Accessibility Evaluation of Computer Based Tests

Computer-based tests (CBTs) play an important role in the professional career of any person. Universities use CBTs for admissions. Further, many large courses use CBTs for evaluation and grading. Almost all software companies use CBTs to offer jobs. However, many of these CBTs do not take attention to the accessibility barriers for persons with disabilities, specifically visually impaired persons. In this paper, we present a study of accessibility barriers in various CBTs as faced by visually impaired persons in India. These barriers have been identified by a questionnaire survey approach. Our analysis of the responses shows that most CBTs do not meet the expectations of visually impaired persons. We conclude the paper with some recommendations to improve accessibility.
