Die ontwerp van 'n werkmonstertoets vir die keuring van swart elektrisienambagmanhelpers

A work sample test, the Cable Joints Test, which could serve as a selection instrument for Black electrician aides in the mining industry was designed and applied with a rating scale as criterion. The predictors were scores on two testings with the work sample, an improvement score, Dudec and related job experience. A validation study (N=53) yielded low reliability coefficients and no significant correlation between predictors and criterion, but a cross validation (N=62) had shown that a combination of the second test score and Dudec combined could predict work performance. However, the multiple correlations (0,40 to 0,52) were low and the variance explained inadequate to be of any practical value in a selection battery. Opsomming 'n Werkmonstertoets, die Kabellastoets, wat kan dien as keuringinstrument vir Swart elektrisiënambagmanhelpers in die mynbouindustrie is ontwerp en toegepas met 'n beoordeling- skaal as kriterium. Die voorspellers was tellings op twee toetsings met die werkmonster, 'n verbeteringtelling, Dudec en verwante werkervaring. 'n Valideringstudie (N=53) het lae betroubaarheidskoëffisiënte en geen betekenisvolle korrelasies tussen voorspellers en kriterium opgelewer nie, maar 'n kruisvalidering (N=62) het aangetoon dat 'n kombinasie van die tweede toetstelling en Dudec werkverrigting kan voorspel. Die meervoudige korrelasies (0,40 tot 0,52) was egter laag en die variansie wat verklaar word onvoldoende om van enige praktiese waarde in 'n keuringbattery te wees.
