In this chapter, we will present data on the assessment of translation/post-editing subcompetencies (English language competence, beliefs about translation, thematic background knowledge), on performance measures (time on task and error numbers) and on the follow-up questionnaire (perceived task difficulty, terminological problems named by students, post-editors’ experiences with the task). This will be followed by examining correlations between performance indicators and perceived task difficulties, as well as between performance indicators and subcompetencies.
