As an admin, you are able to set advanced options for students, that will enable them to self schedule, or to send a school-wide password to all students.
Logged in as an admin, click 'Settings' in the navigation. From here, select the button that says 'Advanced' at the top right of the page.
One box you will see is the 'Manage Student Self Schedule' box. By checking the 'Can Self Schedule' check box, you will enable students to self schedule. In the drop-down, you can choose whether this will be all students, or students in a specific graduation year.
If you select 'By graduation year', you can then select which graduation year to set that students may self schedule. Click 'Save', and these changes will be made.
The 'Set Passwords for All Students' box, allows you to set one password for all students school-wide. This is helpful for the beginning of the year, to make it easy for all students to login with one password. However, for security reasons it is strongly recommended that you encourage students to create their own password once they are able to login. Click 'Save' to make these changes.
