Do you need a way to keep track of calls to or from parents? I keep a log by my phone. It is on a clipboard by my office phone. Every time I make a call to a parent or a parent calls me, I make a log of it. Just a good way to look back over the school year of my communication with parents.
My teachers also have a call log. This call log is located in their teacher binder. They create one for each student and then turn the class set in at the end of the school year.
If I could give teachers and principals advice, it would be to keep good documentation and be organized with it. One of the best things anyone could do is to keep good records. Keep written correspondence to parents and staff on file so you can refer back to it at a later date.
