The Investing in Digital Skills Act amends federal workforce development law to recognize digital literacy and information literacy as essential components of adult education and job training programs. The legislation expands the definition of adult education to explicitly include digital skills training, such as using technology to find information, evaluate content, and use digital tools effectively in the workplace and daily life. The bill affects adults participating in workforce development and adult education programs funded under the Workforce Innovation and Opportunity Act, as well as program administrators who will need to incorporate digital literacy into their curricula. While the bill does not specify new funding amounts or timelines, it requires that existing workforce development resources be directed toward these digital skills objectives alongside traditional literacy and employment training.
