I try to register for a course and the system keeps telling me that I need to enter more personal information.

You need to complete all of the information in your personal record, such as

Social Security Number

Work Phone

Home Phone

Home address

District

School

Position

Subposition
If you have not entered this information, you will not be permitted to register. You only need to do this once a year. On August 1 of each year you will be required to reenter all of this information. This is to insure that your record is current and correct.
