NCCCO-accredited Practical Examiners are CCO-certified personnel who have been trained and authorized by NCCCO to administer the practical examinations for CCO certification programs. NCCCO Practical Examiners are recognized as professionals in their field and may offer their services for hire. Employers with NCCCO-accredited Practical Examiners on staff appreciate the convenience of being able to schedule in-house tests to accommodate changing schedules caused by weather, workloads, and other factors.

NOTE: NCCCO maintains an online directory of accredited Practical Examiners available for hire to assist employers seeking Practical Examiners to administer CCO Practical Examinations. Practical Examiners’ current accreditations are tracked in the Verify CCO Online (VCO) system.

Accreditation Requirements

Accredited Practical Examiners are authorized to offer the CCO Practical Exam at approved NCCCO Practical Test Sites. Scheduling of such tests is done through the Test Site Coordinator responsible for each site.

Practical Examiner accreditation is good for five years. Once accredited, you will receive a Practical Examiner packet with the documentation necessary to conduct CCO Practical Exams. After the completion of a clean audit, you will also receive an official NCCCO accreditation card listing the programs for which you are accredited.

To be an NCCCO-accredited Practical Examiner, you must:

  • Be able to document some crane operating experience
  • Be certified by NCCCO in the program you are seeking accreditation for prior to attending a Practical Examiner Accreditation Workshop
  • Attend an NCCCO Practical Examiner Accreditation Workshop, during which your performance as an Examiner will be observed and evaluated
  • Pass the Practical Exam(s) in the presence of an NCCCO Auditor for the crane type(s) you are seeking accreditation (even if currently certified)
  • Pass a Practical Examiner Accreditation Written Examination
  • Pass a Practical Examination audit
  • Have a direct email address to receive email notifications from NCCCO (this may not be a shared address)

If you fail the practical test during your audit, within 30 days you must pass a practical test in that category administered by an NCCCO Auditor selected by NCCCO, and the cost of this examination must be borne by you. This requirement must be completed, even if you wish to no longer pursue NCCCO accreditation.

Practical Examiners receive regular updates on the NCCCO Practical Examination Program via emailed Information Bulletins. These updates are also posted in a password-protected area on NCCCO’s website for Practical Examiners only.

Accredited NCCCO Practical Examiners are not permitted to participate as Practical Examiners in any non-CCO crane-related personnel certification programs.

Practical Examiners who have been assigned a username and password for the login section of the NCCCO website can recover their password via a link on the login screen. If the email address entered to retrieve the password is not the same as the one in the database the password recovery link will not work. Those who have not yet been assigned a password or provide the incorrect email should email Erin Jones (ejones@nccco.org) to receive or recover their password.

If, at any time, you have questions about any aspect of the NCCCO Practical Examination Program, contact the NCCCO Western Regional Office at 801-363-2693 or via email at ejones@nccco.org.


At the completion of the Practical Examiner Accreditation Workshop, you will receive a Certificate of Attendance. This verifies that you have attended and participated in an official NCCCO Practical Examiner Accreditation Program Workshop. Within three weeks you will receive a notification letter from NCCCO informing you of your provisional Examiner accreditation status.

After completing and receiving the results of the PEAP workshop, provisional Examiners must request and complete a clean audit, where they will demonstrate the ability to set up and administer a practical exam with a mock candidate.

Practical Examiner applicants who do not pass the PEAP written and/or Practical Exam(s) during their audit must be subsequently retested by an NCCCO Auditor. They will receive full accreditation only in the categories for which they hold certification and have successfully passed the PEAP written exam and Practical Exam(s) with an NCCCO Auditor present.


A probationary Examiner is defined as:

  • An individual who does not hold accreditation in any other CCO program
  • An individual who has allowed his/her accreditation to expire
  • A Practical Examiner who has not administered an exam within a 24-month period
  • A Practical Examiner who has been required to re-attend a full workshop

The purpose of this probation is to monitor examiners and ensure that they are following NCCCO’s policies and procedures. These procedures include proper notification of testing, proper cancellation notice, and cooperation in the audit process.

Probationary Examiners begin a 12-month probationary period after the completion of a clean audit. If a clean audit is not obtained, a second audit is required and a fee of $1,000 charged.

After a 12-month time frame, a probationary Examiner’s history is reviewed to ensure that he or she has followed NCCCO’s policies and procedures, including the notification procedures. If an Examiner has not been providing proper notification, the probationary period will be extended at six-month intervals until such time that the policies and procedures have been properly followed.


Probationary Examiners are required to notify the NCCCO Western Regional Office of their intention to test. This notification must be sent via the NCCCO website (www.nccco.org/login) not less two business days (not including weekends or holidays) prior to testing. Once a site has provided test notification to NCCCO, this will be considered intent to test and the site may be audited even if no testing occurs. They must also notify NCCCO if testing plans change.

Other criteria for determining which Examiners must use the online notification system include:

  • Practical Examiners at new Practical Exam sites
  • Exceptionally high or low pass rates
  • Practical Examiners chosen via a revolving random selection
  • Practical Examiners who NCCCO has reason to believe have intentionally sought to avoid a Practical Exam Audit

For the final three criteria listed, NCCCO will indicate that you meet one or more of the specified criteria and when you will be required to begin using the online notification system.


