Welcome! If you are a Google Apps school, your Google Calendar allows you to set up appointment blocks on your calendar that people can reserve. For instance, parents can sign up for pre-selected times to meet with you. Or parent teacher conference slots can be booked in a snap. Office hours, no problem, students can sign up for those, too.
This tutorial video will illustrate the process for setting up google appointment slots. This feature is only available through your Google Apps, or School Gmail, Calendar account. Personal Gmail’s do not have this feature enabled.
