This article will examine the professionalization of psychology in North America, focusing specifically on clinical psychology. First, I will cover a broad history of clinical psychology and its development over time. Second, I will focus on developing professional psychological training programs. It is important to keep in mind the impact of sociopolitical factors on the professionalization of psychology. A major influence on professionalization was World War II: it helped bring applied fields out of obscurity and required training in mental testing and psychotherapy. Next, I will discuss the emergence of organizations such as the Canadian Psychological Association (CPA) and the American Psychological Association (APA) and their influence on psychology training programs in academia. The battle between psychology as a science and psychology as a profession will be examined. Finally, the history of psychology at Acadia University will be explored by relating it to the significant changes that occurred in the boundary sphere of psychology during a 40-year period, 1935-1975. Acadia has a very rich history and strong ties to the CPA that led to the creation of a clinical program well before the time of its professionalization and the creation of a code of ethics. Additionally, the Maritime Provinces were the first to have a provincial association of professional psychologists thanks to W. H. D. Vernon, a professor at Acadia University. someone who is grieving. Furthermore, people in decades past suffered from similar problems as today. B......half of the article......biology in Canada during that period includes fourteen articles in the 1946 issue of The CPA Bulletin (Conway, 2010). Although psychology as a professional has made progress, it has faced some backlash from academia. Skepticism about the professionalization of psychology was still present in the 1950s. At some universities, psychology still struggled to maintain its identity as a department. The production of a code of ethics can be seen as a fundamental aspect of the professionalisation of a profession. A code of ethics is a set of regulatory practices that protect the public from unethical treatment. In 1948, the CPA established the Canadian Board of Examiners in Professional Psychology (CBEPP). However, at that time the Association did not have the resources to establish national standards and began certifying Canadian psychologists through the APA (Dunbar, 1998).
