Online applications

Applications that are completed and submitted through our online system(external link) automatically get sent to the BoE Secretariat for processing.

For your application to be considered complete, you must provide all required information and supporting documents. If your application is considered incomplete you will be given 10 working days to provide the requested information or documents. If you have not provided this within the 10 working days your application and supporting documents will be returned to you.

You will need to reapply for your CoC when you have the correct documents, ensuring your Ministry of Justice criminal record check is still dated within three months and first aid certificate is still current.

For more information, see our Incomplete applications policy [PDF, 47 KB].

Once your completed application has been reviewed, logbook approved and a date has been set for your oral exam you will receive a letter outlining the date, time and location. Scheduling of oral exams is based on availability of suitable panel members and the number of applicants applying for similar CoCs. Your oral exam could take place up to a few months after the BoE has received your complete application and you should allow approximately one hour for the exam.

An oral examination panel consists of three members who will mostly be senior colleagues from the extractives industry relevant to your CoC. A member of the Board’s Secretariat is also present to ensure the Boards processes and procedures are followed. In some instances, such as moderation, the Board wishes for observers to be present during an oral exam. If this is the case you will be asked for permission prior to your exam.

The panel will assess you against the benchmarks set out in the High Level Oral Exam Framework [PDF, 243 KB]. The panel will use workplace-based scenarios to assess you against these benchmarks. The scenarios may include follow up questions. You will be asked to demonstrate the application of your skills and/or knowledge relevant to the CoC. This means that the panel will expect you to talk about the scenarios you have been presented with, including the actions you would take, putting into practice what you have learnt and explaining why you have taken the action(s).

The scenarios will cover these four competencies:

  1. Operating and Safety Systems
  2. Legislation
  3. Emergency Management
  4. Leadership.

Each competency has a range of topics which can be found in the High Level Oral Exam Framework on page 3.

For more information, see our oral examination policies.

Outcomes after oral examination

It can take up to 2-3 weeks after your oral exam for a response to come back from the BoE on the outcome of your overall application.

If the BoE finds you competent and grants you with your B-grade tunnel manager CoC, a letter will be sent to you along with your certificate and information on CPD requirements.

If the BoE finds you not yet competent and declines your application for your B-grade tunnel manager CoC you will receive a letter including extracts from the report from your oral examination. This will assist you in preparation should you wish to reapply.

You can reapply and re-sit the exam at any time.

As a holder of a CoC you must demonstrate that you have complied with the continuing professional development (CPD) requirements when renewing your CoC.

CPD requirements are prescribed by WorkSafe and the BoE renews all CoCs. 

To find out more, see our information about CPD and your requirements.
