9: Client Requests Validation Study
Industry: Manufacturing
Business Challenge: A large international manufacturing company had been using Resource Associate assessments for a number of years. Due to several customizations of the testing process, coupled with a recently announced business expansion, the client requested a validation study.
RA Solution: A Job Analysis was conducted by talks to Subject Matter Experts in the Human Resources Department, focus groups with supervisors who were familiar with the jobs, and by observations of work in progress in many different areas of the plant.
Next, the Personal Style Inventory and the aptitude tests were given to about 200 current employees so that we could establish a normative database for production workers. At the same time, performance ratings were collected for research purposes on all participants from the supervisor who knew them best. Then, RA ran statistical analyses to establish reliability and validity for each test and to check statistics for EEO protected groups.
Result: All aptitude tests and personality measures were judged sufficiently reliable and valid to be included in the selection test battery.
People often ask how long a selection testing validation study takes and the answer depends on several factors that mostly revolve around the sample size: difficulties with coordinating testing of the current employees, difficulties collecting performance ratings data from supervisors and / or collecting data from archival sources. Once the required data has been collected, the analysis can be done and a report prepared in about 10 business days.
