Torrance Figural Tests of Creative Thinking (TTCT), parallel forms A and B (2008). The Figural-TTCT tests are perhaps the best-established and most used tests of creativity (Plucker, 1999) enabling comparison to other studies of creativity. The tests also offer the advantage that the scores do not penalize lack of precision. The Figural-TTCT is composed of three activities requiring 10 minutes each to complete: (a) construction of a drawing starting with an oval-shaped figure; (b) completing ten drawings on the basis of 10 incomplete figures; (c) making an original drawing on the basis of stimuli consisting of two parallel lines (form A) / circles (form B). Tests A and B were used randomly to avoid a learning effect (Torrance, Ball, & Safter 1992).
