29 CFR 1607.10 - Employment agencies and employment services.
A. Where selection procedures are devised by agency. An employment agency, including private employment agencies and State employment agencies, which agrees to a request by an employer or labor organization to device and utilize a selection procedure should follow the standards in these guidelines for determining adverse impact. If adverse impact exists the agency should comply with these guidelines. An employment agency is not relieved of its obligation herein because the user did not request such validation or has requested the use of some lesser standard of validation than is provided in these guidelines. The use of an employment agency does not relieve an employer or labor organization or other user of its responsibilities under Federal law to provide equal employment opportunity or its obligations as a user under these guidelines.
B. Where selection procedures are devised elsewhere. Where an employment agency or service is requested to administer a selection procedure which has been devised elsewhere and to make referrals pursuant to the results, the employment agency or service should maintain and have available evidence of the impact of the selection and referral procedures which it administers. If adverse impact results the agency or service should comply with these guidelines. If the agency or service seeks to comply with these guidelines by reliance upon validity studies or other data in the possession of the employer, it should obtain and have available such information.
