Why Choose ISSA’s Cleaning Industry Management Standard (CIMS)

ISSA has merged elements of the GBAC STAR Service accreditation criteria into the ISSA Cleaning Industry Management Standard (CIMS). This program is based on the successful CIMS criteria, which outlines the primary characteristics of a successful, quality cleaning organization, plus a renewed emphasis on maintaining hygienic environments through GBAC’s industry-leading cleaning, disinfection, and infection prevention protocols.

The result: CIMS Advanced by GBAC, one comprehensive certification for quality-driven building service contractors and in-house cleaning organizations that strive to maintain hygienic environments for the benefit of building occupants.

The rigorous evaluation and tools made available are a good combination to be successful. It is not a simple or easy certification to accomplish thus it is meaningful.”
