This invitational conference was convened to report the principal findings of a six-year study of possible sources of bias in the prediction of job performance. The research was conducted jointly by Educational Testing Service and the U.S. Civil Service Commission, supported by the Ford Foundation. Data were gathered on test and job performance of ethnic subgroups in three occupations in the Federal Government. The design of the study permitted a detailed analysis of the differential validity of selected aptitude tests for several kinds of performance criteria. Speakers at the conference were asked to respond to a draft of the technical report, to be published in 1973. Following an introduction to the project and a presentation of the major findings, the papers are provided. The titles and authors of the papers are as follows: "Technical Critique" by Anne Anastasi, "Implications for Employers in Government" by Raymond Jacobson, "Implications for Employers in Industry" by Lewis E. Albright, "Implications for Blacks" by Roscoe C. Brown, Jr., "Implications for Spanish Americans" by Edward J. Casavantes, "Implications for Governmental Regulatory Agencies" by Robert M. Guion, and "Implications for Future Research" by S. Rains Wallace. (Author/DB)
