I will see if I can find a copy of one of our officer task booklets. We have levels 1 for entry firefighters to level 4 for master firefighters. We don't have one really for engineers because each apparatus category has a task booklet for them and then also the officer task booklet.
Mentoring is and has always been an important part in the fire service whether it is verbal or written. It takes time and effort but will pay huuge dividdnds to the individuals and to the department in the future if it is well thought out, executed and re-evaluated over time.
Good luck, Stay safe and Merry Christmas
