Section 1606.6 - Selection procedures(a)(1) In investigating an employer's selection procedures (including those identified below) for adverse impact on the basis of national origin, the Commission will apply the Uniform Guidelines on Employee Selection Procedures (UGESP), 29 CFR part 1607 . Employers and other users of selection procedures should refer to the UGESP for guidance on matters, such as adverse impact, validation and recordkeeping requirements for national origin groups.(2) Because height or weight requirements tend to exclude individuals on the basis of national origin, the user is expected to evaluate these selection procedures for adverse impact, regardless of whether the total selection process has an adverse impact based on national origin. Therefore, height or weight requirements are identified here, as they are in the UGESP, as exceptions to the "bottom line" concept.(b) The Commission has found that the use of the following selection procedures may be discriminatory on the basis of national origin. Therefore, it will carefully investigate charges involving these selection procedures for both disparate treatment and adverse impact on the basis of national origin. However, the Commission does not consider these to be exceptions to the "bottom line" concept:(1) Fluency-in-English requirements, such as denying employment opportunities because of an individual's foreign accent, or inability to communicate well in English.(2) Training or education requirements which deny employment opportunities to an individual because of his or her foreign training or education, or which require an individual to be foreign trained or educated.
