I made these hall passes at the beginning of the 2012-2013 school year. They have been amazing and have lasted all year! I printed them on card stock and slipped them inside ID badge covers that clip-on clothing. The best part is that you don't have to worry about them getting wet with unidentifiable liquids when students go to the restroom! Add your name to allow school staff to know where your students are coming from. There are also 4 blank passes to personalize.
UPDATE: I have included both the PDF and an additional editable Word Doc.
