The "Investing in Digital Skills Act" aims to significantly update the Workforce Innovation and Opportunity Act (WIOA) by formally recognizing digital skills and digital literacy as essential components of adult education and literacy objectives. This legislation explicitly adds "digital literacy skills" to the definitions within WIOA, referencing the meaning provided in the Museum and Library Services Act. The bill amends the purpose of adult education under WIOA to ensure programs assist adults in obtaining digital literacy skills necessary for employment, economic self-sufficiency, and full societal participation. It also broadens the scope of "adult education and literacy activities" to include developing and using digital technology skills and offering related activities. Furthermore, the legislation expands "family literacy services" to encompass digital literacy activities for parents and family members, while revising the definition of "literacy" to include proficiency in using digital technology for effective functioning in various societal roles.
