Certification Requirements for Concrete Flatwork Finisher & Technician

ACI will grant certification only to those applicants who obtain a passing grade on the written examination, and either a) possess one year (1500 hours) of approved work experience and successfully complete the ACI performance examination or b) possess 3 years (4500 hours) of approved work experience and successfully complete the Alternative Performance Affidavit (Form D16). The work experience must include placing, consolidation, finishing, edging, jointing, curing, and protection of concrete flatwork. Verification of the amount and range of work experience by the applicant’s employer(s) is required

The two-hour written examination is “closed book” and consists of approximately 50 multiple choice questions. The passing grade for the written examination is 70%. During the performance examination each examinee must place, consolidate, finish, edge, joint, begin curing and provide initial protection for a concrete slab. The examiner will observe and evaluate the techniques used and record passing or failing grades on the various individual procedures. A passing grade is defined as “no significant variation from proper procedure and no more than two variations from proper technique in the use of the tools.” The Alternative Performance Affidavit (Form D16) is a possible alternative to the performance examination. It requires each applicant to submit a signed affidavit(s) from current and/or previous employers verifying that the applicant’s proven abilities are equivalent to those listed in the ACI performance examination checklist. Note: Optional forms and procedures are available for self-employed finishers. Re certification is necessary every five (5) years, and requires successful completion of a written examination.
