If you've ever tried to contact a parent by phone regarding student behavior in the classroom, you know that, more often than not, the phone numbers listed in the computer are out of date and no good. I've found that sending a letter home is the fastest way to communicate with a parent about a child's behavior.
This document contains two letters: the first is a letter addressing poor behavior and includes a list of the 21 most common behavior issues, including excessive talking, lack of effort, disturbs others, inattentive, missing assignments, grade of "F" at this time, and more. Simply check the issue(s) that you're encountering with the student, provide a brief explanation, and the ball is in the parent's court.
The second letter is to praise or compliment a student. The squeaky wheel gets the grease, as they say, and in the classroom the "bad" students get the attention. This praise letter is a quick and easy way to let a parent know that his or her child is a pleasure to have in class.
Since it's a Word document, the letter can be customized with issues specific to your school or classroom, as well as your own phone number and email address.
