  7. How to complete and process official TB paperwork and certification for cattle in compliance with both legal and APHA requirements

The qualification requires each candidate to complete the following phases:

  • Nominate an Approved Veterinary Supervisor (AVS)
  • Pass the online exam at the end of the course
  • Complete and return the Sam declaration form
  • Receive conditional authorisation from APHA
  • Conduct practical TB testing under the direct and continuous supervision of the AVS until all practical training requirements have been achieved
  • Pass a Practical Assessment with Improve International
  • Receive full authorisation by APHA to TB test under the direction of the AVS

ATTs with full authorisation will be required to:

  • Have random audits from the Veterinary Delivery Partnership and by APHA



To study the ATT course you must first register on the AHP database. When you register you will be asked to nominate your employer, a representative of your employer, or another representative (a veterinary surgeon who is a Member or Fellow of the Royal College of Veterinary Surgeons (MRCVS/FRCVS)) who will confirm your right to work and eligibility for the qualification.

The person you nominate will receive an email asking them to confirm that the checks have been completed and that you fulfil the requirements. You will be notified by email when this confirmation has been made. You will then be able to log in and enrol on the ATT course.

How do I access the training?

Practical requirements for the OCQ(AHP) - ATT course

The OCQ(AHP) - ATT online course is followed by a period of TB testing under the direct and continuous supervision of your AVS. You will be required to nominate your AVS and complete and return the Sam declaration form before being given conditional authorisation by APHA, which then allows you to start your practical training. When you have completed all the practical requirements of the course there is a Practical Assessment with an Improve International Assessor, which you must pass to be awarded your full qualification. The maximum period that you can hold conditional authorisation for is six months, but it is expected that you will have completed sufficient TB tests to take your Practical Assessment much sooner. Please see the Practical Training for ATTs page for more details.

Authorisation by the APHA

Once you have passed the online exam, you will be sent an email prompting you to nominate your AVS, and to download, complete and return your Sam declaration form. Once your AVS has accepted the supervising role and APHA have received your Sam declaration form, they will process your authorisation for conditional AHP status; a process which takes up to ten working days. You must not start work while you are waiting for authorisation. Once your authorisation is granted, you will be notified by an email from APHA and will be able to download your certificate of conditional authorisation from your Personal Training Dashboard.

Once authorised as a conditional ATT, you will work under the direct and continuous supervision of your AVS until you have fulfilled all the testing requirements and completed your Practical Assessment. Please contact Improve International in good time to ensure there are no delays in arranging this. APHA require a further five working days after you have passed your Practical Assessment to award you your full ATT authorisation. During this time you may continue to test in the presence of your AVS.

When you have been awarded your full ATT authorisation you may test alone but under the direction of your AVS. You will be able to download your authorisation certificate from your Personal Training Dashboard.

Please see the Practical Training for ATTs page for more details.
