The "Assisting In Developing Youth Employment Act" amends the Workforce Innovation and Opportunity Act (WIOA) to create new competitive grant programs aimed at providing subsidized employment opportunities for youth aged 14 through 24. The bill authorizes substantial funding, with up to $1.8 billion allocated for summer employment and up to $2.4 billion for year-round employment for each fiscal year from 2026 to 2030. These funds are intended to support planning and implementation grants for eligible entities to establish and expand youth employment programs. The legislation establishes two distinct grant programs: one for summer employment and another for year-round employment, both offering planning and implementation grants. Eligible entities include State, local, or tribal governments, as well as community-based organizations. These entities are required to form extensive partnerships with various stakeholders, including local educational agencies, workforce development agencies, child welfare services, and employers, to ensure comprehensive support for participating youth. Grant applications must detail how programs will serve eligible youth, especially those who are marginalized , and address community needs such as high unemployment or poverty. Programs must focus on developing core work readiness skills , including financial literacy, technical skills, and soft skills like communication and problem-solving. Summer employment opportunities must last at least six weeks, while year-round programs offer flexible hours tailored to in-school and out-of-school youth. A critical component of both programs is the provision of positive, supportive mentorship , with year-round programs requiring more frequent mentor contact. Grantees can use funds for wages, essential support services like childcare and transportation, and data management systems. For year-round programs, entities must also describe how they will provide mental health services and address other barriers to participation. The bill mandates specific allocations, reserving 50% of funds for in-school youth and 50% for out-of-school or unemployed youth. It also ensures regional diversity, with at least 20% of funds for rural areas and 5% for tribal areas. Priority is given to entities that coordinate with local employers, link programs to academic and occupational training, and propose plans to increase private sector engagement. To ensure accountability and effectiveness, the Secretary of Labor is required to establish performance measures for all grant recipients. These measures track outcomes such as participants' engagement in education or employment after program exit and attainment of credentials. The Secretary will conduct annual reviews and implement a system of continuous quality improvement , providing feedback and targeted support to enhance program quality.
