Thanks all. In EQ we recently split the group into two by birth month to reduce the lesson discussion group size, it worked fairly well at maintaining an even split. For teacher training, I found this part in the Teaching the Savior's Way manual, which probably answers my question! "Teacher council meetings should normally take place during the 50-minute class time of the two-hour schedule of Sunday meetings."
I was called as Sunday School President and am curious about how others do teacher training or manage multiple adult Sunday School classes. Do you do teacher training from the Teaching the Savior's Way? When, how often and where do you hold it? Are you holding multiple Adult Sunday school classes? How do you manage traffic or class sizes between the two, or do you allow them to self-regulate? Thoughts about what works, or doesn't, would be great!
