As a GCologist, you show people where they have the energy to make their best impact: in a role, in a team and across a whole organisation.

Who becomes a GCologist

Anyone who wants to improve the impact of people within teams or organisations.

  • Coaches
  • Leadership consultants
  • HR practitioners
  • Management consultants
  • Team leaders and CEOs
  • Project managers
  • Board executives
  • Sports coaches

A GCologist is an accredited individual; a GC Partner is an organisation with at least one GCologist. GCologists work for a GC Partner, inside a client organisation as an in-house GCologist, or freelance.

What you can do once accredited

  • Interpret a GC Index profile and coach people to make a game-changing impact
  • Interpret team and organisation profiles, and give individuals and teams the insight in the right way
  • Use The GC Index, and the GC Partner solutions built on it, with your own clients
  • Appear in the directory of accredited GCologists
  • Join a community of GCologists who collaborate and help each other

Every GC Index profile shows how much energy a person has for each of the five proclivities.

  • StrategistMaps the future
  • Game ChangerTransforms the future
  • Play MakerOrchestrates the future
  • ImplementerBuilds the future
  • PolisherCreates a future to be proud of

How accreditation works

Two stages on Zoom, with practice in between.

  1. Stage one

    Complete your own GC Index profile

    You answer the questionnaire and receive your own GC Index profile.

  2. Attend the workshop

    It lasts about five hours and takes you through The GC Index and the role of the GCologist.

  3. Practice

    Review three people’s profiles

    You receive three practice links to send to people you choose. Once they complete the questionnaire, you review their GC Index Profile Report with each of them. Most people do this over one to three weeks.

  4. Stage two

    Attend the second session

    We arrange it once you have done your practice reviews. It lasts about two hours, and you discuss one of your review sessions with the accreditation coach and the rest of the group.

  5. Get accredited and on-boarded

    Once accredited you will have a personalised GCologist on-boarding session to understand how we can help you make your best impact as a GCologist

What GCologists say

72% of GC Partners were introduced to The GC Index by another GC Partner.

“The GC Index® profiling is a great tool to ‘have in the box’. It gives individuals a concrete basis for understanding how they work and often this can help in understanding why a person is particularly successful in one environment but not another. In particular, as a Coach, we often have a ‘feeling’ about an individual but can’t quite put our finger on that quality that is either helping or hindering them. The GC Index® helps us understand our coachees better so we can be more useful to them.”
Sammy Rashed, Principal at ScaleAbility and Co-Founder of The Beyond Group

Yes. Accreditation is required to use The GC Index and the GC Partner solutions built on it.

Is it all online?

Yes. Every accreditation course runs on Zoom, at times that suit either the UK and the Americas or the UK, Europe and Asia.
