Student, Teacher, and Enrollment data can deleted very easily, but only if the data was just imported and not used.
Open the data file that you imported in Microsoft's Excel or another spreadsheet program.
Add a column to the data and fill it with the word "delete".
Put the word "Action" in the first row of that column.
Save the file as tab delimited text file, and re-import it.
IMPORTANT NOTE: Once the class data has been imported teachers become resources in the system and their information in the Contact section of the site can not be changed. See Teachers and Resources for additional details.
To remove all contacts (parents, teachers, and students) from your account go into the Global Setup / Contacts Setup tab. At the bottom of the page you will see a button "Remove all customers." This will remove all contacts from the database. Selecting this button will bring up a pull-down where you will have the option of deleting your contacts by administrative access level. You would use this button if you would like to remove all previous log in information from your parents. You would also use this if you would like to remove all student and teacher data that you have imported and start with a new import. Note, that this will not remove any contact that has full powered Administrative access. Also, it will not remove any parent who has logged in during the previous month.
You should not delete the students or teachers after the system has been used. If any parents have made appointments for the students that will be deleted, then the student information for those appointments will be lost. The appointment will remain, but the system will no longer be able to prevent the parent from booking more than the allowed number of appointments.
