ISSA Clean Standards

ISSA Clean Standards2024-06-28T20:05:20-05:00

Objectively assess your cleaning processes

The ISSA family of Clean Standards establishes a framework to help schools and other institutional facilities objectively assess the effectiveness of their cleaning processes using ATP meters in conjunction with a more traditional audit process. Based on the philosophy of “Clean, Measure, Monitor,” the ISSA Clean Standards contribute to the quality of the indoor environment by focusing on:

  • The desired levels of cleanliness that can reasonably be achieved
  • Recommended monitoring and inspection procedures to measure the effectiveness of cleaning
  • How to use the measurement and inspection results to assess and improve cleaning processes and products, ultimately resulting in a clean, healthy, and safe indoor environment.

The ISSA Clean Standard: K-12 Schools establishes a framework to help schools objectively assess the effectiveness of the cleaning process at their facilities, thereby contributing to the quality of the indoor environment for the benefit of students and staff. Based on the philosophy of “Clean, Measure, Monitor” and an emphasis on high-performance cleaning, the Clean Standard: K-12 focuses on:

  • The desired levels of cleanliness that can reasonably be achieved;
  • Recommended monitoring and inspection procedures to measure the effectiveness of cleaning;
  • How to use the measurement and inspection results to assess and improve cleaning processes and products, ultimately resulting in a clean, healthy and safe learning environment.
How exactly does The ISSA Clean Standard: K-12 measure the effectiveness of cleaning?2024-01-30T18:20:44-06:00

The ISSA Clean Standard: K-12 contains both objective and subjective components. The Standard specifically provides “ranges of clean” based on ATP testing as well as sample audit forms. The inclusion of ATP limits adds a quantitative to the determination, while the audits assist with a traditional “sight, smell, and touch” perspective. The ultimate goal is to ensure that schools are in a condition that is clean, safe and healthy for students and staff.

To whom does The ISSA Clean Standard: K-12 apply?2024-01-30T18:24:02-06:00

The ISSA Clean Standard: K-12 specifically applies to schools, providing them with a key tool to measure and monitor the cleanliness of their facilities. That said, the Standard serves as a valuable sales and operations tool for distributors, manufacturers, other industry suppliers, and building service contractors.

As we seek to “change the way the world views cleaning” and demonstrate the true value of clean, the Standard serves as a powerful resource that can assist in the sales process, help schools operate more efficiently and, ultimately, demonstrate that cleaning is properly treated as an investment in health, safety, the environment and the bottom line.

How does it interact with other industry standards?2024-01-30T18:41:28-06:00

The ISSA Clean Standard: K-12 complements existing industry standards. By setting forth a process and protocol for measurement and monitoring, the Standard naturally works in concert with other industry standards, including the Cleaning Industry Management Standard (CIMS) and CIMS-Green Building program, existing “green” product standards, and individual training criteria, to offer schools a comprehensive road map for effective management and operations and the delivery of healthy, clean indoor environments.

Does the Standard recommend products, procedures, and systems?2024-01-30T18:42:50-06:00

No. ISSA continues to cherish the diversity that is woven into the fabric of our industry. The Standard, therefore, is “non-prescriptive” and its goal is to act simply as a measurement and monitoring framework. While the Clean Standard: K-12 does provide ATP measurement ranges for three of the most popular ATP systems, the Standard should not be construed as endorsing any of the three referenced systems. Ultimately, each school retains the flexibility to choose how it can best meet the Standard’s requirements and are free to select manufacturers, distributors, products, and educational tools that best assist them in achieving compliance.

How is the Standard administered?2024-01-30T18:44:17-06:00

The Clean Standard: K-12 is administered by ISSA. ISSA, a not-for-profit association founded in 1923, prides itself on being the leading association for the cleaning industry worldwide. ISSA administration ensures that there is no commercial bias to any group.

How was the Standard developed?2024-01-30T18:45:57-06:00

The ISSA Clean Standard: K-12 was developed through a true consensus-based process. Experts, representing all sectors of the industry, including the facility management and school communities, were selected by the ISSA Board, staff, and alliance partners to participate on standard development and stakeholder Committees. The committees worked directly with ISSA and its partner, the Cleaning Industry Research Institute (CIRI) to draft the Standard, which was subject to full peer review prior to official publication.

What was ISSA’s role in developing the Standard?2024-01-30T18:49:42-06:00

ISSA provided organizational oversight by leveraging its unique role in the industry. ISSA’s diverse membership is comprised of:

  • Manufacturers
  • Distributors
  • Manufacturer Representatives
  • Facility Service Providers
  • Industry Consultants
  • School Community Representatives

The shared interests of its membership base enabled ISSA to provide the necessary oversight. In addition, the many alliances that ISSA has developed with leading organizations in the cleaning industry and school communities lent valuable insight to ensure a balanced and comprehensive approach.

I hear the Standard is based on “science” and comprehensive research? What does that mean and what was the process?2024-01-30T18:51:57-06:00

The ISSA Clean Standard: K-12 is specifically intended to provide scientific validation of cleaning effectiveness. That said, the development process by guided by independent and unbiased scientific research conducted by the CIRI “Science Advisory Panel”. The research included thousands of ATP measurements from high touch surfaces recognized as posing health risks in schools (i.e.: student desks, cafeteria tables, restroom sinks and stall doors). The ATP measurements were conducted in numerous schools across the United States to account for potential geographic or climatic variations

The details of the research are set forth in “ATP as a Marker for Surface Contamination of Biological Origin in Schools and as a Potential Approach to the Measurement of Cleaning Effectiveness,” as published in the June 2013 issue of Journal of Occupational and Environmental Hygiene by Shaughnessy and Cole, Each school selected its own cleaning method which was then rigorously monitored for compliance by research personnel. Following cleaning, sampling procedures were conducted on the cleaned surface.

What does the Standard consist of?2024-01-30T18:53:19-06:00

The ISSA Clean Standard: K-12 is focused on achieving and maintaining an effective cleaning program through the use of a systematic approach and standardized guidelines centered on the following:

  1. Defining Current Cleaning Procedures
  2. Identification of High Touch Points
  3. Facility Audits
  4. ATP Testing Protocol
  5. ATP Measurement Evaluation
  6. Establishment and Implementation of Corrective Action
  7. Recordkeeping
  8. Technical Training
  9. ATP-Relative Light Unit Limits
  10. Alternative Methodologies
What are “Alternative Methodologies” as included in the Standard?2024-01-30T18:56:46-06:00

While the ISSA Clean Standard: K-12 is based on the use of ATP measurement, there are a number alternative methods that are capable of objectively validating the effectiveness of a school’s cleaning processes. These methods include direct practice observation, the use of fluorescent markers and others and are specifically referenced in the Standard.

Does complying with the Standard ensure that a facility is healthy?2024-01-30T19:50:00-06:00

While ATP meters have been validated as the preferred quantitative method of determining cleaning effectiveness, their use does have certain limitations. That said, achieving ATP measurement readings that fall in the “Effective Cleaning” category does not ensure that the facility is absolutely free of contamination or represents a completely healthy facility.

However, research has noted a reasonable correlation between ATP reduction and healthier indoor environments. Concurrent with ATP testing, the researchers tested surfaces for culturable bacteria using a different method – RODAC plates. The simultaneous testing demonstrated that a reduction in ATP was accompanied by a consistent reduction in bacteria. The researchers, therefore, were able to reasonably conclude that a reduction in ATP suggests both a cleaner and healthier surfaces.
