Life and career skills are essential attributes for living in the 21st century because they are important to both learning and working in local and international workplaces. This study tried to create a measurement model of life and career skills and develop an online scale for investigating the psychometric property of the scale. The participants consisted of 646 primary students in Northern, Central, Southern and North eastern regions of Thailand. Then, the classical test theory, the multidimensional item response theory and the confirmatory factor analysis (CFA) were used for data analysis. The analysis of data appeared as item of difficulty index, discrimination power index and reliability of the scale. In addition, the multidimensional analysis and the CFA of data showed item fit and construct validity of the scale. This may lead to the development of clear and correct measure of students’ life and career skills structure. Policy implications are discussed.
