Valpar work sample: Tri-Level Measurement

Purpose	click to enlarge
To assess work skills related to inspection and measurement tasks, ranging from simple to very precise.
Procedure
In its standard format, the work sample takes approximately 25 minutes to administer. The evaluee sits in front of the work sample and inspects a total of 61 machined parts, including eleven practice parts. The parts are sorted into nine compartments depending on their measurements and other aspects, which are determined by the evaluee through the use of his or her eyes, a ruler, jigs, a micrometer, and a vernier caliper. The same inspection procedure is followed for each part until or unless it fails a particular test. Defects in the parts range from very obvious malformations to subtle imperfections in length, width, or diameter.
