Tower Crane Operator Program Outline

CCO certification  is valid for five (5) years.  Candidates must complete all of their recertification requirements during the 12 months prior to their expiration date.  This includes:
  • Passing the Written Recertification Examination
  • Continuing to meet ASME physical requirements
  • Compliance with NCCCO's Substance Abuse Policy
  • Compliance with the Code of Ethics

Candidates who can document at least 1,000 hours crane-related experience during their period of certification, do not need to take the Practical Exam to recertify. Crane related experience is defined as: operating, maintenance, inspection or training. 

However, candidates who do need to take the Practical Exam must do so before their certification expires.  There is no "grace period" after the date of expiration.  Candidates whose certification has lapsed must take the full written and practical examinations over again in order to be recertified.

The Tower Crane Recertification Exam consist of one thirty (30) questions exam.  The candidate has forty-five (45) minutes to complete the exam.

Recertification candidates are allowed two (2) attempts to pass the Tower Crane recertification written exam before their certification expires.  Candidates who are unsuccessful after two (2) attempts must take and pass the regular Tower Crane written exam.

Certified candidates may take their written recertification examination up to one (1) year prior to their date of expiration.  Regardless of the date of the recertification examination within that one year period, the new five-year certification period begins from the date of expiration on the candidate's initial certification.

[Note: Candidates who recertify more than 12 months prior to their expiration date will have their new certification period begin immediately, not from the end of their current certification period.]

Recertification Exams are available at regularly scheduled test administrations.  Candidates wishing to recertify should contact the Test Site Coordinator who set up their initial certification. Candidates whose employment circumstances have changed should ask their new employer to schedule a test administration.
