The M-1 course is the Method One co-audit course, and is located on the grade chart before the Student Hat on the training side of the "bridge" (the left side of that big huge map to OT).
It is a course that must be done with a twin, as you cannot attest to completion without taking your twin to a complete product. That is why it is called a "co-audit". One could pay professional rates to recieve M-1 from an auditor, but I don't know anyone who did.
I quote from the tech (red) dictionary:
"WORDCLEARING METHOD ONE
1. by meter in session. A full assessment of many, many subjects is done. The auditor then takes each reading subject and clears the chain back to earlier words and or words in earlier subjects until he gets an F/N.) HCOB 24 Jun 71) 2. assess, take the reading items from the best read on down with Earlier Similar pull each one to F/N. Get each word you find to F/N. There can be many F/Ns per subject. End off with a win on the subject. (HCOB 30 Jun 71RB II) 3. the action taken to clean up all misundersoods in every subject one has studied. It is done by a word clearing auditor. The result of a properly done Method One word clearing is the recovery of one's education. (Aud 87 ASHO) Abbr. M1."
There are Word Clearing Methods 1 through 9. Then there are Word clearing Correction lists. There are also Word clearer courses. The grand daddy of all word clearing is the "Key to Life" course, where you pay alot of money to to M1 through M9, plus clay demo every definition of every word in a junior high level grammar book. The books for that course alone cost $5oo.00, I think the course is around 10 thousand dollars. You are advised that the "Key to Life" takes 6 monhs part time, 2 months full time. (Full time is 9 to 6 Monday through Friday).
If this is too much information, just ask me. I can tell you more
