Per policy they always include KSW and Tech Degrades at the beginning of every course and star rate them.

* HCOPL 7 FEB 65 Keeping Scientology Working
Reissued 15 Jun 70 and corrected 28 Jan 73 on the 1974 checksheet. The 1987 has the even later revision which makes it KSW series 1. Oddly enough, the version in the new tech volumes (NVS1) simply has the original date of 7 FEB 65 with no revision history or date, but it has all the later revisions in the text.

* HCOPL 17 JUN 70 Technical Degrades on the 1974 checksheet.
The 1987 checksheet has the 17 Jun 70RB version of 25 Oct 83 which makes this KSW Series 5R.

The 1974 checksheet also includes the following which are not on the newer checksheet. Note that many of these are policies and therefore are not usually in the tech volumes.



HCOB 25 JUN 71R revised 25 NOV 74 BARRIERS TO STUDY (word clearing series 3R) (TV 7) (NTV 9)

* HCOPL 22 NOV 67 rev 18 JUL 70 Out Tech

* HCOPL 8 JUN 70 Student Auditing
(the 11 JAN 85 revision of this one is on the 1987 checksheet but at a later point).

Note that student auditing policies varied over the years as to whether the students could co-audit or audit freecenter preclears or audit staff members etc.


The 1987 checksheet has -

The Classification, Gradation and Awareness chart of Levels and Certificates - Class 0 auditor section, ARC straigtwire expanded and grade 0 expanded sections.

HCOPL 23 OCT 80 R rev 16 NOV 87 Chart of Abilities Gained For Lower Levels and Expanded Lower Grades.
(NTV 12) (TV 13 has the 1980 version)

And they have the student do clay demos of the abilities gained.

The 1974 checksheet has -

BPL 25 JUN 70R rev 11 SEP 74 Expanded Lower Grades Chart of Abilities Gained. (not in either set of TVs)

The really old checksheets just had whatever grade chart was current.


HCOB 25 SEP 71R rev 4 APR 74 Tone Scale in Full (TV 7)
The 1987 checksheet has the 1 APR 78 revision. (TV 14) (NTV 9)

HCOB 26 OCT 70 Obnosis and the Tone Scale.
The 1974 course pack has this as a BTB instead of an HCOB. By 1987 it was back to being an HCOB. (TV 7) (NTV 9)

The 1974 checksheet also has -

BTB 20 JUL 74 Auditor Expertise Drills Series No. 1 - Basic Auditor Drills (which replaces 9 OCT 71 "Basic Drills")

At this point in the checksheet they have the student do drills ED 3 to 8 which have to do with obnosis and the tone scale. The BTB includes ED 1 to 20, some of which are done elsewhere on the checksheet. I did these when they came out and I recommend them highly.

Older class zero checksheets generally had a tone scale section. The slightly older bulletin is 18 SEP 67 SCALES and other earlier versions of this. Sometimes the tone levels were done in clay. Sometimes there was a drill to go around and spot and match tone levels (but not as elaborate as the expertise drills).

The 1987 checksheet has an obnosis drill as follows -
"With another student (who acts as a coach) go around the course room. The coach takes the student around so the student can clearly see other individual students (without interrupting them) and asks the student doing this drill, "What do you see?" The coach accepts nothing that isn't plainly visible. The drill is passed when the student has demonstrated that he can see just what is there visible and plain to the eye.

The Ruth Minshull book "How to choose your people" also provides a good introduction to the tone scale, and the LRH book "Science of Survival" provides a great deal of detail.

The Hubbard College Lectures has an excellent one on the Tone Scale which I would recommend for this section of the course. It is HCL-6 "Emotion" and is in new R&D volume 9.

This level is an excellent time to get a good grounding in the tone scale and in observing people.


Older checksheets used the 1954 auditor's code which can be found in CofHA among other places.

The code was significantly rewritten as part of Class 8 standard tech to the "I promise ..." version.

The 1974 checksheet has * HCOPL 14 OCT 68 The Auditor's Code AD18 plus * HCOPL 2 NOV 68 Auditor's Code additions which added numbers 26 to 28. (TV 6)

The 1987 checksheet has * HCOPL 14 OCT 68RA rev 19 JUN 80. (NTV 8) (TV 14 has it as HCOB 19 JUN 80)

In both cases (and most earlier checksheets), each point of the code was to be demonstrated in clay. Some earlier checksheets also required memorizing and reciting the code from memory.

I would suggest studying both the 1954 code and the AD18 (1968) code. Note that the 1968 code was in use at the hight of quickies. In general the older code is preferable.

It would not be a bad idea to also include an early tape on the auditor's code at this point. I think that the big 1967 checksheet had one of these but I don't recall which one.


Although I would defer meter reading until a more advanced level, the basics of handling a meter are still needed so that the class zero student can handle one in session so as to get used to it and also to note the tone arm (TA) position and recognize a floating needle (FN).

Here both checksheets have the book introducing the e-meter. There is also a book called "Understanding the E-meter" which might be substituted.

