The Workforce Investment Act (WIA) was a U.S. law enacted in 1998 aimed at improving the workforce development system. It provided funding for job training programs and aimed to enhance the skills of workers to meet the needs of employers. The act focused on creating a more efficient and effective workforce system by promoting collaboration among various agencies and organizations. WIA was replaced by the Workforce Innovation and Opportunity Act (WIOA) in 2014, which built upon its principles while introducing new strategies to better serve job seekers and businesses. WIOA emphasizes the importance of aligning workforce development with economic needs and improving access to training and employment services.
