  • TBD

Course description

The Council-certified Structural Drying Remediator (CSDR) and the Council-certified Structural Drying Supervisor (CSDS) perform water damage restoration services.  For example, a CSDR or CSDS can safely mitigate water losses resulting from floods, fires, hurricanes and other disasters as well as broken pipes and water mains.  These professionals have verified knowledge of the principles, techniques, equipment and regulations relevant to structural drying as described in widely published industry texts and accredited standards. 

CSDRs and CSDCs possess verified field experience conducting structural drying projects in one or more of the following settings:

  • Single and multi-family residences
  • Offices and commercial buildings
  • Industrial structures
  • Government facilities
  • Schools and public buildings
  • Healthcare facilities


To earn the Council-certified Structural Drying Remediator (CSDR) or Council-certified Structural Drying Supervisor (CSDS) designations, the candidate must:

  • Demonstrate verifiable field experience in structural drying. (two years for a CSDR candidate; eight years for a CSDS candidate)
  • Pass a rigorous examination based on broad industry knowledge rather than a course curriculum
  • Earn the unanimous approval of the CSDR or CSDS certification board
  • Re-certify every two years
  • Participate in 20 hours of professional development activities each year
  • Maintain the highest ethical standards

The CSDR and CSDS certifications are pending accreditation by the Council for Engineering and Scientific Specialty Boards (CESB), a nationally recognized independent accreditation body.  ACAC certifications are the ONLY designations in the water damage restoration field to apply for CESB accreditation.


The Required Body of Knowledge:

The effective practice of structural drying requires knowledge of a variety of subjects related to the building sciences. For certification purposes, the candidate for the CSDR designation must demonstrate familiarity with the basic concepts and reference materials of the industry, such as those summarized in the following list.

ACAC CSDR / CSDS Preparatory Course

The RLI offers what is usually a one-day event that follows one of the IICRC restorative drying courses listed above, (WRT, ASD, CDS) this education opportunity is unique. The instructor of this course:

  • Is NOT “approved” or screened by the ACAC
  • Does NOT know what the exam questions are
  • Does NOT proctor the exam
  • Does NOT participate in any revenue received by the certification organization (ACAC)


Further, the student is not required to sit in a class in order to challenge the exam. If the student feels prepared to challenge the exam, they may do so without any tuition whatsoever.


As a result of complying with these (and other) criteria, the CESB approves qualified students as being “certified”. (Compared to other organizations offering “certificate courses”)


The RLI’s ACAC CSDR / CSDS Preparatory Course is therefore a loosely structured event that encourages open dialogue between instructor and student(s) and explore many of the commonly accepted theories promoted within the restorative drying industry worthy of re-consideration. This candid and relaxed dialogue lends to frank discussions that bring logic and scientifically sound explanations to the restorative drying professional’s strategic planning skills. This is truly a nice polishing touch to compliment an IICRC certificate course.


ACAC Certified individuals can market their educational accomplishment with the following language:



 [Certificant Name] Holds Accredited ACAC Certification


The American Council for Accredited Certification (ACAC) is pleased to announce that its Council-certified Structural Drying Supervisor (CSDS) designation has been accredited by the Council for Engineering and Scientific Specialty Boards (CESB).


The CSDS is now recognized by CESB as an engineering technician designation until 2012.


CESB is a nationally recognized, independent accreditation body founded in 1991 to provide standards for engineering-related certification programs. CESB-accredited programs must follow strict guidelines for integrity and independence in their policies and operations. CESB accreditation is a mark of superior quality and distinguishes well known certification marks such as the Certified Industrial Hygienist (CIH), Certified Safety Professional (CSP), and Certified Hazardous Materials Manager (CHMM).


The ACAC is the only indoor air quality organization whose certifications have achieved CESB accreditation. Council programs employ psychometrically rated examinations that test industry knowledge and also require verified field experience of each certification candidate. Council certifications are board-awarded by a nationwide panel of industry peers for a period of two years, after which each certificant must undergo a rigorous re-certification process.


CESB accreditation is the latest evidence that ACAC certifications continue to set the standard in the industry for integrity, credibility and independence.
