Under the Student/Parent/Guardian/Personnel Keywords group, there are 11 User KW fields that you can customize. These can be anything you want to track that isn't already covered by a keyword or field.
Assign the name of the keyword, such as "Occupation", and set up the options you want in the keyword list. For example, under Occupation, you can enter "Accountant", "Secretary", "Doctor", and so on. By default, the first three User Keyword names are set up. You can change these even if you transferred data from an earlier version of PDS.
