The New Jersey Department of Labor and Workforce Development (NJLWD) maintains a Workforce Longitudinal Data System (WLDS). For over 10 years, NJLWD has contracted with the Heldrich Center to maintain the current WLDS. In 2012, NJLWD was awarded a grant from the U.S. Department of Labor under the Workforce Data Quality Initiative (federal WDQI) to support the expansion of the WLDS. To support NJLWD and State of New Jersey efforts, the Heldrich Center is currently working with NJLWD to obtain state administrative data files for WLDS and to manage the data in WLDS to support data analyses. The Heldrich Center is using the data in WLDS to calculate performance metrics for NJLWD workforce programs, to evaluate NJLWD workforce programs, to use the data in WLDS for predictive modeling to identify which workforce services are most effective for which clients, and to calculate the post-graduate labor market outcomes of students from many of New Jersey’s two- and four-year higher education institutions.
