Three studies examined the perception among college students that school performance is instrumental to future goal attainment. Study 1, an exploratory study involving free report goal assessments, indicated that perceived instrumentality (PI) is a subjectively salient aspect of college students' achievement motivation. Study 2 provided evidence for the structural distinctiveness of PI from self-efficacy, task value, and the achievement goals, and also demonstrated that PI prospectively predicts unique variance in graded performance beyond that accounted for by these motivational variables. Study 3 demonstrated that PI prospectively predicts unique variance in graded performance independently of future time orientation. We argue that a comprehensive understanding of the purposes underlying classroom achievement behavior requires consideration of how school performance may be perceived as instrumental to the attainment of valued life goals.
