A professional certificate is an earned credential explaining that the named holder possesses certain knowledge and/or specific skills. While they can be issued internally by companies to their employees or tied to certain products (such as IT certifications), the processional certificates indicated here are recognized across an entire professional field. They often require job experience, additional education, and testing requirements. In short, when individuals see that you have a certificate, they understand that you know how to do a specific job.
Because certifications are intended to remain unconnected to any individual employers, it is important to select a well-respected credentialing organization. NREPSM is recognized by multiple government agencies, branches of the military, and state governments.
