Critical Evidence

There are four critical characteristics of evidence proposed:

Valid

This relates to the relevance of evidence. It must assess what it claims to assess and be relevant to the activity to which it is attributed and

demonstrate the performance of that activity.

Sufficient

This relates to the amount of evidence. There must be enough evidence to satisfy that the activity is in fact performed. If, for example, there is insufficient explicit documentary evidence, it may be necessary to refer to implicit sources of evidence, such as observations or interviews.

Current

This refers to the currency of the evidence. The reliability of the evidence is greater the more recent it is and therefore the more accurately it will reflect current processes, practices and behaviours.

Authentic

The evidence must relate to the performance and results of the specific service being assessed and not to another related service or to a wider organisation of which the service of which that being assessed is only a part.
