6 Griggs v. Duke Power (1971 U.S. Supreme Court) Duke Power required a high school diploma and passing score on two general aptitude tests Black applicants were disproportionately excluded Duke Power was unable to demonstrate the these requirements were job related and consistent with business necessity – Not necessary to perform most jobs in the plant Covered by Civil Rights Act, 1964

7 Selection criteria We want to select people who will succeed – Performance – Turnover – Potential How do we determine the “ right ” criteria? What should we be measuring? – Use the job analysis information to determine critical KSAOs – Knowledge/skills that are easy to learn should generally not be used as selection criteria

8 Consequences of Selection Decisions Which is worse – false positive or false negative? If false positive is worse, selection criteria should be more stringent On-the-job Performance Selection Decision True Positive False Negative False Positive True Negative

9 What is a selection test? Any device used to determine an applicant ’ s appropriateness for the job – Written tests (ability, personality, knowledge) – Interviews – Application blanks – Assessment centers All selection tests are subject to Uniform Guidelines

10 Reliability Error in a measure – Test retest (time) – Parallel forms (items) – Coefficient alpha (items) – easiest to assess – Inter-rater (raters) Reliability coefficients range from 0-1 – Acceptable is.7 or higher

11 Validity Are we measuring the right thing? – Not a characteristic of a test, but how the test is used Content validity – Based on results of thorough job analysis – Relies on judgment Criterion-related validity – Demonstrate that the test predicts performance – Uses statistical techniques Face validity – test taker perceptions of relevance

12 For next class Topic: More on selection – Benefits and drawbacks of different selection tools – Writing interview questions – Current issues in selection Will also start preparing for Interviewing Workshop on Feb 28 Exercise 2 due at the beginning of class – Must be word processed. – Be sure to explain your recommendations clearly, using the data you have analyzed.
