Passing Grade and Certification Maintenance

Successful Candidates for the CZO® Certified Zoning Officer Credential will received a score of 80% or better on the test.

Thereafter, the Certified Zoning Officer must obtain a minimum of 15 CEUs in zoning, code enforcement, or building inspection within every three (3) year period thereafter to maintain the certification. CEUs or additional category certification obtained for other professional certifications, such as for PA UCC certification maintenance, are reciprocal with PAAZO CZO® certification maintenance. PAAZO is an approved PA UCC continuing education provider.