Examiners holding Operator program accreditations (Mobile, Tower, Overhead, Articulating, Service Truck, Dedicated Pile Driver, and Digger Derrick) may attend any operator refresher workshop, which are held the day before full Operator Accreditation workshops. They are designed to cover all operator programs, not just the program addressed by the full Workshop that is usually scheduled for the following day.

Prior to the end of your five-year accreditation period you will be notified of your need to re-accredit. To re-accredit, you must meet the requirements for a CCO-certified crane operator and:

  • Attend a one-day Practical Examiner Accreditation Refresher—Operator Programs Workshop (if you have more than one operator accreditation, you may attend just one refresher to cover all operator accreditations)
  • Attend a full operator workshop to earn accreditation in an area you are not yet accredited

NOTE: Rigger or Signalperson Practical Examiner Accreditation Workshops do not meet the above requirements for operator Practical Examiner Accreditation Refresher Workshops, and vice versa. Signalperson refresher workshops are held in conjunction with full Signalperson workshops. Rigger Refresher workshops are held at the beginning of each regularly scheduled Rigger Practical Examiner Accreditation Workshop.

Practical Examiners accredited in more than one operator program have only one accreditation period. Practical Examiners adding an operator accreditation prior to 12 months before their expiration date will have that workshop count as a refresher for all previously held operator accreditations and will reset their five-year operator accreditation period for all operator accreditations. Practical Examiners adding a new operator accreditation within the last 12 months of their expiration date, however, will have that workshop count as their refresher for all previously held operator accreditations, and their five-year cycle will remain the same.

For example, mobile crane operator Practical Examiners who subsequently add the tower crane operator accreditation will have their accreditation period reset and will start a new five-year accreditation cycle. If they add the new accreditation during the 12 months prior to the end of their mobile crane operator accreditation period, however, they will have that workshop count as a refresher for their initial accreditation(s), and this will extend their five-year operator accreditation period for all operator accreditations.

Practical Examiners whose accreditation has expired must return all confidential exam materials in their possession to NCCCO’s Western Regional Office.


Accredited Practical Examiners must administer at least one Practical Exam in every 12-month period to maintain accreditation. Practical Examiners accredited in mobile, tower, overhead, or articulating cranes and/or digger derricks may administer a mobile, tower, overhead, or articulating crane or digger derrick operator Practical Exam to meet this requirement.

For example, if you last gave an exam March 2012, you are required to test again by March 2013. If, in April 2013, you have not yet given a test, to avoid attending a Refresher Workshop you must schedule and administer an exam no later than June 2013.

If you are unable to conduct an exam within a 12-month period, an extension of up to 90 days may be granted, provided that you have an exam scheduled within that 90-day time period. To request an extension, please contact Erin Jones at ejones@nccco.org with the scheduled test date and location. You will be notified via email of the status of your request. If you are unable to schedule an exam within the extension period, you must attend a Refresher Workshop to maintain your accreditation.

If you do not administer at least one Practical Examination in a 24-month period, you must attend a full Practical Examiner Accreditation Workshop. Examiners who must attend a full workshop will be considered probationary and are subject to the requirements of probationary Examiners.

NCCCO periodically emails Information Bulletins to all accredited Practical Examiners containing clarifications and updated policies. To remain in good standing, Practical Examiners are required to confirm via a link at the bottom of the bulletins that they have received, read, and agree to abide by the information contained therein.


Practical Examiners may hold accreditation in several CCO programs. Accredited Practical Examiners may add a category by passing the Practical Exam for that crane type at an NCCCO Test Site with an NCCCO Auditor present. To arrange for an NCCCO Auditor, please contact Erin Jones at ejones@nccco.org.

Given their similarities and differences in exam administration, accreditation programs are broken into three areas:

  • Operator (including Mobile Crane, Tower Crane, Overhead Crane, Articulating Crane, Digger Derrick, and Dedicated Pile Driver)
  • Rigger (including Level I and Level II)
  • Signalperson

Each area has its own accreditation period (i.e., issue and expiration date). Within each area, adding an accreditation extends all accreditations within that area a full five years. Take, for example, a current Practical Examiner who holds Mobile, Tower, and Signalperson accreditations. If the Practical Examiner earned Mobile accreditation in January 2008 and added Tower accreditation in March 2010, both Mobile and Tower accreditations would expire in March 2015. If the Practical Examiner added Signalperson in June 2012, his/her Mobile and Tower accreditation expiration date would remain March 2015, and his/her new Signalperson expiration date would be June 2017. In summary, adding any accreditation within a specific area acts as a refresher for all existing accreditations within that area.

Similarly, each area has its own requirement regarding giving at least one exam every 12 months. For example, take a Practical Examiner who holds Mobile, Tower, and Signalperson accreditations. Giving one Mobile exam in a 12-month period would allow the Practical Examiner to maintain accreditations in Mobile and Tower, but not in Signalperson. 

