Common questions
How do you calculate audit compliance?+
Divide the number of compliant results by all assessed results, leaving out any not applicable, then multiply by 100. 18 out of 20 is 90%.
What is a red, amber, green (RAG) rating?+
A traffic-light score against targets. A common pattern is green at 95% or more, amber from 85% and red below that, but trusts set their own.
