Three levels of certification are available:
I. A Pervious Concrete Technician is a person who demonstrated knowledge by successful completion of a written exam about proper procedures to place, compact, finish, edge, joint, cure and protect pervious concrete pavements, but who lacks the requisite field experience to qualify as a pervious concrete Installer or Craftsman.
The Technician level is intended for contractor and non-contractor personnel in learning the proper techniques of installing pervious concrete. It is assumed that contractor personnel who are certified as technicians will be supervised by an individual with a higher level of certification and they will upgrade to the higher levels when they achieve the work experience criteria for Installer and Craftsman levels to qualify to install pervious without supervision. This level is also intended for any non-contractor persons such as ready mixed concrete personnel, testing labs, inspectors, admixture personnel, specifiers and engineers that need to understand the pervious concrete system. This certification level is also recommended for individuals who are knowledgeable about pervious concrete who intend to participate in training programs for local sponsoring groups.
II. A Pervious Concrete Installer is a person who has demonstrated the ability to place, compact, finish, edge, joint, cure and protect pervious concrete pavements and has documented a limited project-based field experience in placing pervious concrete.
The Installer level is intended for contractor personnel who have achieved this intermediate level of certification by completing installation of work as indicated by the certification criteria. Installers are expected to assume leadership roles when installing pervious concrete and make decisions on placement conditions and procedures. It is anticipated that contractor personnel will upgrade to Craftsman level when they achieve the work experience criteria for that level.
III. A Pervious Concrete Craftsman is a person who has demonstrated the ability to place, compact, finish, edge, joint, cure and protect pervious concrete pavements and has documented a higher level of field time-based experience in placing pervious concrete.
The Craftsman level is intended for contractor personnel who have achieved this highest level of certification by completing the work experience as indicated by the certification criteria. Craftsman are expected to lead an installing crew, work with the concrete supplier to ensure the mixture is appropriate for the installation, designate duties and assignments to the crew, evaluate site and placement conditions and make decisions when the pour needs to be stopped or re-scheduled.
After NRMCA assesses your application, you will be sent a letter confirming your status.

Exam Information
The two-hour written examination is "closed book," consisting of approximately 60 multiple-choice questions. The passing grade for the written examination is 75%.
During the performance evaluation, each examinee must demonstrate procedures for placing, compacting, finishing, edging, jointing and beginning curing a pervious 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 project experience or work experience must include placing, consolidation, finishing, edging, jointing and curing of pervious concrete, and must be documented on the Installer Application form or the Craftsman Application and Work Experience Worksheet.
