IICRC

The IICRC standards serve to develop common, industry-accepted language and terminology that will lead to a higher level of competency for workers in their respective fields. IICRC-certified technicians set themselves apart through training, experience and comprehensive examinations.
The examinations consist of the successful completion of one or more of the 28 certification courses available. The exams are based off standards set by the IICRC, which is an American National Standards Institute (ANSI) member and an accredited standards developer.
When you hear the term “industry standard,” it means a standard of function or operation that is carried out in that respective industry. The IICRC standards are upheld to the highest globally recognized standard in which all IICRC technicians and firms govern themselves by the quality and assurance they provide to the consumer.
