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 that Scientology recruiters use it in a highly
manipulative and unethical fashion.

Questions
Two hundred questions make up the Scientology personality test. Each can be answered 'yes', 'no', or 'maybe'. Typical questions include:

The OCA test is often given at the same time as a "Novis Mental Ability Test," a short 30 minute test which Scientology recruiters claim measures
IQ. After the two tests have been completed, a computer program is used to plot the results on a personality profile graph. This gives the testee's IQ rating and score in personality characteristics such as "Stable," "Happy," "Composed," "Certainty," "Active," "Aggressive," "Responsible (Causative)," "Correct Estimation" (meaning the testee's ability to look at a situation and determine what is needed to deal with it), "Appreciative," and "Comm
nicationLevel" (meaning the testee's ability to communicate with others).
The scale on the graph of each trait ranges from +100 to −100, with three main bands marked "Desirable State" (+100 to +30), "Normal" (+30 to 0) and "Unacceptable State" (0 to −100). In the middle are two shaded bands, "Acceptable under perfect conditions" (about +32 to about +6) and "Attention Desirable" (about +6 to about −18). A legend at the foot of the graph sheet warns that a point below the latter band indicates "Attention Urgent."
After the graph has been plotted, a Scientology staff member reviews the results with the testee.

exams, including the California Test for Mental Maturity.
In the mid-1950s, the project to create Hubbard's own test began, with Hubbard commissioning a longtime follower, Julia Salman Lewis, to produce one. Her first effort, the American Personality Analysis (APA), failed to satisfy Hubbard so, in 1959, he asked a friend and Scientologist, Ray Kemp, to broaden the scope of the test. Wrote Kemp:
The Scientology organization first announced its test in an article by Kemp, who hailed the OCA in the pages of ''Certainty'', the magazine of the
Hubbard Association of Scientologists in London. Later, the church gave credit to Hubbard for the test and trademarked the terms "OCA" and "Oxford Capacity Analysis." The copyright holder is

in 1960, the organization began to use the test on members of the public. The South African campaign had kicked off with a newspaper ad:
Respondents were tested in the Johannesburg Scientology office, having been told:
Hubbard proclaimed it "the hottest, fastest procurement service set up we have ever had." He announced that the new "Personal Efficiency Test Program," utilising the OCA, would be rolled out across Scientology in the next few months. Since then, OCA tests have been one of the most visible means by which the Church of Scientology attempts to attract new members.
Use within Scientology
The OCA is today used for two principal purposes. Within the Church of Scientology, it is used to test for improvement in the personality of a "
preclear" (a Scientologist who is getting auditing) and the effectiveness of the chosen Scientology "process". OCA evaluations are conducted regularly and recorded, following Hubbard's instructions:
The other use, more visible to non-Scientologists, is that of recruitment, using the OCA as a tool to attract new people for Scientology services. In a 1960 policy letter, Hubbard wrote:
The results of the test are invariably negative, as various reporters have found:
Former Scientologists have spoken of how everything that is ostensibly defective in a person is purposefully emphasized in OCA test results.
["Scientology Tests' Purpose And Validity Are Questioned", ''Buffalo News'' (New York), February 2, 2005] Individuals who have undertaken the OCA have described how they were given just such negative evaluations; as one young Sydney woman put it in an interview in 1980:
Hubbard advised that the hopelessness of the testee's predicament (or "ruin," as he put it) should be emphasized by the tester, who should continually state that Scientology services are what is necessary for the situation to be salvaged:
The evaluator generally follows a script (pre-written answers based on the test taker's score) originally devised by South African Scientologist Peter Greene around 1960/1961, which Hubbard instructs "must be studied and learned by heart" by evaluators. Although the analysis is represented as being "not our opinion of you, but
..a factual scientific analysis taken from your answers,"
[Hubbard, "Evaluation Script", HCO Policy Letter of February 15, 1961] it relies heavily on scripted responses set out in detail in the "OCA Automatic Evaluation Script".
The evaluator is instructed to recommend Scientology as the only viable remedy for such problems. Alternatives are to be mentioned – "psychology, psychoanalysis, Dale Carnegie, Confidence Courses, Mental Exercises"
– but only for the purpose of dismissing them: "these things had a very limited application and you could get yourself terribly involved in mysteries, expenses and wasted time, before you found any solutions to your difficulties. All across the world today, people are coming to us, to find simpler, more straight forward answers."
The vehemence with which OCA test evaluators attempt to "impinge" has attracted comment from non-Scientologists who have undergone the test. Writing in 1970, a British psychologist who underwent the test noted that:
If an IQ test is added to the regular OCA examination, Scientology is likewise promoted as being essential no matter what the results – for everything from raising a low IQ to managing a high IQ. Hubbard provides four levels of grading for this test, for each of which there is a scripted response:
Use outside Scientology
The OCA is licensed to Scientologist-owned companies through the
World Institute of Scientology Enterprises. It has been used for a variety of purposes, most commonly employee screening.
["Brutal Psyche Tests Bring The Sack", ''Sunday Mail'' (Queensland), December 9, 1990]
Some Scientologist doctors use the test to evaluate patients. Los Angeles celebrity plastic surgeon Dr. Edward Terino rates his patients on a "Trouble Scale" after administering the test, which he markets to doctors via a company called Surgeon's Insight. Terino, a Scientologist, adopted the test after being threatened with injuries by a husband who hated Terino's nose-job work.
It has often been used without alteration, but has also been issued in modified versions; for instance, MasterTech markets the OCA with minor changes and calls it the Personnel Potential Analysis Test.
Criticism and controversy
Psychologists have assailed the test's lack of scientific basis. Other critics call it intentionally manipulative and humiliating.
