The Oxford Capacity Analysis (OCA), also known as the American Personality Analysis, is a list of questions which is advertised as being a personality test and that is administered for free by the Church of Scientology. The OCA test is offered by the Church of Scientology online, at its local churches, and sometimes at local fairs, carnivals, and in other public settings. It has no relation to the University of Oxford, although the name may have been chosen to imply so.
The test is an important part of Scientology recruitment and is used worldwide by the Church of Scientology to attract new members. However, it is not a scientifically recognized test and has been criticized by numerous psychology organizations, who point out that it is "not a genuine personality test" and allege that Scientologists use it in a "highly manipulative" and "manifestly unethical" fashion.
