Professional Santas from all around the world travel to the Charles W. Howard Santa Claus School in Midland, Michigan, to learn about all things Santa Claus before the start of the holiday season. Referred to as the “Harvard of Santa institutions,” it's been in operation since 1937, making it the oldest Santa school in the United States. During the three-day course, Santas learn how to sound like Santa, use American Sign Language to communicate Santa-related phrases, and answer questions from children.
