The aim of this research is to develop a scale to determine university students' lifelong learning tendencies. The pre-trial form of Lifelong Tendency Scale (LLTS) containing 74 items was administered to 642 university students and explanatory factor analysis was conducted so as to determine the construct validity. On the data, items that were not significant according to the t value results were deleted from the scale and item-total correlations were also calculated. For concurrent validity, "Curiosity Index" was used and Pearson correlation coefficient having relation with the lack of curiosity sub-dimension of LLTS was found as .76. Consequently, the Cronbach alpha internal consistency coefficient of the ultimate scale containing 27 items and four sub-dimensions (motivation, perseverance, lack of regulating learning, and lack of curiosity) was calculated as .89. All the analyses conducted made it clear that LLTS was valid and reliable as a scale to determine lifelong learning tendencies.
