In evaluating competency-based education, effective test instruments must address real-life complexities. The impact of subject-specific, linguistic, and contextual task features, alongside central personal characteristics, on the empirical challenge of such tasks is unclear. We developed mathematics tasks from 30 real-world contexts, each with three questions of varying complexity, administered through a systematically rotated experimental design to 535 German grades 9 and 10 students. Various student variables were collected. Generalized linear mixed models revealed that contextual and mathematical task features significantly contributed to task difficulty variance. Language features had no intermediate-level influence, while students' mathematical self-efficacy moderated low task context familiarity's impact. These findings guide the construction of reality-based mathematics tasks to tailor empirical difficulty. In the context of worldwide competence-orientated education, it is crucial to reform in-class and national tests. Traditional task formats are limited in representing authentic problems. In most school subjects, a lack of understanding exists in designing reality-based competence-oriented tasks that ensure fair test conditions and meet the subjects' normative demands. This study addresses this gap by empirically investigating the interplay of subject-related, linguistic, and contextual aspects of reality-based tasks in mathematics. Teachers and researchers can use these insights to improve competence-oriented performance situations, sparking further questions. These findings encourage similar studies across subjects for broader applicability. •Contextual and mathematical task features contribute to a task's difficulty.•Language features have no influence on task difficulty at an intermediate level.•Mathematical self-efficacy moderates the influence of low-context familiarity.•Test items for competency-based education need a more multi-layered consideration.
