Always address instructors and staff members with respect by answering Yes (Sir/Ma’am), No (Sir/Ma’am), Excuse me (Sir/Ma’am). When greeting them in the school, it is always Mr./Ms. and the instructor’s last name, with the exception of our Master Instructors and then the Greeting should be Master and the master’s last name. When in class, it is critical for students to show courtesy and respect for instructors and fellow students.
