GFRC Certification Examination
The GFRC exam is a closed-book examination with 50 multiple-choice questions. The examinee is allowed one hour (60 minutes) to complete the examination, and a final score of 70% is required to pass the examination.
GFRC certification is valid for a period of five years from the examination date. Recertification requires meeting all the above requirements for initial certification. Recertification requires re-examination and evidence of 36 months (total for five (5) years) of continuing acceptable experience in the production of GFRC.
Recertification with examination is required every five years until the individual has taken three exams over a 10-year period. Individuals who have passed three (3) GFRC exams over a 10-year period and have been continuously certified as GFRC Technicians for 15 years no longer have to meet the examination requirement.
Recertification without examination requires completion of a certification application and submittal of the request for exam exemption. The individual’s certification application must include evidence of acceptable continuing education and/or training every five (5) years. Continuing education or training must include one of the following:
- Pass the GFRC examination administered by proctor with a minimum grade of 70%,
- Submit evidence of fifteen (15) hours (total for five (5) years) of continuing education or training in the field of quality control; design, concrete, finishing or other topics relevant to the GFRC industry, or
- Submit evidence of 36 months, (total for five (5) years) of continuing work experience in the field of quality control, engineering or production in the GFRC industry.
Failure to recertify within ninety (90) days after the expiration date shall require re-examination to reinstate certification. Failure to recertify within six (6) months after the expiration date shall require re-examination, and the individual’s certification records will reflect a gap in certification.
