Purpose: To assess work skills required in drafting occupations. The work sample may be used to assess both current levels of achievement and potential for achievement in drafting skills. VCWS 16 simulates sedentary work and makes the following physical demands upon the evaluee: reaching, handling, fingering, near acuity, depth perception, and visual accommodation. There are six scored exercises in VCWS 16 that range from simple measuring tasks to relatively complex drafting and blueprint reading. The later exercises require significant degrees of spatial aptitude, form perception, motor coordination, finger dexterity, and manual dexterity to perform at a competitive level.

The work sample elicits information on several work-related characteristics, including concentration skills, communication skills, ability to follow instructions, memory, frustration tolerance and others.

Design: Hands-on work sample hardware in six separately scored exercises that increase in difficulty as well as an orientation and practice section.

Special Features: Scores may be interpreted against criterion-referenced standards or locally developed norms.

Information Collected: Each of the six exercises of the work sample has been analyzed according to U.S. Department of labor job analysis techniques. Each exercise has its own list of rated DOL work-related abilities and other factors that are required for successful exercise performance. These lists are called Worker Qualifications Profiles or WQPs.

Valpar uses Methods-Time Measurement (MTM) to establish industrial work rate standards for the work sample exercises. The evaluator uses work rate and accuracy scores to determine whether the evaluee has demonstrated each exercise’s WQP.

Procedures: The time of administration varies; the more successful the evaluee is, the longer the work sample takes. Up to two hours, or even longer in some cases, may be required for all six exercises.

Section A familiarizes the evaluee with the tools used in the scored exercises.Section B (Measuring): The evaluee examines an answer sheet that depicts three rulers with different units of measurement. Various lengths have been marked on each ruler which the evaluee must decipher.

Section C (Line Perception): The evaluee duplicates 10 line drawings presented on an answer sheet.

Section D (Use of Ruler, T-Square, and Triangle): Using the indicated instruments, the evaluee duplicates three designs that are labeled with measurements and depicted on the work sample.

Section E (Use of Compass and Circle Template): Using the indicated instruments, the evaluee duplicates three designs that are labeled with measurements and depicted on the work sample.

Section F (Blueprint Reading): The evaluee answers 22 questions concerning measurements of several diagrams (blueprints) depicted on the work sample.

Section G (Orthographic Projection/Drafting): Using a three-dimensional, labeled diagram as a model, the evaluee measures, diagrams, and labels three views each of three variously shaped blocks.

Components:VCWS 16 is a square box, 23 1/2″ x 3 1/2″ constructed of particle board and covered with blue plastic laminate. It comes with a hinged lid that serves as the drafting surface. Inside the box is a 22″ x 23 1/2″ x 58″ surface which mounts vertically on the back of the box. Several diagrams are situated on this surface and arranged by partially closing the lid, which comes to rest at an angle approximately 25 degrees.
