Tuberculin Testing revalidation

What does OCQ(V) - TT Revalidation involve?

It is now recognised good practice to ensure that we all remain up to date with the latest policies, advice and techniques for the work that we do. Revalidation is your opportunity to do this and it is certifiable CPD.

From now on revalidation for the OCQ(V) -TT will be required every two years. Without completing this you will not be able to continue TB testing.  If you have studied and been awarded the OCQ(V) - TT your first revalidation will be due two years from the date that you passed your theory exam. From then on it will be due two years from completion of your revalidation.

You may apply to revalidate at any time, we suggest that you don’t leave it until the last minute. and you may apply to take the revalidation OCQ(V) - TT module up to two months before your expiry date without changing your revalidation date in the future. You will need to ensure you have enough time to complete ALL the requirements before your expiry date.

If you do not attempt to complete revalidation within the permitted time frame your status will be expired by APHA. If this happens you will be informed by email from APHA and you will not be allowed to use the OCQ(V) - TT. Once expired you will have to enrol and successfully complete the full OCQ(V) to regain your status. If you wish to appeal against your status being expired you should contact APHA as soon as possible, as the final decision rests with them. If you are aware of any exceptional or mitigating circumstances it is worth contacting both Improve International and APHA as soon as possible to avoid the necessity to retrain.

If you are in the process of revalidating but have not successfully completed it before the deadline perhaps because you are waiting to retake your exam, you will have one month from the revalidation date to complete the process. During this time your status will be suspended and you will be unable to use your OCQ(V) - TT. If you revalidate successfully within this month, your status will go back to normal and will not be revoked or expired.

Improve International will send email reminders to OVs prior to the expiry date of the OCQ(V) - TT. If you do not intend to revalidate the qualification please log in and tick the 'I do not intend to revalidate this qualification' box. This will stop the reminder emails.

Online Training and Exam

Revalidation is undertaken by accessing the online training module.

Everyone studies at their own pace but the revalidation course will equate to three hours of CPD. You may access the training in your own time and it does not have to be completed in one go. Once you are ready you may then proceed, via your personal training dashboard, to the online exam. You are allowed 30 minutes for this online exam which involves answering 10 multiple choice questions.  You will be required to nominate an invigilator for this exam. Candidates completing the online assessment are required to do so in the presence of a MRCVS (or a DVM for overseas students). If you live in a remote area and have no veterinary colleagues you may complete the exam in the presence of another professional colleague such as a doctor or lawyer.  Both the candidate and invigilator will be required to sign the disclaimer and give their professional membership number before taking the online assessment. Any false certification, including the impersonation of another MRCVS, may be reported to the RCVS for investigation as potential professional misconduct.

Once you are successful you will be able to download a certificate.

If you are are unsuccessful with your online assessment, you will have an opportunity for two retakes. There is a one week study period before a resit and the exam can’t be accessed in this time. If you are still unsuccessful you will have to take the full OCQ(V) and your status will be revoked by APHA in the interim.

Scenario Exercises

You will be required to complete three scenario exercises which should be uploaded to the case log section of your TT training dashboard. These are intended to replace the requirement for case logs but if you have already written case logs you may still upload these, as before. You can download the scenario exercises from your OCQ(V) TT training dashboard and from within the TT revalidation course. The scenarios each describe a situation that you might encounter at a TB test and ask you to describe the actions you would take and/or the advice you would give the farmer.

The scenarios do not require you to provide evidence that you have tested at least 250 cattle. You will be asked to confirm this when you sign the declarations. You must apply to APHA under the exception/exemption rule if you are not able to sign this declaration. (See the details in the case log section below)

Case Logs

This requirement has now been replaced by the scenario exercises but case logs will still be accepted if you already have these prepared.

You will be asked for case logs to provide evidence that you are fulfilling the minimum testing requirements of the OCQ(V) - TT to maintain your skills. Case logs must be from at least three different farms and evidence that you have tested at least 250 animals within the two year revalidation period. There will be an exception to this minimum number for specialist vets who test a variety of species other than cattle or cattle vets who work in remote locations or very low TB testing areas where they will still be required to maintain their ability to TB test. The policy for this can be found here. If you think this applies to you please contact the  APHA OV Team providing evidence as to why APHA could consider your situation to be exceptional (CSC One Health OV Team (APHA). There are guidance notes on submitting case logs on your TT training dashboard and you can upload your case logs to your dashboard at any time. This is also an opportunity to review cases with colleagues and receive feedback on your work.


You must provide evidence of at least ten hours CPD relevant to the OCQ(V) - TT over the two year revalidation cycle. This can be uploaded to your personal training dashboard at any time.  Examples of relevant CPD are:

  • Supervising a Conditional TT OV and completing the Supervisor training course
  • Completing the OCQ(V) - Cymorth TB
  • Attending a TB Farm Advice Workshop
  • Completing the TB Farm Advice course
  • Reading relevant  articles in the Vet Record, OV Magazine and other Veterinary publications
  • Webinars on TB and TB Biosecurity
  • Attending the OV Conference and other relevant Conferences.
  • Peer Reviewing a colleagues TB testing
  • Reading the TB OV instructions and APHA policy updates
  • Discussing your TB audit or Peer Review with your Auditor or Colleague
  • Completing the Revalidation course

Testing Audit

You must have also passed an audit of your TB testing within the two year revalidation period. The audit can be from your Veterinary Delivery Partnership (VDP) or from The Animal and Plant Health Agency (APHA). If you have not had an audit then you have the option to arrange for a colleague to undertake a ‘Peer Review’ of your testing. You may also be asked to review a colleague. You must nominate your colleague from your TT training dashboard. They will then receive a short online course from Improve International explaining the review process. We advise that if you take this option, you make arrangements with your colleague in good time; they need time to study the short online course and arrange to join you at a suitable test. If you are unable to arrange a peer review then please contact the Improve International office. We may be able to arrange the review for you, however there will be a charge for this, which will vary depending on your individual circumstances, including location.

Internal Verification (IV)

Once you have passed the online exam and ticked all the declaration boxes to confirm compliance and completion of your CPD record, case logs and audit, your revalidation will proceed automatically and you will be able to download a new certificate of authorisation.  However, there will be a process of internal verification of the CPD and case logs by the awarding body, ESVPS. ESVPS will sample 10% of records within one month of completion of all revalidation requirements. If your record is in the sample chosen, and is not up to the required standard, you will be contacted by ESVPS and offered an opportunity to update it to a satisfactory condition. If it is updated satisfactorily within one month, then no further action is required. However, if it is not updated satisfactorily within the required time this will be reported to APHA who will then review your case and may suspend or revoke your OV status. Please note the ultimate jurisdiction is with APHA.

Final Declarations

Once you have successfully passed the online examination you will asked to confirm the declarations below;

I confirm that-

  1. I have undertaken at least 10 hours CPD  relevant to my OCQ(V) - TT OV responsibilities, in the past two years, and have completed my CPD record on my personal training dashboard
