Credentials From Tom Walters, a teacher at Camel's Hump Middle School and Mount Mansfield Union High School in Jericho, Vermont: "Lawyers do it. Doctors do it. Educators should do it! No, I'm not talking about making a lot of money! I'm talking about prominently displaying educational degrees and professional certificates. Displaying one's credentials will help you appear professional and legitimate. It's very impressive and reinforces to the public the amount of effort it takes to become a teacher and to maintain certification."
