The research is devoted to developing a criteria-based assessment complex for monitoring students' academic achievements in computer science. The study aims to create a program implementation of an effective monitoring system that will improve the quality of the educational process and the satisfaction of both students and teachers. Within the framework of the study, the following tasks were set: analysis of existing methods for evaluating educational achievements; development of the architecture of a criteria-based assessment complex, including automated assessment mechanisms; and conducting an empirical study to validate the developed complex and its impact on student academic performance. The research methodology includes theoretical analysis, survey, and data analysis methods used to assess the system implementation's effectiveness and to receive feedback from teachers and students. The significance of this research lies in developing an innovative approach to assessing educational achievements, which can be adapted and applied in various educational institutions. The study's results can serve as a basis for further research in educational technologies and assessment of the quality of education.