* HCOB 14 OCT 68 "You must never never ..." ("Meter Position")

(older copies of the above do not have a title. It begins with the sentence "You must never " and was referred to that way on checksheets including the 1974 checksheet. In later years, the title "Meter Position" appears at the top of the bulletin, but there is no indication of a revision or any corresponding change in copyright or signature etc. It is this way in both TV 6 and NTV 8)

* HCOB 11 MAY 69 Meter Trim Check (TV 6)
(the 1987 checksheet has the 8 JUL 78 revision)
(TV 14) (NTV 8)

BTB 14 JAN 63 (HCOB reissued as a BTB 25 JUL 74) "Rings Causing Rockslams" (not on the 1987 checksheet)
(this is also on the e-meter course checksheet)
(not in either set of TVs)

* HCOB 18 MAR 74 E-meter Sensitivity Errors (TV 8)
(the above is not on the 1987 checksheet)
(the e-meter course checksheet has the 22 FEB 79 revision)
(TV 14) (NTV 10)

HCOB 23 MAY 71 Metering (basic auditing series 11)
(NTV 9) (TV 9)

* HCOB 10 DEC 65 E-Meter Drill Coaching

The emeter course checksheet also includes -

HCOB 7 FEB 79R rev 15 FEB 79 "E-meter drill 5RA can squeeze".
(TV 12) (NTV 11 has the 10 MAR 88 revision)

HCOB 3 SEP 78 Definition of a Rock Slam

False TA positions due to sweaty hands etc. were of great concern in standard tech. I would be inclined to leave this until level I training and simply warn the student not to worry about the TA position too much because it might be false. A case supervisor could allow for this or get it checked out by a higher trained auditor if it was of concern. A beginning auditor should not be overly worried about how the pc is holding the cans, they tend to bother the pc about it and drive them out of session.

In auditing, tone arm action (how much the tone arm moves) is as important as tone arm position, but TA action has always been taught on class I. The two topics are probably best taught together at that level.

Here the 1974 checksheet has

* HCOB 24 OCT 71 False TA
(TV 7) (15 MAY 80 revision in TV 14 and NTV 9)

* HCOB 12 NOV 71 False TA Addition 1
(6 MAR 73 revision in TV 7)
(25 MAY 80 revision in TV 14 and NTV 10)

* HCOB 15 FEB 72 False TA Addition 2
(TV 8) (26 JAN 77 revision in NTV 10)

* HCOB 18 FEB 72 False TA Addition 3
(TV 8) (25 MAY 80 revision in TV 14 and NTV 10)

* HCOB 29 FEB 72R rev 23 NOV 73 False TA Checklist
(TV 8)

* HCOB 23 NOV 73 Dry and Wet Hands Make a False TA
(TV 8) (25 MAY 80 revision in NTV 10)

The 1987 checksheet doesn't give any of the theory but simply has the latest version of the False TA Checklist.

HCOB 21 JAN 77RB rev 25 MAY 80 False TA Checklist
(TV 13) (NTV 11)

The e-meter course checksheet adds the first of the False TA bulletins above.


A level zero auditor should know how to recognize an FN.

But note that strightwire and level zero processes used to be used as processes for setup and case entry in the early days and therefore can be run without proper setup. In those cases one might start without an FN and therefore might not always get an FN when the process completes. The idea of FNing everything did not come into fashion until the 1971 bulletin listed below.

The beginning auditor should not be concerned about getting everything to FN on a new pc. Everything at level zero (and level one as well) can be run to mild wins until the pc begins "flying" (normally FNs at session start and on each process). Once the pc is doing that, it would be an error to leave something without getting it to FN.

Prior to 1970, only the grade itself was taken to an FN rather than the individual processes. This worked when many processes were run (as above) finally leading to a big FN that would persist despite the lack of setups and the presence of out rudiments. As soon as the 1968 standard tech introduced the idea of getting the pc flying first, the single FN produced by a single grade zero process turned out to be an unstable quickie result. So the beginning auditor also needs to know that he should keep going to a major grade completion once the processes do start FNing.

The above is my own interpretation based on combining older and more modern LRH data in this area. The org's standard tech approach would insist on FNing everything and would often require lengthy setups by a higher classed auditor to achieve this.

