I found that this little slip helps a lot! There were instances that teachers were so overwhelmed that they wouldn't be able to find me to talk about a student situation they were concerned about and time would pass and sometimes it was forgotten. To avoid miscommunication I developed a quick and easy request slip that I give a stack of to every teacher at the beginning of the year.
These slips are for the teacher to use if they want me to meet with a student about something or they have a concern in general. They can quickly fill it out giving me basic non-confidential information and slip in my mailbox while they are walking down the hall. Enjoy!
