If you are like me, you buy a bunch of .10 notebooks before each school year. I have about 5 spiral notebooks at each building and just grab one on my way to meetings. The problem is I don't have 1 notebook for RtI, 1 for CSE, 1 for staff meetings and so on so all of the information is mixed together. To find notes, I would have to look through 10 notebooks.
Remember, organization is about being efficient with your time and this is definitely not an efficient system. This is a simple fix that you can choose to do mid-year or start when the new school year begins. Gather your notebooks - new or used. Rip out the used pages if you are starting with used notebooks. Put the empty notebooks on your shelf. The next meeting you go to - grab a notebook and label it. Continue to do this every time you need a notebook - as long as it is an event/meeting that will reoccur.
Here are some times when I use notebooks:
Principal Discussions (observations, concerns, anything where you meet 1 on 1 with the principal)
Professional Development Workshops
Congruence with Teachers
