Mobile Crane Operator

How Do I Test? Practical Exam



The CCO practical examinations are available on three crane types:

  • Lattice Boom Crane (LBC and LBT): includes lattice boom crawler cranes and lattice boom truck cranes
  • Telescopic Boom Crane—Swing Cab (TLL): cranes having an operator's station that rotates with the crane's upperworks
  • Telescopic Boom Cranes—Fixed Cab (TSS): cranes having a fixed (non-rotating) operator's station

NOTE: Candidates seeking the Boom Truck—Fixed Cab (BTF) certification are required to take the exam on a boom truck. All testing parameters (e.g., time limits) follow those for the TSS practical exams.

Candidates may take the practical examination on one, two, or all three of the crane types provided they have already passed/will pass the written examination in the corresponding designation within the 12-month time frame.

The practical examination is comprised of six main tasks that increase progressively in the skill level tested. Skills tested are: inspecting the equipment, hoisting, booming, swinging, following hand signals, and combination (multifunction) operations. Crane operation with load and without load is required.

NCCCO adapts the Test Site Layout (CAD) for each model of crane used for the Practical Examination to ensure the examination remains standardized for all candidates, wherever and whenever they may test.


Candidates for the Practical Examination should contact their Test Site Coordinator to determine the date of the next scheduled Practical Exam. Candidates may also view a list of Permanent Practical Exam Sites to find a location.


Candidates must report to the Test Site at the scheduled time. All candidates shall comply with Test Site requirements concerning personal protective equipment (PPE), which at a minimum shall meet OSHA requirements.


Candidate performance on the Practical Examinations is recorded by Practical Examiners accredited by NCCCO. Examiner requirements include meeting NCCCO requirements for certification, passing the Written and Practical Exams, and successfully completing an accreditation workshop.

The testing procedure has been developed to provide the highest degree of standardization and reliability. The Examiner’s task is primarily to record the performance of the candidate.

A candidate may lose points either through operational errors or exceeding established optimum time limits. Candidates’ performances are scored off site at the facilities of International Assessment Institute.


All candidates receive score reports of their performance. Examination results are mailed to candidates approximately 12 business days after the receipt of Practical Examination score sheets by International Assessment Institute.

Please note that while Practical Examiners are encouraged to expedite score sheets after each test administration, they may batch score sheets from several test administrations over a number of days. This means that candidates may receive their score reports from IAI more than three weeks after their test administration.

Both the Practical Examination and the scoring system have been validated by NCCCO’s pilot testing program and verified by International Assessment Institute. A score of 75 represents the minimum passing score for Mobile Crane Practical Examinations.


The examination fee for testing on one crane type is $60. For each additional crane type applied for and taken at the same time, the fee is $10. The appropriate fees must be submitted with the practical exam application through the Test Site Coordinator. The same fees apply for retest exams.

Practical Candidate Fees:

  • 1 Crane Type: $60
  • 2 Crane Types: $70
  • 3 Crane Types: $80


Candidates not passing the examination(s) may request from International Assessment Institute hand scoring of their answer sheets, provided the request is made in writing within three months of the test date. Requests must be accompanied by a processing fee of $25 for each test requested. Request(s) should be mailed to:
