A visitor log form or sign-in sheet is a document used to keep track of whom is present during a tour, workshop, or other formal gatherings. In a school, a visitor log form is typically kept by a teacher or parent volunteer during a class open house or Parent-Teacher Conference Night. In a business, a visitor log form can be used to record employee attendance, customers, or a list of people present at a training session. A visitor log form is a good way to keep track of who is present during a class or event, while also making sure no one was accidentally left out. A visitor log form can also serve as a record of who was present for an event, unlike a guest list, which is a record of who has been invited.
