METHODOLOGY
Elliott Affiliates conducted inspections and observations of the school, including ATP tests. These
included a variety of room-types (as noted above) and item-types (such as desks, windows, door
handles, sinks) in the sample. In-process testing included speed and ease of use compared to other
cleaning methods, as well as efficacy.
In addition an attribute-based observation of random samples of all items subject to cleaning defined
the appearance performance metric. Our staff inspected randomly selected items and areas throughout
each designated room within the selected building. The sampling of buildings, room types, and items
provides information on cleaning process trends, which is used to drive process improvement for
cleaning activities.
Inspections, observations and measures were performed during normal school hours (7:30 am to
4:00pm), within the normal 5-day work week (Monday thru Friday) excluding weekends and holidays.
Testing protocol and measures in each case were as follows:
1. To monitor appearance , direct observation was taken in the testing area.
2. For organic load , Hygenia SystemSure II ATP devices and swabs were used to measure the
RLU (Reflective Light Units), following device instructions in each of the 3 testing sections. An
approximately 4”x4” square area was swabbed on the floor.
The presence of ATP (adenosine triphosphate) on a surface indicates the presence of
contamination, such as food residue, allergens, and/or bacteria, implying a potential for
the surface to harbor and support bacterial growth. Therefore, low ATP levels are
desirable. The manufacturer notes that ATP levels of 0-30 are acceptable on food
preparation surfaces, and levels below 100 are considered “clean”.
