For this project, IMPAQ conducted an evaluation of the Federal Contractor Selection System (FCSS) used by the Office of Federal Contract Compliance Programs (OFCCP) of the U.S. Department of Labor. The FCSS is used by OFCCP to identify Federal contractors who do not comply with Federal laws related to employee discrimination. The goals of this project were to: evaluate the quality of the FCSS data used to identify non-compliant Federal contractors, identify employer characteristics and other factors available in the FCSS data that are strong indicators of non-compliance, evaluate the effectiveness of statistical models currently used to predict non-compliance, and suggest improvements in the OFCCP contractor selection process. To conduct this evaluation, IMPAQ reviewed the FCCS data and all documentation relevant to the data and the OFCCP selection process and conducted interviews with key OFCCP staff to assess the data collection practices, data quality, and OFCCP selection process. Using this information, IMPAQ examined the quality of the FCSS data and identified factors predictive of non-compliance of Federal contractors to develop a revised statistical model that could be used by OFCCP to predict contractor non-compliance.
