Purpose: To assess work skills that require proper selection, placement and use of a variety of hand tools according to instructions and routine. The work involves assembling articles, fastening them together with bolts and washers, driving objects into grooves, and moderately precise, light hammering. The work sample simulates light and sedentary work and assesses the following physical demands: reaching, handling, fingering, near acuity, and depth perception. Significant spatial aptitude, motor coordination, finger dexterity and manual dexterity are called for to perform the work sample at a competitive level.

The work sample elicits information on several worker characteristics, including, among others, the ability to follow instructions, concentration skills, communication skills, frustration tolerance and the ability to conceptualize problems.

The work sample is well suited to work-hardening applications.

Design: Hands-on work sample hardware used in four separate exercises.

Special Features: Scores may be interpreted against criterion-referenced standards or locally developed norms. It is appropriate for use with disabled or nondisabled persons.

Information Collected: Each of the four exercises of the work sample has been analyzed according to U.S. Department of Labor job analysis techniques. The analyses resulted in four lists of rated DOL work-related abilities and other factors required for successful work sample performance. Valpar uses Methods-Time-Measurement (MTM) to establish industrial work rate standards for the four exercises. Successful performance requires a variety of DOL aptitudes, physical demands, and other factors.

The evaluator uses learning curve adjusted MTM standards to determine whether the evaluee has demonstrated the work sample exercises’ Worker Qualifications Profiles. Unadjusted MTM standards are also given for both single and multiple administrations of the four exercises.

Procedures: Due to the short duration of the exercises, multiple administrations are recommended (but not required). In their standard format, all four exercises take approximately 40 minutes to administer.

In the Assembly exercise, the evaluee uses wrenches to assemble two halves of a block, using four bolts, springs, washers and nuts.

In the Alignment and Driving exercise, the evaluee drives several bars through holes in the block assembled in the first exercise. The evaluee must use a rubber mallet, punch, wrench, and ball peen hammer.

In the disassembly exercise, the evaluee must disassemble the block, putting all parts and tools back into their proper places.

In the hammering exercise, the evaluee uses an inked claw hammer to tap marks onto targets on hammering sheets.
