A long time ago when I conducted a study with someone there was a form I filled out- not sure if this is the one you are asking about but I filled in my students name, the book we were studying, the number of times we had the study that month and what month it was. There was a space to put in some notes. I put my name on it as the conductor of course. It got handed in with my fs report. On the fs report you wrote the number of bible studys you had, so I wrote down 1 which was for her! You needed to have the study 3 or more times every month to be able to count it. You filled out that form for each BS you were conducting. ( She never became a jw!)
Is this the form you are asking about? This was around 25 years ago- I do not know if they still use it.
