1. Enrolling in Scientology courses. Traditionally, this has been done in a Scientology classroom, called an Academy. Some classes can also be done at home with any written lessons turned in via mail or email.

There are dozens of courses. Beginning courses are usually oriented toward addressing trouble areas in life. Some of the subjects addressed are: communication with others, marriage improvement, problems at work, and more.

2. Training can also refer specifically to Auditor Training.

While some courses apply to various areas of self-improvement, there is a series of courses one does to become an auditor.

When a person is at any point in their auditor training lineup they are said to be doing their training.

The left side of the Grade Chart shows the main training courses one does to complete the training part of the Bridge. This is auditor training. There are some other training courses not listed on the Grade Chart. They are done as needed.

Here are the first several auditor training levels starting with their prerequisites:


Student Hat — teaches the technology of study. By the end, the student should feel confident they can tackle any subject, including auditor training.

Method One — an auditing action that finds and clears up misunderstood words in every subject a person has studied. This can be done as a course where two people learn the skill and then pair up to deliver this action to one another. In this case, it is done under the guidance of a course supervisor.

Communications Course (aka Professional TRs Course) — one studies all about communication and does intensive training on each part of the communication cycle. By the end, the student should feel able to face and situation in life or as an auditor using communication.

Once the auditor has completed the prerequisites, they can move on to the Academy Levels. Each level trains the auditor to counsel a preclear in the corresponding Grade Chart action, which is called a Grade.

Level vs Class vs Grade 

These 3 words can be confusing until you get the hang of them.

Level is the word used when someone is taking an auditing course. For example, “Mickey is doing her Level 0.” That means Mickey is taking the auditor training course called Level 0.
Class is the word applied to someone who has completed an auditing course. They are then certified and classified as that kind of auditor. For example, “Harry just finished Level II. He is now a Class II Auditor.”
Grade is the word for the auditing actions done with the preclear. For example, “Now that Sophia has completed her Level IV training, she has gotten certified as a Class IV Auditor. Next she will deliver Grade IV Auditing to her preclear, Alan.”

Auditor Training and Processing Names

Academy Levels:

Academy Level 0 aka Hubbard Recognized Scientologist (HRS) — teaches the basic skills needed to audit. Once that portion is completed, the auditor learns the techniques used to audit someone on ARC SW and  Grade 0.

Academy Level I aka Hubbard Trained Scientologist (HTS) — in this course the auditor learns to resolve problems and enable a preclear to spot and dissolve sources of problems in life. The auditor also learn how to audit objectives processes.

Academy Level II aka Hubbard Certified Auditor (HCA) — educates the auditor in processes to help with responsibility and integrity. And specifically trains one in how to address overt acts and withholds.

Academy Level III aka Hubbard Professional Auditor (HPA) — trains the auditor to process upsets that are holding the preclear down in life. And learns to audit changes that have had an adverse effect on the preclear.

Academy Level IV aka Hubbard Advanced Auditor (HAA) — instructs the student auditor in processing fixed conditions in life.

There is more training beyond these, but they are no longer referred to as levels. You can see the names of them on the Grade Chart.
