COVID-19 has left tens of millions of Americans out of work or uncertain about the future of their current jobs, and thousands of firms urgently reassessing their own viability and path forward. Even before the pandemic led to the highest national unemployment rate since the Great Depression, American businesses and workers were anxious about how emerging technologies could potentially change which skills are in demand, and challenge workers to navigate careers requiring continual learning and adaptation. Both public policy and private sector leaders must prioritize support for building a US workforce with the necessary skills to outmaneuver this disruption. Public- and private-sector leaders must respond and provide immediate training and upskilling opportunities for dislocated and economically vulnerable workers. They must also devise a comprehensive, collaborative longer-term strategy for training the US workforce through partnerships between public- and private-sector actors, including academia, to meet employers' needs and ensure that workers can secure good jobs that are in demand, with prospects for continuing training and advancement, enabling them to contribute to and share in recovery and growing prosperity in the years ahead. This report explains the challenges to training and upskilling the US workforce even prior to COVID-19, and how COVID-19 has increased the need for these programs. It then presents a US job training system capable of meeting the challenges of a post-COVID-19 economy. Specifically, this report recommends the following near- and longer-term actions to achieve workers' goals and build a modern, highly skilled workforce: (1) Tuition support for workers; (2) Grants to strengthen instructional quality and capacity at community colleges; (3) Incentivizing employers to upskill their employees; (4) Public-private collaboration to align new job skills with training programs; (5) An information ecosystem; and (6) Support for the most effective training models .
