Wire bending test

from Wikipedia, the free encyclopedia

The wire bending test is a job-related performance test . The task is to process wires manually according to a given template. The participants have a maximum of twelve minutes per figure, whereby the processing time does not play a role in the assessment (i.e. it is a so-called power test / level test ). The end product is assessed on the basis of various criteria, such as the accuracy of the shape or the "cleanliness" of the solution. A total of 29 individual criteria are relevant for the assessment.

The process is particularly suitable for use in the metalworking professions. The second edition of the wire bending test has been on the market for over 40 years and is a classic method for diagnosing so-called manual dexterity. The implementation time is about half an hour. Precursors of the wire bending test were used at the Carl Zeiss company in Jena (Immig, 1920).

Test quality

The reliability of the test can be rated as high: Retest reliability values ​​around .80 were calculated (Häcker & Stapf, 2009). The wire bending test has a high content validity - also called visual validity. This means that the tasks are based very closely on the actual practical requirements. The normalization was carried out on 1,573 adolescents and 125 adults.
