When people are looking to hire professionals (as consultants or FTE), they usually review the individual's educational background and work experience. Another key factor may be any certifications that may be offered in the profession. The gold standard for ergonomic certification is the Certified Professional Ergonomist (CPE) designation, provided by the Board of Certification in Professional Ergonomics.
Adding to the value of this designation, is the fact that the BCPE was recently accredited by the National Commission for Certifying Agencies (NCCA) for its Certified Professional Ergonomist (CPE)/Certified Human Factors Professional (CHFP) program. Here’s the announcement http://bcpe.org/onlinenews/onlinenews.asp?i=53 .
In addition to the CPE or CHFP designation, BCPE offers as Associate level (AEP) for those who meet the educational requirements but not the experience requirements to sit the exam. Check out http://bcpe.org/certinfo/default.asp for more info on the certification process.
