Although there are many restaurants out there that utilize certified Chefs, it is still something that many Chefs do for personal growth.
The competitions help teach a multitude of useful skills that one can use to enrich their careers but.....again....I maintain that the ACF is not for everybody. This is something that is dependent on what you wish to achieve in your career.
Kuan asked you how many people you supervise for a reason.
ACF is all about sharing and networking with Chefs to help improve themselves. If you have a crew, it might be all about helping THEM to achieve better knowledge and understanding of our industry and to that end, you might become a mentor to them.
It's all about what YOU want...
You need to supervise a minimum number of employees in order to qualify for different levels of certification. I think 10 people would qualify for CEC. If you can afford them go ahead and take the exams. Your local ACF chapter will probably have a schedule for the practicals. There's no harm in talking to your local chapter.