To help Practical Examiners track all accreditation expiration dates, all accreditations are maintained on a single Practical Examiner card, and different expiration dates are noted for each area. Every time a new accreditation is added, the Practical Examiner receives an updated card.

Practical Examiners under current suspension or investigation are not eligible to add another accreditation. Practical Examiners who have been suspended in one program will have their accreditation(s) suspended in all programs for which they are accredited.


For your accreditation as an NCCCO Practical Examiner to remain in good standing, you must also continue to meet all the requirements of a CCO–certified crane operator, including medical requirements. Therefore, in addition to the Practical Examination, you must maintain a passing status on the Written Examinations relating to the crane types in which you are accredited as a Practical Examiner.

If your CCO crane operator certification expires before your accreditation period as a Practical Examiner does, you must certify again as an operator for your Practical Examiner accreditation to remain valid. If you fail your recertification exams and/or your certified-operator status lapses for any other reason, your Practical Examiner accreditation status will be automatically suspended in those categories and you will not be allowed to administer any Practical Examinations in the respective category(s) until your certification has been reinstated.


NCCCO maintains an online directory of accredited Practical Examiners to assist employers seeking Practical Examiners to administer CCO Practical Examinations.

All fully accredited Practical Examiners are eligible for inclusion in this directory at no charge. Please note, however, that your listing is not automatic. You need to confirm that you wish to be included and that the contact information on file for you is current.

If you wish to be included in the Directory, please provide the information requested on the appropriate form in your Practical Examiner Handbook and submit it to NCCCO.


NCCCO conducts audits of Practical Test Sites and Practical Examiners in accordance with the accreditation requirements of the American National Standards Institute (ANSI).

Practical Test Sites and Practical Examiners are selected for audits on the basis of a variety of criteria, including random selection, in response to issues reported by candidates, unusually high or low pass rates, new Test Sites, or probationary Examiners.

Once a site has been selected for audit, the Test Site Coordinator or company representative from the site may be notified by letter from NCCCO prior to the scheduled audit day. In addition, the Auditor will contact the Test Site Coordinator or company representative to verify the testing date and the site address. Unannounced audits may also be conducted.

It is a condition of Practical Examiner accreditation and Test Site status that all test site personnel, including the Test Site Coordinator, Practical Examiner, and Proctor(s), cooperate fully with the NCCCO Auditor during the audit process.

Practical Examiners who have been audited and have been notified that an additional audit is required will be responsible for the expenses incurred by NCCCO for the additional audit. Any Practical Exams conducted by the Examiner will not be scored until NCCCO has been reimbursed for the incurred expenses.


Practical Examiners are responsible for ensuring proper test administration policies have been met, including but not limited to NCCCO policies on unsafe acts, score sheet completion, professional conduct, and site report and/or crane report completion. Practical Examiners are also responsible for ensuring the timely dispatch of properly completed score sheets and other required test administration paperwork to NCCCO.

Examiners are subject to being sanctioned (i.e., having their accreditation(s) suspended and/or revoked) if they commit three Major Infractions within a five-year period. For purposes of this rule, a Major Infraction is defined as follows:

  • Failure to record any scoring aspect on a score sheet
  • Administering a practical examination at an unregistered or suspended test site
  • Submitting a candidate score sheet 30 days or more after a test administration
  • One or more unsafe act submissions that do not qualify as unsafe acts
  • Incorrectly recording a circumvention if it changes a candidate’s pass/fail
  • Any three minor infractions during any one-year period will be deemed to be a Major Infraction. For purposes of this rule, a Minor Infraction is defined as follows:
    • Incorrect or non-submittal of test notifications
    • Not signing a score sheet either by Examiner or Candidate or Proctor
    • Practical Exam scoresheet(s) submitted more than ten calendar days after the Practical Exam (up to 29 days)
    • Incomplete, missing, or incorrect Site Report and/or Crane Report submissions
    • Testing at a registered but inactive site (e.g., annual site fee not paid)

In the event that an Examiner is sanctioned, he/she will be responsible for any expenses incurred by NCCCO in the retesting of candidates whose scores have been invalidated as a consequence of irregularities or uncertainties caused by the sanctioned Practical Examiner. Sanctioned Practical Examiners must immediately return all confidential exam materials to NCCCO.


If you change your address, you must notify NCCCO as soon as possible. Failure to do so may cause you to miss important updates that could affect your accreditation.

Changes of address or other contact information should be made directly to your Profile in the Practical Examiner area of the NCCCO website. To update your Profile, log in to nccco.org/login and then click on “Profile” in the upper right corner to view and edit your information.


Inter-rater reliability exams are used for statistical reporting purposes and are used to measure the reliability between examiners. Where two examiners are available, the second examiner can serve as proctor. Inter-rater reliability exams conducted by the second Practical Examiner will count toward the one exam administration per year accreditation requirement. The second exam (IRR exam) will not be considered for scoring unless informa-tion is missing on the primary score sheet. Additional information (e.g., candidate applications, photos, and fees) should not be submitted for the second score sheet. To request an IRR score sheet, please contact Erin Jones at ejones@nccco.org.
