The “County Government Reorganization Act of 1988” specifies that all county centralized purchasing officials—purchase clerks, receiving clerks, and inventory control clerks—must be certified in their positions at the beginning of a new term of office or within one year of their appointment. Certification requires attending a certification seminar and successful completion of an examination covering the material taught during the seminar.

All clerks not yet certified in their positions must attend the seminar. Deputy clerks, assistants, and other are welcome to attend, but they will not the certification examination.
