Permission slips are used by schools and other organizations as a formal way of obtaining parents' consent to take underage students on trips that require travel. They may also grant the school permission to host activities that do not fall within the usual scope of the organization. Permission slips also often convey details about the event to the parent or guardian so the parent can provide an informed consent.
Permission slips typically specify information about the event including the date and time of the event, the location, any transportation or travel details and the cost of the event. Some permission slips also absolve the school or organization from any liability in the event of accidents or other unforeseen occurrences.
When parents sign permission slips, they typically provide their own contact information as well as contact information for an emergency contact. In some cities and states, permission slips are legally required to allow adults who are not parents or school officials to transport a child.
When children reach the age of majority, they are technically not required to get permission from their parents to participate in school activities. Some schools and other organizations, however, ask these participants to sign their own permission slips so they have the basic emergency information on record.
