Modern assessments are increasingly based on complex test materials, which are often implemented as simulations. These interactive assessment instruments enable students to use the system in various ways. For this reason, students' interactions with a test delivery platform are stored in automatically generated log files but during the assessment process a large amount of log data is accumulated with various characteristics (clicking, typed answers, and timing-related data). For an efficient analysis of these human-computer interactions' data, it is necessary to gain information about the actual test-taking processes. One very promising way of examining test-taking behaviour is visual data exploration, which is focused in our study. The main objective of this paper is to illustrate how information visualization can help the educational measurement with exploring students' activities in computer-based assessment. It gives insights into visual representations that are useful in depicting test-taking behaviour, identifying trends in students' activities in simulation-based assessment, and examining individual differences on the grounds of test-taking processes. We therefore applied tools and visualization layouts, which support educational practitioners in making use of the data assembled in computerized test delivery.
