Who becomes a GCologist
Anyone who wants to improve the impact of people within teams or organisations.

How accreditation works
Two stages on Zoom, with practice in between.
-
Stage one
Complete your own GC Index profile
You answer the questionnaire and receive your own GC Index profile.
-
Attend the workshop
It lasts about five hours and takes you through The GC Index and the role of the GCologist.
-
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.
-
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.
-
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.
