    Abstract
    This paper reports on an exploratory study with the aim to validate item response processes in digital competence assessment through eye-tracking techniques. When measuring complex cognitive constructs, it is crucial to correctly design the evaluation items to trigger the intended knowledge and skills. Furthermore, to assess the validity of a test requires considering not only the content of the evaluation tasks involved in the test, but also whether examinees respond to the tasks by engaging construct-relevant response processes. The eye tracking observations helped to fill an ‘explanatory gap’ by providing data on variation in item response processes that are not captured by other sources of process data such as think aloud protocols or computer-generated log files. We proposed a set of metrics that could help test designers to validate the different item formats used in the evaluation of digital competence. The gaze data provided detailed information on test item response strategies, ...
