CCO certification is valid for five years. Candidates must complete all of their recertification requirements during the 12 months prior to their certification’s expiration date.

The information below applies only to the CCO Signalperson certification program. This program is unique in that it requires a practical recertification exam, while other CCO programs require a written recertification exam.

Recertification requirements include:

*The Signalperson Recertification Practical Examination is identical to the initial Signalperson Practical Exam, which consists of 20 scenarios with no time limit. Candidates typically complete the exam in approximately 15 minutes.

Recertification candidates are allowed two attempts to pass the Signalperson Recertification Practical Exam before their certification expires. Candidates who are unsuccessful after two attempts must take and pass the initial Signalperson Practical Exam.

There is no grace period after certification has expired. Candidates whose certification has lapsed must take the full Written and Practical Examinations to be certified again.

Certified candidates may take their Recertification Practical Exam up to one year prior to their certification’s expiration date. 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 of the candidate’s initial certification. [Note: Candidates who recertify more than 12 months prior to their certification’s expiration date will have their new certification period begin immediately, not from the end of their current certification period.]
