No time during the On-site Training visit should be wasted, and this includes lunch! :-)
Lunch should be spent with the On-site Trainer in discussion with the Church Project Manager, SPoCs, and any Leadership or Pastoral Staff who are there and want to join the table. Other attendees at training should not be present. If the church is providing lunch for everyone, this group of people should be at a table by themselves. If everyone is on their own for getting food, then this group of people should go out together. The purpose is two-fold: for the trainer to provide feedback on what they see from the front of the room, and for the others at the table to provide feedback on what they see from the learner's perspective (is the trainer talking too fast? too slow? etc.)
If time permits the balance of the lunch break can either be focused on those students who are just ‘more needy’ than others, or a free for all. Remember, though, this is not a consulting session. The trainer can provide their personal opinions that are based on their own experiences, but they cannot answer (and should not be asked) to give formal guidance on what your organization 'should do' in this or that situation.
A note about the lunch itself: if provided, please make them as healthy as possible. If sending people to get their own, please encourage them to make it healthy. Carb-loading (aka - pasta, breads, pizza) during a lunch where people are expected to go back to a darkened room and sit in a chair for two hours listening to someone teach them about software is a recipe for disaster. Fresh vegetables, salads, healthy fats, and significant sources of protein are helpful in keeping everyone alert and awake during those important afternoon sessions. Remember - *half* of your classes are in the afternoon! You want to set folks up for success and that means staying awake in those afternoon hours :-)
With regard to snacks - as tempting and 'fun' as it is to provide a constant supply of candy on the tables or at each seat, please resist the temptation. Sugar crashes occur roughly 20-30 minutes after snacking on candy and other processed-sugar-laden treats - this is right when the light bulbs should be going on! If treats are desired (who doesn't enjoy treats?), try to moderate it with seeds, nuts, and other more natural alternatives. Of course, we're not the food police, so you do what works for your culture. We just want you to gain as much from the on-site training as possible and, based on our experience over almost a decade, these tips will help.
