We schedule a Tuesday morning meeting (during an existing Bible study which several teachers already attend, including me.) We have about 10 attend.
We also schedule an evening meeting for the same day. 6 attend that one (3 of us from the morning plus teachers who couldn't make the morning meeting).
It's frustrating when people miss the training, but then, isn't getting adults to attend always kind of like that? And this is one of the reasons we "rotate" -- so they can learn from their first week's lesson (and mistakes) and do the lesson better for the next week's kids.
With my lessons, I usually include an overview of all the classes and background information (what I find on this site is usually a good adult lesson). I have been trying to include a Teachers FAQs as well, a sample is below: I am always available the first Sunday of a rotation, but have yet had anyone w/ free time for “a quick prayer and Q/A meeting”.
The first Sunday of a new rotation we also hold a teacher's meeting for a quick prayer and Q/A.
