These two overlap but are separate at times. I've seen far too many who possess superior knowledge, skill, and ability as a police officer. Yet, they aren't able to convey them to a recruit. I've often stated that I did not need a FTO who had superior police skills. I prefer one with great instructional skills. I know you know your job, but can you pass it on to others? Teaching can be a perishable skill, so you've got to practice.
Now, back to the question. The downsizing or budget cuts haven't allowed the department to hire any new recruits, so how do you stay sharp as an FTO?
There are several outlets for an FTO to practice his or her skill set. Some may not seem the most exciting, but we're not after thrills. We want to keep the mind sharp by providing a workout for the instructional part of the brain.
If the FTO is not an academy instructor, apply for instructor school. Learn lesson-plan development, and enhance your presentation skills. If you're already an instructor, pick up the pace! Offer to teach at the police academy more than the norm. Getting in front of a class of recruits will keep you in touch with the new generation's mindset and needs. Reach out to the criminal justice department at your local college and give a guest lecture.
FTOs make great interdepartmental instructors; most of the staff are your former students anyway. Offer to assist on the range, teach first aid/CPR, or review new policies or law updates.
