How long does the training process last?
A good official will tell you they are always learning so training never ends. However, the NVFOA's official training program for entry-level officials is currently a two-year program.
During their first year, the trainees focus on learning the rules of the game and the mechanics used by a 4-man crew in positioning themselves on the field and dealing with their respective areas of responsibility. The second year focuses on fine-tuning 4-man crew skills, unusual game situations, and learning the 5-man crew mechanics necessary to officiate at the varsity level.
Upon successful completion of the training program, trainees are made regular members in the NVFOA and are eligible for assignment to a varsity crew on a full time basis.
