For the Billing Category, which option do I choose?

The available billing categories are available as follows:

• Endorsement – Student wishes to add an endorsement to an existing CSE certification
• Initial Certification – Student is beginning a new certification
• Initial Certification (optional only) – Student completed mandatory exams and wishes to add optional modules with a new instructor
• Recertification – Students have previously completed IPC Certification and wish to renew that certification
        (Note: This category currently only provides a discount for the CSE program. CIS and CIT programs are priced the same in this category and the Initial Certification category.)
• Retake – Student failed exam twice and requires additional attempts
• Retake Endorsement – CSE student has failed an endorsement exam twice and requires additional attempts
