The subject of the article is a problem of the Likert’s scale validity as a method of measurement. The author on the basis of empirical findings discusses the issue of prognostic credibility of results while measuring the attitudes applying the Likert’s method. The basic question concerns the agreement of the prognosis that bases on the attitudes’ measurement data, with the actual bahavior. Six scales characterizing the different aspects of attitudes toward work conditions have been employed in the investigations. Subsequently, the findings have been compared to the actual workers’ efficiency. The result allows for an assumption, that utility of a technique considered as the prognostic tool is very limited. In the majority of cases, the results of measurement differed significantly from the data relating to the actual behavior. Almost satisfactory agreement has been reached in case of one scale only. This testifies inaccuracy and at the same time, unrealiability of measurement with that metod and requires caution in employing it as the instrument of prediction.
