The ACI-SC Certification Program for Concrete Field Technicians – Grade 1 was developed for the purpose of certifying concrete technicians who will be qualified to conduct field tests on fresh concrete. The program is expected to upgrade the quality of concrete construction and prepare the industry for possible future mandatory certification and form the basis for higher-level of certification programs.



The ACI-SC Certificate is valid for a period of five years and will be awarded to an individual who has demonstrated knowledge in concrete testing by successfully passing both Written and Practical Examinations. The concrete field technician must demonstrate ability to correctly perform and record results of the field tests on fresh concrete.


  1. If the technician’s original certification has expired at the day for a scheduled Re-Certification Examination, then the technician must attend the entire training course as a new Certification and pass both the Written and the Performance examinations to become Re-Certified.
  2. Before certification has expired, if the technician passes the Written examination on the first attempt, Re-Certification is granted. If the technician fails the Written examination on his first attempt, then he/she must attend the entire training course as a new Certification and pass both the Written and the Performance examinations to become Re-Certified.

(Note: A copy of the original certificate shall be submitted to ACI-SC Education Committee during registration for verification).



If the technician fails in either Theory or Practical examination then he will be eligible to sit for a Re-Sit examination. However, if he fails the Re-Sit examination on the first attempt then he shall not be eligible for any more Re-Sit examination. The technician must enroll for the training course as a new Certification and pass both the Written and the Performance examinations to become Certified.

  • To assure that qualified technicians perform testing for fresh concrete properly.
  • To help the technicians gain more self-confidence on the job, and ultimately, instill greater
    confidence in the entire construction team and the general public as well.

Note: The performance tests & material specifications shall be based on SS BS EN and BS EN standards.
