Functional Fluency

Functional Fluency is about changing the way people do things. It is about creating more effective interpersonal relationships in order to achieve what really matters, in all realms of life.

Thrive at Life!

Functional Fluency is not only a model of human social behaviour, but also a way of life. It was created by Dr. Susannah Temple who worked on developing the concept of Functional Fluency for many years in order to provide a conceptually balanced and research-based model for promoting emotional literacy.

Functional Fluency International is committed to supporting and promoting the work of the TIFF Network members and others working to spread the Functional Fluency ideas far and wide to enhance wellbeing in the world.

Transformation stories

I thoroughly enjoyed the TIFF© workshop and I have enthused about it back at home and at work. I thought it worked well, stimulating, challenging at times but encouraging and rewarding

Local Authority Manager, United Kingdom

If you want to work with behaviours with your clients, the TIFF tool has great rigour and research behind it. Clients ‘get’ the Functional Fluency model and can access its value to their development immediately. It’s visually engaging and stimulates good dialogue. The language is easy to transfer into any setting, especially the workplace. The Functional Fluency International community is also passionate and engaging.

Frequently asked questions

  • What is a TIFF©?

    The TIFF© (Temple Index of Functional Fluency) is an international award-winning coaching and personal development tool based on the Functional Fluency Model. It consists of an online questionnaire and (after completion) a one-to-one collaborative feedback session with a TIFF© Provider. The outcome is a unique, co-created profile, with discussion, support and guidance for how to put it to use. The TIFF© process puts the personal back into personal development, boosting morale, emotional literacy, self-motivation and informing behavioural change. TIFF© can help us see clearly how people behave, where they focus their energy and how effectively they do that. The self-awareness, interpersonal skills and understanding gained from TIFF© enhances people’s abilitiy to build relationships effectively and make better decisions. 

  • What makes TIFF© different from other profiling tools?

    The TIFF© feedback process involves the client exploring their personalised profile with their licensed TIFF©  provider. It is not a personality test and the feedback is not computerised. There is no typecasting or categorising of people. Through our accredited online courses – the four main Functional Fluency and TIFF© training programmes – helping professionals around the world are able to use Functional Fluency and the TIFF© personal self development tool, so they can pass on the benefits to their clients through meaningful individual encounters.


Your Personal TIFF Experience

A great way to start getting to know Functional Fluency is through your own personal "TIFF Experience". This process really puts the "personal" back into "personal development".

You can choose a licenced TIFF provider, who you feel you can connect with. This person will provide you with a link to fill in a TIFF questionnaire online in your own time. The result of this will be a snapshot of your patterns of social behaviour. In a collaborative one-on-one feeback session, your TIFF provider will support you in making sense of your behavioural profile and provide guidance for how to use this information.
