I usually have a red flag when a student fails to show for the first class. It seems many students see this day as a waste of time because so much can focus on the mechanics of the class, syllabus and expectations. While this is partially true, a savvy teacher keeps the first day interesting and “hooks” the students. When you get the “no-show” they miss that important interaction. A follow-up and connection to the new studding will be needed to ensure they integrate into the program and this also lets the student know you are watching and actually care about their participation.
