Any advice to help prepare for Army Basic Instructor Course or Small Group Instructor Training?

I used pre-made classes I took from our courses. I had to add the mandatory slides they wanted and then I just rehearsed it.

Don't sweat it. You'll be fine. Once you get there and see how much of a breeze it is, you'll laugh at yourself for worrying any at all.

If you're looking for atta boys, after your safety stuff etc hit for 5 minutes or so on OE. Usually NCOA types teach ABIC/SGITC. They love OE discussions.

Other than that, don't drink too much and bring some monsters to stay awake.

Picking a topic to instruct on is often the hardest part. Depending on the instructors, they may require you to pick military specific topics, or they may allow you to teach something nonspecific to the military. If you come with some ideas of tasks you are comfortable teaching, they will walk you through the rest. Good luck!

Learn how to develop lesson plans and outlines. Be open to criticism have fun

You might want to ask for advice.....pay attention and ask lots of questions...

Good question. In the general context, everyone is right. But, in my opinion, liaison duties are not taken into account when training different units. Learning in small groups on different topics is good; it is easier to prepare for a small group than for a large one (if they are units of different directions with one main and several secondary tasks). But it also depends on interest and the form of information submission. It takes a lot of effort to create a good methodology for training multiple groups in a particular direction of interaction. When one group understands the tasks of neighboring groups (when performing certain tasks), interaction between units must be worked out, because the goal is the same - the protection and integrity of the unit.

Why are you going to those classes and not to CFD-IC? I thought ABIC was phased out.
