The Creativity Wheel is a truly wonderful resource to help evaluate creativity from Creative Partnerships developed by Caroline Redmond in 2004 The Creativity Wheel is a well established resource that has now been used by many schools to assist in the creativity process, by helping teachers in tailoring their teaching towards pupil improvement, involvement and motivation, in addition to enabling individual, class and whole school self assessment of creativity and creative learning.
There are a png and word doc versions of the wheel that can be downloaded and supporting teacher resource on assessing creative development.
The UK government stopped funding Creative Partnerships in 2011. Tragic shortsightedness. We desperately need politicians with integrity and vision.
