<mods:abstract>The lack of students interested in pursuing science, technology, engineering, and mathematics (STEM)-related careers calls for studies that identify variables affecting their career decisions. By drawing on recent conceptualizations of the cost domain first introduced in the expectancy-value theory of achievement motivations, this study investigated whether the perceived difficulty of school science predicted and affected elementary school students (N = 245) task effort and loss of valued alternatives experienced while engaging in a science-related course. Hierarchical multiple regression analysis revealed that students’ perceived difficulty significantly predicted levels of cost experienced when studying science. Likewise, multi-factor ANOVAs revealed that students perceiving school science as a difficult subject reported significantly higher levels of task effort and loss of valued alternatives related to studying science. These findings suggest that the attitudinal dimensions of perceived difficulty play a promising role in the development of cost in science, which has valuable implications for repairing the leaky STEM pipeline.</mods:abstract>
