High School

No special educational requirements exist for this position, although employers prefer to hire applicants with a high school diploma. Classes that are helpful to prospective janitorial workers include family and consumer science, mathematics, and chemistry. Because understanding and following directions is very important, English or communication classes might be beneficial. Finally, shop classes can help by teaching minor plumbing or carpentry work.

Postsecondary Training

No postsecondary training is required for janitors and cleaners. IEHA offers educational opportunities for janitors and cleaners who would like to brush up on their skills, as well as certification for those who complete specific programs.

Certification or Licensing

Although not a requirement for finding a job, some janitors opt to become certified by IEHA, which offers several levels of certification or programs that indicate a certain degree of professionalism and training and may be beneficial in finding a job or in moving to better positions. Certified Environmental Services Specialist Program is designed specifically for frontline workers, including EVS specialist/technicians, housekeepers, custodians, housekeeper porters, and janitors. The Certified Environmental Services Executive (CESE) designation requires the completion of 16 modules within IEHA's Professional Education Credentialing Program (PECP). The Registered Environmental Services Executive (RESE) designation requires completing five modules in the PECP's Managing for Effect Series and 11 modules within IEHA's Technical and Administrative Series. Finally, the Master's Program is offered for "elite members committed to continuous improvement and propagating professionalism." These certifications must be renewed every two years.

Other Requirements

Custodians may be required to be able to lift objects up to or exceeding 50 pounds.

No previous experience is usually necessary to obtain an entry-level janitorial job. However, some employers, especially if providing service to executives or in prominent facilities, may look for workers that have at least two to three years of experience. This is also the number of years most employers look for in someone they are considering for a supervisory position.

In addition to being physically sound and able to stand for long periods, these workers should be able to lift heavy objects, be familiar with a variety of cleaning tools and equipment, and have mechanical ability or aptitude. Other good traits for janitors include stamina and interpersonal skills.

When it comes to personality traits, a strong work ethic and eye for detail can be beneficial. Janitors should have a certain level of stamina and energy, since the job does require physical labor. Finally, tact and courtesy in dealing with people are important assets. Employers usually look for dependable, hardworking individuals who are in good health, follow directions well, and get along with other people.
