For the child exit summary report, you will go to the Child tab, and then click on "non-Actives" on the left. Next, click on "Exited Children". You can sort the list by exit date (click the arrows to the right of the exit date column). On the far right side, you can click the check box of the children you want to print the reports for and at the bottom you will see a button that says "Print Checked Exit Reports". This will open the reports in a PDF format that you can review and then print.
To get Guardian exit summary reports, you will go to the Reports tab, and click to run the Service Record report. Change to Guardian report. You can select the guardians you want to run get the reports for.
Hope this helps!