The 1974 checksheet has -

* HCOB 21 OCT 68 Floating Needles
(TV 6) (NTV 8 and TV 11 have the 9 JUL 77 revision)

* HCOB 11 FEB 66 Free Needles & How to Get Them on a PC
(TV 6) (NTV 8 and TV 12 have the 22 FEB 79 revision)

* HCOB 21 SEP 66 ARC Break Needle

* HCOB 20 FEB 70 Floating Needls & End Phenomena
(TV 7) (NTV 9)

* HCOB 8 OCT 70 Persistent FN
(TV 7) (TV 14 has 30 AUG 80 reissuse as KSW series 19)
(NTV 9 is the reissue without any note about it being a reissue)

* HCOB 21 MAR 74 End Phenomena
(TV 8) (NTV 10)

HCOB 14 MAR 71 FN Everything
(TV 7 and NTV 9 have the 25 JUL 73 revision)

The 1987 checksheet only has two of the above (FN & EP and
Persistent FN) plus the following -

HCOB 10 DEC 76RB revised 25 MAY 80 C/S Series 99RB
Scientology FN and TA Position.
(TV 14) (NTV 10) (original in TV 11)

The e-meter course also has

HCOB 21 JUL 78 What is a floating needle
(TV 12) (NTV 11)

HCOB 2 DEC 80 Floating Needle and TA Position Modified
(TV 13) (NTV 12)


Neither the older checksheets nor the 1974 checksheet required a class zero student to have full metering skills, however the 1987 checksheet does. So it includes a section on instant reads.

HCOB 5 AUG 78 Instant Reads
(TV 12) (NTV 11)

TAPE 25 MAY 62 SHSBC-148/149 E-Meter Data Instant Reads (part 1 & 2)

HCOB 28 FEB 71 Meter Reading Items
(TV 7) (NTV 9)

HCOB 20 SEP 78 An Instant FN is a Read
(TV 12) (NTV 11)

The e-meter course checksheet doesn't include the last two bulletins above but it does include

HCOB 29 APR 69 Assessment and Interest
(TV 6) (NTV 8)

Note that this section is not comparable to full class 3 training on how to read a meter. It is really just enough to get somebody into trouble.

Somebody who has already done class 4 and is retreading level 0 or doing an internship should of course use full metering skills at this level. But trying to get a first time student to accurately read a meter on somebody else (solo is much easier) has always been a big stop on auditor training whenever it was done in this sequence.

It is more important to get the auditor into communication with the pc first. Many of the late era troubles with poor auditing are due to making auditors who are meter technicians rather than communication terminals.


The old level zero checksheets just had drills 1 to 10. The 1974 checksheet has 1 to 21. The 1987 checksheet has all 27.

The 1974 checksheet and the e-meter course checksheet both also include expertise drills CR-3 to CR-5 (the CR stands for cramming) which are in:

BTB 16 JUN 71R rev 30 MAY 73 reisued 22 JUL 74 as BTB "Advanced E-Meter Drills".

All of these fit nicely among the early e-meter drills. I would say that Drill CR 4 "See the session" is essential and of great value. This drill includes doing TR 4 with admin. The 1974 checksheet has the auditor admin section before beginning meter training for this reason. The 1987 checksheet has admin near the end, which is where it was in the old days and which is probably better. I would suggest doing the expertise drills later rather than moving the admin section earlier.

Although it wasn't written up in a formal fashion, the idea of doing TRs using a meter and auditor admin goes way back and was common practice for HGC auditors in the 1960s.

Oddly enough, the e-meter course does not mention the BTB above but simply lists the drill numbers on the checksheet with no reference for what they are or how to do them (the BTB is in the 1974 class 0 pack).

These expertise drills are not on the 1987 checksheet.


The 1974 checksheet puts this section after learning the rudiments, but the 1987 checksheet has it here and I think that is the better sequence.

(TV 7) (NTV 9)

HCOB 1 OCT 63 How To Get Tone Arm Action
(usually on level 1 or 3 rather than level 0, but not a bad idea to have it here)
(TV 5) (NTV 7)

I would warn that the Comm Cycle Additives bulletin originally came out in 1965 when auditors talked a lot and remind the student that maintaining 2 way communication with the PC is a point of the auditor's code and is senior.

The 30 APR 71 "Auditing Comm Cycle" bulletin references HCOB 26 APR 71 "TRs and Cognitions" which should probably also be on the course at this point. (TV 7) (NTV 9)

Note that the basic auditing series was mostly reissues of earlier bulletins (as noted) or excepts from the various comm cycle tapes (above).

Older level zero checksheets usually had: HCOB 10 DEC 64 Listen Style Auditing And this is on the 1987 checksheet (TV 7) (NTV 9)

The older checksheets always had the Itsa Maker Line tape listed in the essentials series above. This was considered one of the most important of the level zero tapes but it slipped off of the checksheet because everybody was doing the essentials tapes first for a brief time period. Most of the other essentials tapes were on that big 1967 checksheet and it might not be a bad idea to include at least some of them.

Also, the 11 DEC 64 Scientology Zero Processes which is at the end of the checksheet should also be studied here for the theory in the opening section.

The 1987 checksheet also includes HCOB 7 AUG 59 "The handling of communication processes, some rapid data" (TV 3) (NTV 5)

Even with all this, the class zero course has always been deficient as to why the processes work and what you are really doing. It seemed a bit magical to me back in 1966. The underlying theory goes back to early 1950s material on flows and ridges and I didn't really have a good feel for the level until I heard some of the older tapes. The 1952 tapes in T88 or the PDC probably introduce too many other things, so a slightly later tape on communication specifically (maybe one of those in the 3rd ACC) might be best here.
