An Establishment Review is equivalent to an audit. It would cover compliance with all laws and regulations (E.O. 11246, Section 503, and VEVRAA)enforced by the OFCCP. CMCEs are similar to an Establishment Review in that they cover the full scope of a contractor’s compliance as stated above, but at the corporate level. Section 503 Focused Reviews cover only those obligations in one area, i.e., Section 503 of the Rehabilitation Act of 1973. However, if other violations are found, the agency could consider expanding the investigation. The Section 503 Focused Reviews are scheduled at the headquarters of multi-establishment companies and will be conducted onsite. The other reviews (Establishment and CMCE) do not necessarily require an onsite. A Compliance Check determines whether a contractor maintains records consistent with their obligations. According to the OFCCP's website, OFCCP will not begin conducting the onsite portion of the Section 503 Focused Reviews until September 1, 2019 to allow contractors sufficient time to seek technical assistance from OFCCP’s regional and district offices.
