This article updates information about the Torrance Tests of Creative Thinking (TTCT) by reporting on predictive validity data from the most recent data collection point in Torrance's longitudinal studies. First, we outline the background of the tests and changes in scoring over the years. Then, we detail the results of the analyses of the 40-year follow-up on the TTCT resulting in a structural equation model, which demonstrates the validity of the TTCT for predicting creative achievement 40 years after its administration. Finally, we provide a rationale for the relevance of the test in schools today.
