Based in Washington, D.C., the American Psychological Association (APA) is a scientific and professional organization that represents psychology in the United States. With 150,000 members, APA is the largest association of psychologists worldwide.
APA seeks to advance psychology as a science, a profession, and as a means of promoting health, education, and human welfare. We do this by:
Encouraging the development and application of psychology in the broadest manner Promoting research in psychology, the improvement of research methods and conditions, and the application of research findings Improving the qualifications and usefulness of psychologists by establishing high standards of ethics, conduct, education, and achievement Increasing and disseminating psychological knowledge through meetings, professional contacts, reports, papers, discussions, and publications Adapted from APA Bylaws I.1
