These TRs, numbered 0–4, emphasize Scientology's "cycle of communication".
OT TR-0: Operating Thetan confronting Two students sit facing each other with their eyes closed, sometimes for hours. The routine ends when both students can sit for an extended period without movement or drowsiness.
TR-0: Confronting In the first exercise, a student and coach face each other with eyes open. The routine ends when the student can confront the coach for at least two hours without movement, excessive blinking, or loss of attention. The second exercise is the same, except that the coach tries to distract the student both verbally and physically. According to Jon Atack, "critics of Scientology usually mention the 'relentless stare' which for the great majority of Scientologists is habitual.
TR-0: Bullbait The coach says things to the student to try to provoke a reaction, including teasing, joking and yelling. The coach may say or do anything except leaving the chair. The student must be able to sit and watch the coach without getting distracted or reacting in any way. If he does, the coach flunks him and the TR starts over. The coach will attempt to find the student's "buttons" (things that cause a reaction). The stated purpose of this TR is to train the student to
be there in a communication situation without getting distracted.
TR-1: Dear Alice The student reads several lines from
Alice in Wonderland to the coach as if saying them himself. The coach either acknowledges the line or flunks the student according to whether the line is communicated clearly.
TR-2: Acknowledgements The coach reads the student lines from
Alice in Wonderland in a reversal of TR-1. The student must acknowledge each line so as to clearly end the cycle of communication.
TR-3: Duplicative question The student repeatedly asks the coach, "Do birds fly?" or "Do fish swim?" If the coach answers the question, the student acknowledges the answer. If the coach says anything else, the student advises the coach that he will repeat the question, and then does so.
TR-4: Originations The student repeatedly asks the coach a question as in TR-3. If the coach originates a statement unrelated to the question, the student handles the origination as needed and then continues the routine. == Control drills ==
