Roll Your Own Prehav Assessment has been developed:
The assessment is done on any available or special Prehav Scale for the purpose of the assessment. (For instance the 1st 65 levels of the Auxiliary Prehave Scale.)
The assessment follows the exact steps below:
It is very easy to do a Prehav Assessment. It is not so easy to do a completely accurate one.
When clearing is going hard, the most likely source of error is the Prehav Assessment. It is ridiculously easy for an auditor to make a bad one. The Preclears attention hangs up on a button he tells himself isn't it and the invalidation makes it stay in and voila you have a wrong assessment.
Like goals, a Prehav Assessment must be kept clean of Tiger Drill buttons.
You get a wrong assessment if the pc has invalidated or protested a button. Or if he or she has suppressed the right one. Also if too many levels are staying in or too many are going out, the Mid Ruds are out.
A Prehav Assessment requires careful auditing. Only experience can give an auditor the full data.
Prehav Scale = Any scale giving degrees of doingness or not doingness.
Level = Any doingness or not doingness on the scale. Any word in the scale itself. Assessment = Any method of discovering a level on the scale for a given pc.
Read = Any reaction of the needle different from its regular action for the pc, occurring during or slightly after a level has been called.
Mid Ruds = The middle rudiments of the current model session.
Tiger Drill = That series of buttons which are capable of preventing a right goal or level from reading or making a wrong level read, combined in an appropriate exercise.
Realize that the most accurate assessment of a Prehav Scale would be by the Tiger Drilling of each level in turn.
By average, on a rough pc, this would require about one minute per level. This would be three hours for a 180 level scale.
Unless scales are shorter, assessment by elimination would normally be faster, if done with due care. But Tiger Drilling a scale to find a level cannot be ruled out as a means of finding the real level with superb accuracy.
One puts the pc in session, gets the Mid Ruds in, takes a Prehav Scale and calls out each level once, noting its reaction on the meter.
If the auditor was not sure or didn't see it, the level is called a second or a third time.
If too many levels go out consecutively, there is a suppress. If too many levels are staying in, there is another Mid Rud out.
One marks only those that read. Those that do not read are not marked.
A pc has his own Prehav Scale mimeo copy in his folder. This is used over and over. The pc's name and date of the first assessment is written at the top of the mimeo sheet.
A new symbol is used for each consecutive assessment and the level found on the mimeo sheet and that symbol is marked at the top at the end of the assessment.
The list is covered once. Those that read are marked in.
The Mid Ruds for the session are put in at the end of the first nulling.
The list is covered again but only those that stayed in the first time are now read. If they read again they are again marked in, using the same symbol.
The list is covered a third time but only those that stayed in the second time are read and marked in, using the same symbol.
When the list has not more than eight (on a rough pc) and not less than three levels left in, the remaining levels are Tiger Drilled.
One level will remain — or will react better than the others. Take this as the PRIMARY LEVEL and mark it in at the top of the mimeo sheet with its symbol.
In times past, this Primary Level would have been enough, but using the Prehav to locate the Rock Slam Channel or to list out goals requires a SECONDARY LEVEL.
To "Roll Your Own" is to get the pc to give you a secondary scale that is in its turn assessed. This is done as follows:
Take the Primary Level, found as above. Put it in the sentence "If somebody were fixated on (or 'wanted to' or 'intended to' or 'wished to') (Primary Level) what would that person do?" Or use the sentence "What would (Primary Level) represent to you?" The sentence must cause the pc to give doingness. Otherwise it must be changed, using the Primary Level, so that the pc does give doingness.
The auditor, as in any assessment, lists down the pc's answers on a 13" (foolscap or legal) sheet with the pc's name, the date and the question at the top of it.
When the pc says that's all, the auditor puts in the Mid Ruds and lists the question against the meter. If the meter reads on the question, the list is incomplete and must be completed.
When the question gives no read with Mid Ruds in, the list is complete. This list is now handled exactly as the original scale above.
The resulting level is the pc's level and is used for finding Items in 3GA-XX or in listing out goals. The Primary Level is not otherwise used.
The Secondary List is not used again. A new Primary Assessment is done for the next full operation. Only these Secondary Levels are actually used in auditing.
Various Primary Prehav Scales may from time to time be developed for various purposes.
