In general, certified project management professionals are perceived to enhance project performance. However, this narrative has quite often been challenged in previous literature. We investigate this controversy by including professionalism and psychological capital as intervening variables. The research is based on an empirical survey of certified project managers in the region of Rawalpindi/Islamabad. 373 data samples were collected and further analyzed on the basis of critical success factor theory. The impact of project management certification along with intervening variables were hypothesized and validated to have direct and indirect relationships with project performance. Responses from certified project management professionals in the region of Rawalpindi/Islamabad support the perception but reflect that professionalism plays a supporting role between certification and performance. However, the study dismisses the role of psychological capital between professionalism and performance. We conclude that project management institutes and associations should ensure professionalism in the certification process to actually enhance project performance. The findings contribute to the body of knowledge in predicting improved project management performance by employing certified project managers with strong professional skills. Consequently, the research will help professional institutes to review the conformity of the required professional skills rather than just focusing on just passing an exam.
