Automation and advanced technologies have increased the need for a better understanding of the skills necessary to have a globally competitive workforce. This study used data from the Program for the International Assessment of Adult Competencies to compare problem-solving skills in technology-rich environments among adults in South Korea, Germany, Singapore, Japan, Canada, Estonia, the United Kingdom, the United States, and Australia. Overall, the United States had the lowest scores among all countries, and in all countries scores declined with age. The United States had higher proportions of survey participants in the lowest skill category and lower proportions in the top-skill categories. The results of this study suggest changes in the U.S. educational and lifelong learning systems, and policies may be necessary to ensure all adults have the necessary skills in a competitive workforce.
