Purpose: To assess the ability to perform repetitive assembly work requiring manipulation and bilateral use of the upper extremities. The work sample simulates light work and makes the following physical demands upon the evaluee: reaching, handling, fingering, feeling, near acuity, depth perception, accommodation, and field of vision. Significant motor coordination, finger dexterity, and manual dexterity are required to perform the work sample at a competitive level.
The work sample elicits information on several work-related characteristics, including, among others, the evaluee’s ability to follow instructions; and his or her stamina, self-confidence, and motivation.
The work sample is well suited to work-hardening purposes.
Design: Hands-on work sample hardware is manipulated by the evaluee in one 20 minute exercise. The work sample requires a 110V grounded outlet.
Special Features: Scores may be interpreted against criterion-referenced standards, supplied norms, or locally developed norms. It is appropriate for use with disabled or nondisabled persons. A VCWS#8 B-Kit — adaptation for visually impaired or blind persons — is available.
Information Collected: The work sample has been analyzed according to U.S. Department of Labor job analysis techniques. The result of the analysis is a list of rated DOL work-related abilities and other factors that are required for successful work sample performance. Valpar uses Methods-Time Measurement (MTM) to establish industrial work rate standards for the work sample. Successful performance requires a variety of DOL aptitudes, physical demands, and other factors (Worker Qualifications Profile).
Using MTM standards that have been adjusted for learning, the evaluator uses the number of assemblies score to determine whether the evaluee has demonstrated the work sample’s Worker Qualifications Profile. Unadjusted MTM standards are also provided.
Procedure: The work sample exercise is characteristic of conveyor-assembly jobs in which the product moves toward and away from workers on an assembly line. The evaluee is positioned in front of the work sample, and, as the assembly wheel turns at a constant speed, he or she makes as many three-part assembly operations as possible within the 20 minute time limit. First, the evaluee places a pin in a hole on the assembly wheel. Next, he or she places a spacer on the pin, and finally a cap on top of the spacer. Correct assemblies are automatically counted and recycled back into parts bins at the front of the work sample.
Components: The work sample is a box 27 3/4″ x 23 3/4″ x 11 1/2″ made of particle board and covered with blue, plastic laminate. It has an 18″ diameter assembly wheel which is driven by a gear motor. The speed of the wheel can be adjusted up to 12.5 RPM. On the left side of the box is a unit assembly counter and an off/on switch. A motor speed control is located beneath the hinged lid at the rear left of the box. The front of the work sample is divided into two work trays which contain 12 assembly pins and 12 each white and black assembly parts. The work sample comes with a pad of 100 scoring sheets and a manual.
