Unfortunately, all instructors get bored teaching the same material over and over. When that happens, they’ll start teaching whatever they feel like, or their classes will get stale and repetitive.
If either of these things happens, your students will stop enjoying the training and, rather than tell you, they’ll stop showing up.
Left long enough your business will come under threat, and you’ll have to step in to fix the problems.
I should know this happened to me when I was running my full time school of 400 members. I took my eye off the ball and essentially left my instructors to it.
This mistake cost me 77 students over 6 months. Doh!!!
Since then, I’ve been a massive believer that staff training should be a priority for every school owner.
