The Custom Reports—Set Portal Options tool manages which custom reports and transcripts are displayed on the portal by school. The Calendar and School are based on the calendar and school the user has rights to and has selected in the action bar.
Select the report to display in the portal for each school, then click Set Portal Status. The Check/Uncheck All option can mark all options en masse. Parents/guardians with students at the selected school can view the custom report for that calendar.
