I created this log to use in my upper elementary self-contained SPED class. The log allows for six changes/checks per day with time, change of clothes, and initial fields. These logs can be customized with the student's name and the weekly date.
I place these in a large book in the changing room - one for each student. At the end of the week, I file them in a filing cabinet. This provides quick access if I need to look for patterns in toileting habits (not wetting enough, etc.)
