If you have space types in your project building that don’t fall into APPA categories, you can create your own and apply weightings to them. To create a weighting (each space type has elements such as floors, horizontal surfaces, and vertical surfaces that should be prioritized and “weighted” in the audit results), determine which components of the space type you clean most frequently  and determine what percentage of time you spend cleaning each one. The percentage you come up with for each space-type component is the associated weighting. For example:  If you have a medical treatment space in your building, you might determine that you spend: 

35% of the time cleaning the horizontal surfaces 
20% cleaning floors 
20% cleaning the trash containers
15% cleaning and straightening the tables and chairs 
7% cleaning vertical surfaces
3% cleaning lighting and light fixtures. 

To see how these and other weightings are used to calculate audit scores, see the Medical Treatment Room Audit Form in the APPA Audit Form workbook in the Documentation Toolkit. This template allows and encourages you to set your own weightings for spaces in your building.
