Certification is one of the best ways to show employers, clients, and colleagues that you have the knowledge and skills to meet the industry's standards. Professional certification is a process in which a person proves that he or she has the knowledge, experience, and skills to perform a specific job. Professional certification shows employers and clients that you are committed to your profession and are well trained. It gives them confidence in your abilities. The main thing to keep in mind is that if your job requires certification on a specific tool or technology, or if gaining that certification will help your resume stand out, it's smart to invest time and money to achieve it.
