Work Sampling and Performance Simulation Tests Work sampling and performance simulation tests create a miniature replica of a job. These tests require the applicant to demonstrate specific competencies that have been identified as necessary for performing the job successfully. Carefully devised work samples based on job analysis data determine the knowledge, skills, and abilities needed for each job. Then, each work sample element is matched with a corresponding job performance element. For example, a work sample for a customer service representative at Wells Fargo Bank may involve keyboard computation: the applicant performs computations during a customer transaction. At Lowe ’ s, a potential cashier is screened for a job that requires scanning the prices of a customer ’ s purchases quickly and accurately. Most candidates first go through a similar work‐sampling session where supervisors demonstrate how to scan accurately, ensuring that the product did indeed ring up. Then the candidate is given an opportunity to show that he or she can handle the job. A test for a retail salesperson or restaurant wait staff may include a role play with a difficult customer. Teaching a sample lesson may be required for a teaching assistant or adjunct professor.tell this in straightforward way from beginning
