Candidate Eligibility

For most CCO certifications, candidates must pass a written exam and a practical exam in the category they wish to be certified in. Candidates have 12 months after the pass the first exam (written or practical) in which to take and pass the corresponding written or practical exam in the same category. Candidates may take their written and practical exams in any order. For example, a candidate passing the written exams (Core + Specialty) in the Telescopic Boom Cranes-Swing Cab (TLL) category in January 2023 has until the end of January 2024 to pass the Telescopic Boom Cranes-Swing Cab (TLL) Practical Exam.

Any tests passed within a 12-month period count towards certification. For example, a candidate who passes the Written Core Exam in January 2023 and the Practical Exam in June 2023 but does not pass the corresponding Written Specialty Exam until February 2024 will then be required to retake (and pass) the Written Core Exam. The Practical Exam would count toward certification until the end of June 2024.

Candidates who have passed the written exam must provide the Test Site Coordinator with a copy of a score report or certification card.

Note that no Practical Exam is required for either the Crane Inspector or the Lift Director CCO certifications; instead, practical scenarios are included in the written exams.
