The emphasis should be on the quality of the evidence, not the quantity. So what is quality evidence? According to the four 'rules of evidence' your evidence must be:
- valid: covers all the requirements of the unit of competency
- sufficient: enough evidence to demonstrate your competency
- current: reasonably recent, as a general guide less than two years old
- authentic: your own work
- relevant: relates to the qualification or units of competency you are seeking
In addition, quality evidence is:
- consistent: representative over a period of time rather than one instance
- reliable: comes from a credible and verifiable source.
- diverse: comes from different contexts, locations and times.
