摘要：Accessibility level of websites of leading educational institutions� websites has been determined through analysing compliance with the levels of accessibility under WCAG 2.1; the results obtained enable to develop hierarchical model of accessibility evaluation taking into account criteria and sub-criteria factors. Qualitative formation of the electronic system of education in fundamental and technical disciplines shall enable to provide students, regardless of health defects, with high-quality education, ensuring development of European countries in the sphere of science in accordance with international standards. High quality of the websites of the following educational institutions has been detected: 3% for the University of Michigan Ann Arbor and 6% for the University of Cambridge, for other educational institutions it is in range from 13% to 38% (for 40 scanned pages). The website of U701 University for 100 scanned pages is characterized by minimum of 9% accessibility, 2% compatibility and 31% compliance with web standards. Massachusetts Institute of Technology has 35 pages with the problem of accessibility. National Technical University �Ihor Sikorskyi Kyiv Polytechnic Institute� has 22 pages with accessibility problem. Low accessibility level has been detected at Lviv Polytechnic National University; it has 80 pages of the website with problems for users, including those with disabilities. The proposed hierarchical model of evaluation of quality of websites by criteria and sub-criteria factors shall form accessible websites to users, improve access to them regardless of functional disorders, reducing the duration and effort to search for information.
