Industry certification programs are similar to licensing programs but are voluntary. A license is essentially the state s certification that you are qualified to practice your profession.

Certification programs are a voluntary way to show that you have met the knowledge, skills, and professional ethics requirements of the certifying agency.

Obtaining a certification gives employers and clients the assurance that you know what you are doing.

In addition, since certification programs are voluntary, they indicate that you have made a commitment to maintaining and improving your professional knowledge and skills. Here is a list of popular certifications:
