DOL's General Administration Letter No. 1-00 (May 16, 2000) gives guidance on the availability of Occupational Employment Statistics Survey (OES) data and how State Workforce Agencies should use OES data in light of the American Competitiveness and Workforce Improvement Act's (ACWIA) exception to the cross-industry survey rule, for institutions of higher education, related or affiliated nonprofit entities, and nonprofit or Governmental research organizations. GAL 1-00's attachments include a set of prevailing wage policy Q&As that provide "policy and procedural guidance clarifying the intent of General Adminstration Leter (GAL) No. 2-98, particularly with regard to the use of employer-provided wage data."
