This idea comes to us from Saint Joseph's. They have an event called Final Fridays, which happens on the last Friday of each month. It's basically a themed party for the students.
Those who do not earn enough LiveSchool points to attend stay back in a study hall with a volunteer teacher. Everyone else gets a chance to play, sing, and hang out with their friends depending on the theme. The school markets these events with posters.
They are so popular that if they forget, students are fast to remind them that they need to plan Final Friday. Clearly, the students of Saint Josephs are invested!
