What is Clean Language?
Clean Language is a simple set of questions developed by counselling psychologist David Grove. These questions are used with a person’s own words to direct their attention to some aspect of their own experience.
Asking these questions in the right context often results in an interesting new insight or the recognition of some new possibility. And if that new possibility is then questioned using Clean Language, the result can be quite profound.
"With a tool like this you can change the world."
Want to practice Clean Language skills?

You can join in our FREE peer practice sessions every Tuesday and Saturday (except in the school holidays) by joining our community site: Clean Campus, which is also a place to share ideas about all things clean. We also have a more formal practice group led by Marian Way and for which there is a small fee. You can learn about this here.
Or gain a coaching qualification?

Join us for our Clean Coach Certification Programme (Level 1 accredited programme with the ICF) to learn clean coaching methodologies to inspire capability in others and help transform their lives. Based on Clean Language and Symbolic Modelling, this is an ideal opportunity to learn these skills within the context of an ICF accredited coaching programme.
For 2026, we have both in-person (in Switzerland) and online events. The online version includes access to a private space on our Clean Campus where you can connect with the other participants between sessions for discussion, practice and extra learning.

When I think of Clean Interviewing, I think of "high fidelity." I'm convinced that if you need to relay the thoughts / knowledge / feelings / beliefs of individuals with minimal distortion, then Clean Interviewing is the best way to obtain the information. Since learning the techniques, I've started using them to facilitate communication between non-designers and designers. I've seen some evidence that "high fidelity" information from non-designers obtained early in a project can help designers to create a product that "feels right" more efficiently. I can imagine many other potential applications, and I believe that the world will be a better place if more people learn how to gather information in this respectful, non-leading way.
