I maintain a stock of the survival supplies and equipment that we use for training, so the boys do not pull their kits out too often. And I do have them practice skills they have learned often, just to reinforce the learning. I also spot check them on occasion just to know what I am dealing with and where the gaps may be. I do this with first aid kits, ten essentials, and other camping gear also. I admonish the scout for "not being prepared" and then I let their parent know. This usually gets the deficiency filled.
