National Skip Day, also known as International Ditch Day, may refer to the practice of not attending classes the day after the school football team wins a big game, or to the day when seniors collectively skip classes. National Skip Day occurs at both the high school and college level.
There are various traditions in high schools and colleges that encourage groups of students to skip classes or an entire day. Students in the United States and Canada use the day for fun group activities before big events like the school prom or final exams. The origins of National Skip Day are unknown, and schools have stepped up efforts to combat the issue, such as the use of police to search for truants.
