The Bridge to Total Freedom is displayed as a large wall chart, printed with red ink on white paper. There are two main columns: "Training" on the left and "Processing" on the right. A newcomer to Scientology starts the Bridge at the bottom of the chart and rises through the levels, perhaps reaching the level of Clear, then continuing upward through the
OT Levels to higher states of awareness and ability. The section near the bottom of the chart covers the various routes onto the Bridge which can include a communication course, a life improvement course, introductory auditing, and other basic services. The far left margin lists extra training courses that are available but which are not required for going up the Bridge. Likewise, the far right margin lists extra auditing processes that a Scientologist can do that are not part of the steps up the Bridge. The terms "The Bridge to Total Freedom" and "Classification, Gradation and Awareness Chart" are synonymous with each other, with the Bridge being used more to express the concept of the steps and the chart name being used more to refer to the diagram on the wall. The word
Classification refers to the large left column, "Training". Once a student has completed one of these training levels, they become a classed auditor. For example, completing the Class II course, a student becomes a Class II auditor. The word
Gradation refers to the large right column, "Processing". In the 1965 version of the Bridge, a much less comprehensive chart than is used today, the beginning Scientologist would move up through the "grades" to Clear. The word
Awareness refers to the center area between the two large columns where there are 52 levels of awareness from
Unexistence at the very bottom up to the state of Clear. The training and processing sides go hand-in-hand for each level of the chart. For example, a student completing the Class III course is qualified to
audit someone on Grade III, and two students can train on a level and then
co-audit each other. Likewise, a Scientologist wanting to participate in Grade III will need an auditor who has trained at least to Class III. Although the chart lists 15 OT levels above the state of Clear, only seven were released during Hubbard's lifetime.
OT VIII was released to the public in 1988, two years after Hubbard's 1986 death — to be performed
only on Scientology's ship
Freewinds. According to interviews performed by Rinder, Scientologists have described OT VIII as "less than overwhelming". Since 1986, Church of Scientology leader
David Miscavige has dangled the hope of OT levels beyond VIII being released in the future, pending certain conditions, which have shifted over time. However, it has been widely reported that Hubbard never wrote OT IX and above; therefore, these levels do not officially exist. Though many Scientologists only ascend the processing side of the Bridge, Hubbard maintained that a person needed to receive auditing
and give counseling to another; that 50% of the gains in Scientology were achieved through training as an auditor. == Costs ==
