Adverse Impact Analysis
Validity refers to the process that establishes
evidence that supports the interpretation and use of a test score. The intent of validation studies is to
demonstrate that a test is job-related, will predict job future performance, and
is unbiased with respect to various subgroups in the population. When a test is valid, people who score high
on a test will have a higher likelihood of performing well than those who score
low.
Several methods for establishing this evidence
exist, and multiple methods are often used to build support for the use of a
test. Two of the most common methods used for selection tests are criterion-related and content-oriented
strategies. A criterion-related strategy typically establishes a statistical relationship between a test score
and a criterion measure such as job performance or training grades within a
sample of individuals. In contrast, a content-oriented strategy links the content of a test to the requirements of
the job, which are determined by a systematic job analysis. The type of strategy for establishing
validity often depends on the number of people available and the nature of the test being validated.
Evidence of validity provides a means to defend the selection test if challenged. More importantly, the validity evidence shows that an employer is hiring the right
people for the job. By increasing the number of competent employees, valid selection procedures ultimately increase the performance of the organization in which these employees work.

concerns when possible.
