Rectification Basics

6 Class Meetings
Prerequisites: Basic knowledge of natal astrology, transits, solar arcs, and progressions.

Course Description:

Rectification of the birth time is the technique to determine the correct birth time based on the astrological events affecting the native's chart that are associated with significant life events in the past. The ability to rectify the birth time is a requirement for certification with NCGR and other astrological organizations and a very helpful tool in consulting work with clients.

This course ($213 for 6 class meetings) is audit only (no homework, no final exam, no credit). If you are IAA Diploma Program students and need a credit, please register under "Professional Training" module: https://www.astrocollege.org/academic/course.cgi?COURSE_CODE=1558196058-2265987


Class Meeting 1: Basics

Introduction to rectificationIt’s more time-consuming than difficult. Bonus! Doing rectifications can teach you a lot about astrology.It’s not an exact science. Be frank about that.What rectification has in common with being a lifeguard . . .Helping clients find their birth time if possibleThe time frame: the narrower, the better. It’s best if they know the birth time within six hours, * with some exceptions If all they don’t know is whether it was AM or PM If the Moon changed signs that day, you might be able to go ahead “tie-breaking questions” for Moon signs or Ascendant signsUsing transits, solar arcs, and the progressed Moon: three techniques for cross-checking. Collecting meaningful life events and their dates from the client without “leading the witness.”* as accurately as possible.* asking for photos at as many different ages as possible.* the vital importance of confidentiality!* it’s what’s meaningful *to the client,* and in what way, not what’s meaningful to youDrawing the blank degrees-and-modes diagramFourth harmonic aspectsRun charts for the time frame’s beginning & end, and for several intervals in betweenWorking with the client’s list of dates and events * Asking for clarification if necessary * What transiting planets’ positions to notate *on their double-spaced list of events,* If the client knows only the year, or season, or month, or week of the eventColor-coding the events by types: at least by Asc/Desc. events, MC/IC events, and geographic moves. color-coding other types of event is optional.Filling out the degrees and modes diagram (the DAM, for short) Color-coding the events only by Asc-Desc related and MC-IC-related on the DAM

Class Meeting 2: Ascendant, MC, and Solar Arcs

What events did you include, and why?What needed clarifying?Did you color-code anything but Asc/Desc, MC/IC, and changes of address?We’ll fill out the DAM and color-code it in class. What to write down on the DAM first!Tips for the absent-minded or those who might lose their place on the list or the DAMKeep everything you do & all client communications with the client’s rectified chartLook for a *relationship* between the Ascendant and the MC, not just for the Asc.The MC moves at a certain number of degrees per a certain number of minutes (in most house systems). The Ascendant does not. The importance of the ruler(s) of the Ascendant.Using solar arcs for preliminary fine-tuning.

Class Meeting 3: Progressed Moon

Review what the solar arcs may have shown you. As many as possible should “fit.”Using the progressed Moon for more fine-tuning.The rectified chart should fit as many details as possible.

Class Meeting 4: Solar Arcs

We’ll discuss solar arcs for this chart in class. Q and A

Class Meeting 5: Practice

We’ll discuss the progressed Moon timing related to this chart. We’ll start another rectification in class, partly to see what you want to review for the final.What would you like to review for the final? Please come to the next class prepared with any questions or comments, or email them to me.

Class Meeting 6: Review and practice

Review, with practice test. Concluding remarksAny more Q and A
