How can I export a list of all of the students that don't have parent information?

To get the list of students, go to Admin/Export page and click on the “Export students in the student parent import format (Tab Delimited)” link.

This will produce a tab delimited file that you can open in Excel (or another spreadsheet application). All of the students will be listed in the file alphabetically.

If a student has no parents, then the columns for Parent1 will be blank. You can sort on parent1_last_name to move all of the students without parents to the top of the sheet. Remember to highlight all of the columns of the spreadsheet before sorting.

You need admin rights to perform the export.
