The purpose of this paper is to propose a new measurement method of creativity. Based on the tripartite thinking model (TTM), this paper developed the tripartite creativity test (TCT). The TCT was generated by considering creative process in problem solving. The TＣT defines creativity as the interaction of three modes of thinking: logical thinking, critical thinking, and lateral thinking. This model is apart from traditional definition of creativity that prescribes it as the skill for producing new and useful things. The TCT consists of three subtests in accordance with the tripartite model: logical thinking test, critical thinking test, and lateral thinking test. The psychometric characteristics were examined for this new measure. The reliability was examined by inter-rater agreements. The construct validity was examined by confirmatory factor analysis (CFA) and the criterion-related validity was examined by covariance structure analysis. The result showed that the TCT had sufficiently high reliability and fit the data reasonably well.
