LEED AP with Operations and Maintenance (O+M ) Practice Exam

What minimum cleanliness level must a project achieve based on APPA's Custodial Staffing Guidelines?

1. 1.0

2. 2.0

3. 2.5

4. 3.0

The correct answer is: 2.5

The minimum cleanliness level that a project must achieve based on the Association of Physical Plant Administrators (APPA) Custodial Staffing Guidelines is indeed 2.5. This cleanliness standard is critical because it represents a balance between maintaining an environment that is clean and safe for occupants while also being practical in terms of staffing and operational costs. A cleanliness level of 2.5 indicates a "regular clean" setting, which is suitable for areas with moderate traffic, ensuring that spaces are comfortably maintained without the intensive labor and resources that higher levels would necessitate. This level typically ensures that surfaces are dusted, floors are vacuumed or mopped, and restrooms receive adequate attention. Lower cleanliness levels, such as 1.0 or 2.0, pertain to less rigorous cleaning standards that might be appropriate for less-used or less critical spaces, while a level of 3.0 or higher would be suited for high-traffic areas or spaces that require a more sterile environment. Thus, 2.5 is positioned as a foundational standard that encourages a practical approach to custodial management in promoting hygiene and aesthetics within a facility.
