Use of other validity studies.
A. Validity studies not conducted by the user. Users may, under certain circumstances, support the use of selection procedures by validity studies conducted by other users or conducted by test publishers or distributors and described in test manuals. While publishers of selection procedures have a professional obligation to provide evidence of validity which meets generally accepted professional standards (see section 5C of this part ), users are cautioned that they are responsible for compliance with these guidelines. Accordingly, users seeking to obtain selection procedures from publishers and distributors should be careful to determine that, in the event the user becomes subject to the validity requirements of these guidelines, the necessary information to support validity has been determined and will be made available to the user.
B. Use of criterion-related validity evidence from other sources. Criterion-related validity studies conducted by one test user, or described in test manuals and the professional literature, will be considered acceptable for use by another user when the following requirements are met:
(1) Validity evidence.
Evidence from the available studies meeting the standards of section 14B of this part clearly demonstrates that the selection procedure is valid;
(2) Job similarity.
The incumbents in the user's job and the incumbents in the job or group of jobs on which the validity study was conducted perform substantially the same major work behaviors, as shown by appropriate job analyses both on the job or group of jobs on which the validity study was performed and on the job for which the selection procedure is to be used; and
(3) Fairness evidence.
The studies include a study of test fairness for each race, sex, and ethnic group which constitutes a significant factor in the borrowing user's relevant labor market for the job or jobs in question. If the studies under consideration satisfy paragraphs (1) and (2) of this section but do not contain an investigation of test fairness, and it is not technically feasible for the borrowing user to conduct an internal study of test fairness, the borrowing user may utilize the study until studies conducted elsewhere meeting the requirements of these guidelines show test unfairness, or until such time as it becomes technically feasible to conduct an internal study of test fairness and the results of that study can be acted upon. Users obtaining selection procedures from publishers should consider, as one factor in the decision to purchase a particular selection procedure, the availability of evidence concerning test fairness.
C. Validity evidence from multiunit study. if validity evidence from a study covering more than one unit within an organization statisfies the requirements of section 14B of this part, evidence of validity specific to each unit will not be required unless there are variables which are likely to affect validity significantly.
D. Other significant variables. If there are variables in the other studies which are likely to affect validity significantly, the user may not rely upon such studies, but will be expected either to conduct an internal validity study or to comply with section 6 of this part.
