Passage: The field began to organize under the name "clinical psychology" in 1917 with the founding of the American Association of Clinical Psychology. This only lasted until 1919, after which the American Psychological Association (founded by G. Stanley Hall in 1892) developed a section on Clinical Psychology, which offered certification until 1927. Growth in the field was slow for the next few years when various unconnected psychological organizations came together as the American Association of Applied Psychology in 1930, which would act as the primary forum for psychologists until after World War II when the APA reorganized. In 1945, the APA created what is now called Division 12, its division of clinical psychology, which remains a leading organization in the field. Psychological societies and associations in other English-speaking countries developed similar divisions, including in Britain, Canada, Australia, and New Zealand.
