Class signings refer to a special event where students gather together to sign their yearbook. This is usually done during their last few weeks or days of school before graduation, and it's an opportunity for them to leave messages, well-wishes, and memories for each other in the pages of the yearbook. It can also be a time for teachers and staff members to sign as well, showing their support and appreciation for the students. Overall, class signings are a fun tradition that helps to create lasting memories and bonds among students and faculty.
