This Workshop will explore the problems and issues associated with
transporting validity in real world situations. There is little guidance from legal and
professional documents and apparently no one "right" way to conduct a
transportability study. The Workshop leader will review the information contained in
documents such as the Uniform Guidelines, the Standards for Educational and
Psychological Testing, the Principles for the Validation and Use of Personnel
Selection Procedures, relevant court cases, and relevant I-O literature.
The Workshop will then highlight issues that practitioners must
confront such as:
- Units of comparisons (e.g., tasks to tasks, KSAOs to KSAOs).
- Limits of transportability (e.g., same job to same job in different locations, similar
job to similar job, job component to job component, KSAO to KSAO).
- Circumstances requiring a transportability study (e.g., same job at a different
- Transportability in situations where the concept of job is non-existent.
- Appropriate measures of similarity.
- Degree of similarity required.
- Comparison of pros and cons for a transportability study, local validity study, validity
generalization study, no study.
- Alternatives to transportability (e.g., validity generalization, synthetic validity,
Three experienced practitioners will present examples of their work
transporting validity from one situation to another and discuss how they have answered
these kinds of questions in specific, real world situations. The Workshop will close with
a group discussion of the questions on transportability that are posed.
