Kan. Admin. Regs. § 21-30-5 - Minimum standards for validation

(a) For the purpose of satisfying the requirements of this part, empirical evidence in support of a test's validity must be based on studies employing generally accepted procedures for determining criterion-related validity, such as those described in "standards for educational and psychological tests and manuals" published by American Psychological Association, 1200 17th Street N. W., Washington, D. C. 20036. Evidence of content or construct validity, as defined in that publication, may also be appropriate where criterion-related validity is not feasible. However, evidence for content or construct validity should be accompanied by sufficient information from job analyses to demonstrate the relevance of the content (in the case of job knowledge or proficiency tests) or the construct (in the case of trait measures). Evidence of content validity alone may be acceptable for well-developed tests that consist of suitable samples of the essential knowledge, skills or behaviors composing the job in question. The types of knowledge, skills, or behaviors contemplated here do not include those which can be acquired in a brief orientation to the job.

(b) Although any appropriate validation strategy may be used to develop such empirical evidence, the following minimum standards, as applicable, must be met in the research approach and in the presentation of results which constitute evidence of validity:

(1) Where a validity study is conducted in which tests are administered to applicants, with criterion data collected later, the sample of subjects must be representative of the normal or typical candidate group for the job or jobs in question. This further assumes that the applicant sample is representative of the minority population available for the job or jobs in question in the local labor market. Where a validity study is conducted in which tests are administered to present employees, the sample must be representative of the minority groups currently included in the applicant population. If it is not technically feasible to include minority employees in validation studies conducted on the present work force, the conduct of a validation study without minority candidates does not relieve any person of his subsequent obligation for validation when inclusion of minority candidates becomes technically feasible.

(2) Tests must be administered and scored under controlled and standardized conditions, with proper safeguards to protect the security of test scores and to insure that scores do not enter into any judgments of employee adequacy that are to be used as criterion measures. Copies of tests and test manuals, including instructions for administration, scoring, and interpretation of tests results, that are privately developed and/or are not available through normal commercial channels, must be included as a part of the validation evidence.

(3) The work behaviors or other criteria of employee adequacy which the test is intended to predict or identify must be fully described; and, additionally, in the case of rating techniques, the appraisal form(s) and instructions to the rater(s) must be included as a part of the validation evidence. Such criteria may include measures other than actual work proficiency, such as training time, supervisory ratings, regularity of attendance and tenure. Whatever criteria are used they must represent major or critical work behaviors as revealed by careful job analyses.

(4) In view of the possibility of bias inherent in subjective evaluations, supervisory rating techniques should be carefully developed, and the ratings should be closely examined for evidence of bias. In addition, minorities might obtain unfairly low performance criterion scores for reasons other than supervisors' prejudice, as, when, as new employees, they have had less opportunity to learn job skills. The general point is that all criteria need to be examined to insure freedom from factors which would unfairly depress the scores of minority groups.

(5) Differential validity. Data must be generated and results separately reported for minority and nonminority groups whenever technically feasible. Where a minority group is sufficiently large to constitute an identifiable factor in the local labor market, but validation data have not been developed and presented separately for that group, evidence of satisfactory validity based on other groups will be regarded as only provisional compliance with these guidelines pending separate validation of the test for the minority group in question. (See 21-30-9.) A test which is differentially valid may be used in groups for which it is valid but not for those in which it is not valid. In this regard, where a test is valid for two groups but one group characteristically obtains higher test scores than the other without a corresponding difference in job performance, cutoff scores must be set so as to predict the same probability of job success in both groups.

(c) In assessing the utility of a test the following considerations will be applicable:

(1) The relationship between the test and at least one relevant criterion must be statistically significant. This ordinarily means that the relationship should be sufficiently high as to have a probability of no more than 1 to 20 to have occurred by chance. However, the use of a single test as the sole selection device will be scrutinized closely when that test is valid against only one component of job performance.

(2) In addition to statistical significance, the relationship between the test and criterion should have practical significance. The magnitude of the relationship needed for practical significance or usefulness is affected by several factors, including:

(a) The larger the proportion of applicants who are hired for or placed on the job, the higher the relationship needs to be in order to be practically useful. Conversely, a relatively low relationship may prove useful when proportionately few job vacancies are available.

(b) The larger the proportion of applicants who become satisfactory employees when not selected on the basis of the test, the higher the relationship needs to be between the test and a criterion of job success for the test to be practically useful. Conversely, a relatively low relationship may prove useful when proportionately few applicants turn out to be satisfactory.

(c) The smaller the economic and human risks involved in hiring an unqualified applicant relative to the risks entailed in rejecting a qualified applicant, the greater the relationship needs to be in order to be practically useful. Conversely, a relatively low relationship may prove useful when the former risks are relatively high.
