On the Admin Dashboard click the Scheduling tab and click Schedules. Select the student you wish to schedule and click the box under the date of the start of their schedule.

Once you've clicked the box, you have the option to add a scheduled time for This week only, Add recurring schedule, or Mark absent for the day.

Here, you can select multiple students with the same scheduling for the week.

Additionally, adding a recurring schedule allows you to set a start and end date for the student(s) selected and the days to repeat a schedule.
