Grades, Happy Faces, and Not so Happy Faces
It's human nature during the learning process to only do as much as you have to do to get by. This is how I handled algebra in college. But then, I knew that I was never going to be a scientist nor a mathematician, so I wasn't too worried about my strategy. The FTO program is not a college math class.
The situation you find yourself in now is a new phenomenon; nearly everything that you are to be taught in the FTO program is a real-life vocational life-long skill. Therefore, you must perform at a higher level of expectations than "just enough to get by." Now, for the first time, you have to be an over-achiever. Why? Because the butt you save now is yours, and others' lives are depending on you.
Not all of your grades are going to be "happy faces." You are just beginning to work a very demanding job—in the public eye on real cases—with very real consequences. You are not role playing now. So don't become disheartened when your FTO clamps down on you because your scores for today are not acceptable. You may need remediation training or just a good stern talking to from your training officer. Constructive criticism is like medicine: it's good for you, but it leaves an unpleasant taste in your mouth.
Nobody in the history of law enforcement has ever gone through the FTO program unscathed, so don't get your feelings hurt. You will have virtually everything explained to you, then demonstrated to you, but soon you will have to perform. What you have to remember is that most of the time you will be allowed some practice before you actually perform any task under real-life circumstances. If you do not feel comfortable, verbalize this to the FTO. Don't get out there and just bumble through a call.
