The medical certificate a New South Wales worker needs for weekly payments, stating what work they can and cannot do.
A certificate of capacity is issued by the treating doctor and renewed as the injury progresses. It records the diagnosis, the hours and duties the worker can manage, and the treatment planned. Weekly payments depend on a current certificate, so a lapse can stop payments.
This definition is specific to New South Wales. The same term can work differently in another state, and the glossary marks each entry accordingly.
