support a new generation of young people on the road to (personal) leadership!

Shine & be Authentic!

Core Quality International

Core Quality International - Daniel Ofman

Daniel Ofman (1949) studied Business Administration at the Eindhoven University of Technology. He started his career in Philips in the field of Logistics and Material Management. His interest in new forms of management led to his going for three years to the Findhorn Foundation in Scotland, where he filled various posts, from plumber to manager (or ‘focalizer’ as it is called there) of the Business Division.

From 1980 he has been an organization developer, responsible for providing guidance to organizations in their development process. In 1984 he founded a semi-large consultancy company, Kern Konsult. After 20 years he left his company to start all over again and founded the Core Quality International organization development agency in 2004, which is currently located in The Hague, The Netherlands.

As a speaker, he is much in demand for seminars and congresses.

In 1992 his book ‘Core Qualities, a Gateway to Human Resources’ was published of which so far over 125.000 copies have been sold in the Dutch language. It has been translated in many other languages, (e.g. English and Russian).

In this first book he presented the Core Quadrant® concept, which is now widely being used in all sorts of educational institutions, from Universities to Primary Schools. In the last 25 years, over 1500 professionals (consultants, trainers and coaches) have been certified to apply his Core Quadrant® concepts both on an individual level as well as on an organizational level in mergers and restructuring processes.

He created a Core Quality Card Game, an Android/iPhone app (Core Quality) and in 2007 published You Just Wouldn’t Believe It, a case study in Philip Morris (with Guust Verpaalen, vice-president Marketing and Sales Northern Europe).

In 2008 he published Fancy Meeting Me Here…! (all about Core Qualities).

And in 2015 his latest book Building Commitment and Enthusiasm in Organisations was launched.

Three days, Train the Trainer Core Quality Programs are offered in Denmark, Norway, Sweden, Germany, Poland, Romania, France and Hungary. He travels and teaches in many countries inside and outside Europe.

Core Quality Education

Core Quality Education International - Albert Heemeijer

Our mission and vision

To support young people and adults in getting to know and make the best use of their personal Core Qualities.

Author - Trainer - Guest Speaker & Coach for Core Quadrants, Leadership and excellent Communication

Consulting partner and subsidiary of Core Quality International - Daniel Ofman

Albert Heemeijer (1967) was born in Amsterdam and studied Speech Therapy and Phonetics, specializing in the treatment of dyslexia. He managed a speech therapy practice in Germany for 10 years, beginning in 1997.

Albert has worked together with Daniel Ofman since 1999. Together they wrote the book, Mission9: the secret of the core quadrant, which was first published in Dutch and later translated to German and is now also available in English. They are also co-creators of The Great Core Quadrant Game.

Albert is responsible for giving all German-language training workshops for authorization to work with the Core Quadrant system in Germany, Austria, and Switzerland.

Leadership and communication are two of Albert’s biggest passions, both of which are central themes in this model.

Albert offers trainings, workshops, certifications and (video) coaching.

A central idea in his work is the idea that, in order to produce sustainable results, it is important that you have:

  • A good understanding of content and facts (the “it-world”, which focuses on knowledge, numbers and the analysis of information and data)
  • A good understanding of and connection with others (the “we-world”, which is about communication, making contact, and active listening)
  • A good understanding of yourself and your personal qualities, competencies and motivations (the “I-world”, which revolves around personal reflection and knowing oneself)

If one of these “worlds” is missing, then the effectiveness of a person, company and even of a country is greatly diminished.

His favorite Quote:

“Don’t ask what the world needs. Ask what makes you come alive, and go do it.

Because what the world needs, is people who have come alive.”

- Howard Thurman –
