1. Make the decision as local as possible.
The point of the program, as it seems to me, is to allow local leaders to choose, through inspiration and/or discernment, from the 30+ talks from general Conference based on the needs of the people receiving the lessons. It makes sense for those closest to the students to make that decision and/or receive that inspiration. As a rule, the chance for inspired decision-making should be passed as far down the line as possible, especially in terms of administration rather than doctrine. From the guidelines for Teachings for Our Times: ‘Stake and district presidents may choose which talks should be used, or they may assign this responsibility to bishops and branch presidents.’ I would encourage passing the responsibility along unless spiritual discernment suggests otherwise.
