The Workforce Investment Act of 1998 (WIA) authorized the use of a voucher-like mechanism, called Individual Training Accounts (ITAs), by which the WIA participants can purchase training services. To ensure that customers have a selection of high-quality training providers whose training will lead to employment, states are required to provide ITA participants with a list of eligible training providers (ETP) from which ITA participants can select the provider that most meets their workforce goals. This study examines how states have designed their ETP policies and if these policies increase the quality of approved training providers as measured by the employment and training outcomes of ITA participants.
