© 2021 Copyright for this paper by its authors.In the adaptive eLearning system educational measurements are used to control the learning process realized on the feedback approach. Based on the current educational measurements results of the students’ achievements the decision is made on the formation of the educational content given to them at the next stage of learning. To obtain reliable and accurate assessments of the students’ educational achievements, it is necessary to use assessment materials that satisfy the requirements for reliability, homogeneity, discriminatory power, validity and other characteristics. In order to evaluate the values of these quality indicators of assessment tools, it is necessary to do sufficient statistical research of the educational measurements results. At the same time the researcher often encounters the situation when the measurement data are insufficient to achieve the required significance level of the conclusions obtained. In this case assistance in the control decision support can be acquired by analyzing the visual presentation of the educational measurements results. We propose the visual presentation of the assessment materials characteristics, which helps to evaluate the values of quality indicators of assessment tools during the accumulation of new measurement data. This information combined with a visual analysis of the results of students’ achievements makes it possible to identify the trends in the changes of dynamics in students’ competencies and to form the educational control action corresponding to their academic performance levels.
