From Teachers Pay Teaches:
"As you begin your teaching career, one of the most important tasks you must complete is the creation of your Teaching Portfolio. This will be your professional folder that well represents what you will be as a classroom teacher. Many universities require this as part of their academic program, yet others do not, leaving many unprepared as they step into their first interviews for those rare teaching positions.
Use this checklist to create an impressive professional Teaching Portfolio that you will be proud to share as you navigate the teaching field."
