As both high self-efficacy beliefs (Bandura, 1997) and forming implementation intentions (Gollwitzer & Sheeran, 2006) are known to improve goal attainment, it is suggested that implementation intentions geared at strengthening self-efficacy should be a very helpful self-regulation strategy to achieve high scholastic test scores. In Study 1, female participants had to perform a math test either with the goal intention of solving as many problems as possible or with an additional selfefficacy strengthening implementation intention. In Study 2, male participants worked on an analytic reasoning test under either a mere achievement goal intention, an additional self-efficacy strengthening implementation intention, or an additional self-efficacy strengthening goal intention. In both studies, participants with self-efficacy strengthening implementation intentions outperformed the mere achievement goal intention participants. Moreover, Study 2 showed that additional self-efficacy strengthening goal intentions were not as effective as additional selfefficacy strengthening implementation intentions. The results are discussed in terms of their contribution to research on both self-efficacy and implementation intentions.Self-efficacy is defined as a personal judgment of one's ability to perform actions leading to desired outcomes (Bandura, 1997). Expectations of personal efficacy determine which goals people choose, whether they initiate the relevant actions, how much effort they will expend in doing so, and how long effort will be sustained in the face of adversity. People who have a low sense of self-efficacy are easily discouraged by failure, whereas those who feel able to perform critical goal-directed actions intensify their efforts when their performances fall short. By affecting people's acceptance of challenges, persistence despite setbacks, execution of complex cognitive strategies, and calmness versus anxiety in the face of threat, higher selfefficacy perceptions generally promote superior performance.Two decades of empirical research point to the positive relationship of selfefficacy and respective achievements in different domains (e.g
