This study investigated the relationship between stages of adult life development and causal attributions for attending college among a sample of nontraditional students. It was hypothesized that the meaning of attending school is reflected in the kinds of attributions that are given for attending school. It was also hypothesized that internal attributions are more common at later stages of adult life development. The findings confirmed the existence of internal and external (career and situational) cognitive attributional dimensions, with the internal dimension being the strongest. Coherent stages of adult life development were identified, which corresponded to a transitional stage, an early adult stage, and a mid‐adult stage. Students in the transitional stage were less likely to give external situational attributions, and students in the mid‐life stage were more likely to give external situational attributions. There was also a tendency for internal attributions to increase during the mid‐life phase, although the relationship was not highly significant. The findings are discussed in the context of attribution theory and adult life development theory as well as in terms of implications for educational policy.
