Certification for the janitor or building cleaner professions is available through the Building Service Contractors Association International, the IEHA, the ISSA Worldwide Industry Cleaning Association among other associations, according the U.S. Department of Labor's Bureau of Labor Statistics.
To obtain janitor certification, an applicant must complete one of the various certification programs. While the requirements differ for each program, they often include completing online courses and participating in on-sight inspection. Completion of a certification program typically is achieved upon passing an examination or completing on-site assessments specific to the given program an applicant chooses.
Certifications for janitorial positions vary in designation, as the IEHA website states. The Certified Executive Housekeeper and Registered Executive Housekeeper certifications are just two of the IEHA's designations, each of which are similar to an associate degree. For these programs, status must be renewed on an ongoing basis. The IEHA also offers a master's program, which requires additional credentials. The Building Service Contractors Association and the ISSA Worldwide Industry Cleaning Association both offer programs similar in nature to those of the IEHA.
Janitor certification, while appealing to potential employers, is not required by United States law to pursue a career as a janitor or building cleaner.
