Tuberculin Testing revalidation

What does OCQ(V) - TT (Tuberculin Testing) revalidation involve?

It is now recognised as 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.

Revalidation for the OCQ(V) - TT is required every 4 years. If you do not revalidate, you will not be able to continue TB testing.

The only exceptions to the 4-year revalidation cycle are those who had already studied and been awarded the OCQ(V) - TT before 31st January 2019, whose revalidation will be due 3 years from the date that they passed the online exam and completed the declarations. However, for those who are awarded or revalidate the OCQ(V) - TT after 31st January 2019, your first revalidation will be due 4 years from the date that you passed your online exam and completed your declarations.

Click here for the 2020 OCQ(V) - TT revalidation requirements and information about exemptions.

You may enrol to revalidate and start the process at any time. There will be a 6-month window before the expiry date of your OCQ(V) - TT in which you can complete the revalidation (by signing the declarations) without changing your future revalidation date. We recommend that you don’t leave it until the last minute. You will need to ensure you have enough time to complete ALL the requirements before your expiry date.

If you do not complete revalidation within the permitted timeframe 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 your status has been expired, you will either have to contact APHA in order for your status to be changed to 'suspended' and enable you to complete the revalidation course within 6 months of the missed deadline, or complete the full OCQ(V) course before your OV status can be reinstated. If you wish to appeal the revocation of your status you should contact APHA, as the final decision rests with them. If you are aware of any exceptional or mitigating circumstances it is worth contacting APHA as soon as possible to avoid the necessity to retrain. Please see the APHA Briefing Note 15/19 for more information on the options available to you if you have missed a revalidation deadline. You can view a flowchart illustrating these by clicking here.

Improve International will send email reminders to OVs prior to the expiry date of the OCQ(V) - TT.

Online training and exam

Revalidation is undertaken by accessing the online training platform.

Everyone studies at their own pace, but the revalidation course will equate to 3 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. Candidates completing the online exam are required to do so in the presence of an MRCVS (this can be a DVM for overseas students), an RVN, a doctor or a lawyer. Both the candidate and invigilator will be required to sign the disclaimer and give their professional membership number before the online exam takes place. Any false certification, including the impersonation of another MRCVS or violation of any of the "ISVPS Rules for Examination Candidates", may be reported to the RCVS (or corresponding authority for overseas students) for investigation as potential professional misconduct, and may result in disciplinary action being taken against the candidate by ISVPS, or the revocation of the relevant status with APHA or RCVS.

Once you have passed, you will be able to download a certificate of achievement.

If you fail the exam you have two opportunities to resit. A week is allowed for further study and you do not have access to resit the exam until after this week. If you fail for a third time your status will be revoked and you will have to take and pass the full OCQ(V) - TT course to regain your OV status

Scenario exercises

You will be required to complete 3 scenario exercises, which should be uploaded to the case log section of your OCQ(V) - TT Personal 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 Personal Training Dashboard and from within the OCQ(V) - 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 30 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.

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 to provide evidence of relevant CPD that you have undertaken to support this field of work. You will be expected to have completed at least 10 hours of relevant CPD within the revalidation cycle, which can include the 3 hours spent on the revalidation course and any additional time spent completing case logs and certification exercises for the revalidation course (no more than 1 hour per exercise).

CPD should be recorded on your Personal Training Dashboard and you may want to start updating it now and do this as you go along, rather than waiting for revalidation to begin. Whilst the CPD should be relevant to this OCQ(V) - TT, it is possible to use the same CPD for other OCQ(V)s. Please highlight which of your OCQ(V)s each CPD activity applies to.

The type of activities that would count as relevant CPD for the OCQ(V) - TT 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 colleague's TB testing
  • Reading the TB OV Instructions and APHA policy updates
  • Discussing your TB audit or peer review with your auditor or colleague

Testing audit

You must have also passed an audit of your TB testing within the revalidation cycle. 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 OCQ(V) - TT Personal 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. After the TB test has been conducted in the presence of your Peer Reviewer, you must upload the report with your scenarios/case logs. 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, ISVPS. ISVPS will sample 10% of records within 1 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 ISVPS and offered an opportunity to update it to a satisfactory condition. If it is updated satisfactorily within 1 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 passed the online examination you will be asked to confirm the declarations below:

I confirm that:

  1. In this revalidation cycle, I have undertaken at least 10 hours of CPD that is relevant to the OCQ(V) - TT and have completed my CPD log on my Personal Training Dashboard to evidence this.
  2. I have uploaded 3 scenarios or case logs.
  3. I have tested 30 cattle in the current revalidation cycle OR I have been granted an exception to these requirements by APHA and have uploaded evidence as agreed with APHA.
  4. I have self-reflected on any feedback I have received from colleagues, clients and APHA.
  5. I have successfully passed a TB testing audit in this revalidation cycle or have received a positive peer review. (Please specify in the box.)
  6. I consider that my knowledge of my legal and professional responsibilities is current.
  7. I have accessed the latest version of the RCVS Code of Professional Conduct and refreshed my knowledge of the following sections: Clinical Governance and Certification.
  8. I have accessed the OV Instructions within the last year.
  9. I have checked that my personal contact details, including my unique email address, are up to date and that I have been receiving OV communications.
  10. My signature is uploaded and is both clear and correct. (You can check your signature by downloading a certificate of authorisation. If you need to update your signature you can replace the one you originally uploaded by going to the 'Update details' section.) 

Please note: If you cannot tick one or more of the above declarations but do wish to revalidate you can appeal to APHA as an exception. If you are granted an exception there will be a box for you to tick.
