Creativity is a 21st-century skill that is receiving increasing attention in schools.One of the key issues that needs to be solved to facilitate the education of creativity is its’ measurement. There is however ongoing controversy on the measurement of creativity. This is an issue of debate concerning both children, adolescents’ and adults’ creativity. A growing scholarly literature, since the earliest attempts to measure creativity more than a century ago, has not yet resolved this issue. To mention just a few of questions that remain to be resolved, we can cite: 1. What is creativity? 2. Why measure it? 3. How can creativity be measured? 4. Who is the best judge of creative work? These questions will be examined in this chapter and a new tool for the evaluation of creative potential in educational settings will be described.
