The Workforce Data Quality Initiative's Mission Statement from the United States Department of Labor's website reads:
"The long-term Workforce Data Quality Initiative and SLDS goal for States is to use their longitudinal data systems to follow individuals through school and into and through their work life."
"Enable workforce data to be matched with education data to ultimately create longitudinal data systems with individual-level information beginning with pre-kindergarten through post-secondary schooling all the way through entry and sustained participation in the workforce and employment services system."
The SLDS has been implemented nationwide in each state. It became fully operational in 2012.
