For the purposes of this programme, the different scores are:
(minimum risk): 10 years or more since the last bTB breakdown within the herd
9 to 1
The score corresponds to the number of years since the herd regained Officially TB Free (OTF) status after a breakdown.
(high risk): The herd is OTF at this point but has had a bTB breakdown within the past year.
(maximum risk): Not participating, or the animal is bought-in and cannot use the herd status.
To move up through the scores within the programme, herds must meet the requirements of the statutory scheme and be deemed to be adhering to CHeCS standards.
