Abstract

Since the quality of measuring in international practice is assessed by uncertainty of the results, and an apparatus for its calculation in the area of expert measurement has not been developed yet, the study focuses on the methods of estimating uncertainty of expert measurement results.

The authors have conducted analytical research on the sources of expert measurement results’ uncertainty, among which the main ones herewith singled out are: imperfection of experts, wrong choice of their number, and assessment conditions. The system of expert quality indices and the methods of their identification are suggested in the article. It enables making the right choice of the optimum methods of estimating the expert quality indices in any concrete case. The expert assessment of the significance of student activity components with regard to their uncertainty calculation has proved that the most important component is a “study activity”, and the least important one is a “social activity”.

The suggested recommendations for standardizing the specialist experts’ quality indices suggest setting the lower limits of the admissible values. It allows normalizing their characteristics and optimizing the process of their attestation and hereby ensures coherence in expert measurements.
