The Office of Federal Contractor Compliance Programs (OFCCP) requires federal contractors to “identify the gender, race, and ethnicity of each employee” (41 CFR 60-1.12(c)). To clarify the regulations, OFCCP developed a Frequently Asked Question (FAQ) on the topic: What is the correct procedure for a contractor to obtain the ethnic information of its employees and applicants? OFCCP regulations 41 CFR 60-1.12(c) indicate that for any personnel or employment record a contractor maintains, it must be able to identify the gender, race, and ethnicity of each employee and, where possible, the gender, race and ethnicity of each applicant. OFCCP has not mandated a particular method of collecting the information. Self-identification is the most reliable method and preferred method for compiling information about a person's gender, race and ethnicity. Contractors are strongly encouraged to rely on employee self-identification to obtain this information. Visual observation is an acceptable method for identifying demographic data, although it may not be reliable in every instance. If self-identification is not feasible, post-employment records or visual observation may be used to obtain this information. Contractors should not guess or assume the gender, race or ethnicity of an applicant or employee.
