The ninety (90) minute written examination is "closed book" and consists of 60 - 90 multiple choice questions. A minimum score of 75% is required to pass the written examination.

The performance examination is "closed book" and requires actual demonstration of your knowledge of surface preparation, equipment, start-up procedures, proper placing / nozzling technique, finishing, and curing. The examinee must place dry-mix shotcrete in the vertical position and has the option to also place dry-mix shotcrete in the overhead position.

Recertification is necessary every five (5) years, and requires successful completion of both an oral interview and performance examination(s).
