Participate in art wars
Art Wars is an in-the-moment competition where student artists, from multiple schools, compete against each other to make the best artwork possible in their category. There are multiple categories that include drawing, painting, digital photography, and clay. Students register for a category and are placed in a room with 10-15 other students in that same category. They are given a time period in which to complete a prompt based work of art, all the while being critiqued by the judge in the room.
Want to promote your institution? Why waste your professor's time and money by sending them to high schools to sit in a cafeteria hoping for students to walk by? Instead, bring students to your school. Give them more than a tour, give them an experience with Art Wars.
