Professional Certification Exams

Professional certifications are offered in many industries to demonstrate competence in particular fields of expertise. Certification may be a means of qualifying an individual for employment or higher pay grade within a profession. The NCWM Professional Certification Program provides confidence that an individual has a strong understanding of U.S weights and measures standards as adopted by NCWM and published in NIST Handbooks, 44, 130, and 133.

Professional Certification is for a period of 5 years from the date that an applicant successfully completes an exam.  Certification is available to members and non-members in the private sector and in government positions.

As of September 1, 2018, all NCWM exams are proctored.  The online testing service will require that an approved proctor be physically present at the testing location to log in with the applicant.
