Reasonable adjustment refers to measures or actions taken to provide a candidates with a disability (or other limiting factor) the same educational opportunities as everyone else. To be reasonable, adjustments must be appropriate for that person, must not create undue hardship for the assessor and must be allowable within rules defined by the training package.

Reasonable adjustment activities could involve:

• modifying or providing equipment
• changing assessment procedures
• changing course delivery
• modifying premises.

The determination of 'reasonableness' requires judgement that must take into account the impact on the organisation and the need to maintain the integrity of the unit of competency.

This is defined a failure that conforms to a "fail safe" state. As such, this kind of failure cannot lead to an unsafe situation.

The opposite to right side failure is wrong side failure.

These are closely related to the principles of assessment and provide guidance to the applicant on the collection of evidence, and guidance to the assessor on the judgement of evidence. To ensure it is quality evidence, the requirements of valid, sufficient, current and authentic must be met.

• Valid means there is a clear relationship between the evidence supplied and the unit of competency.
• Sufficient means the performance criteria and evidence guide are addressed; competency over a period of time is demonstrated; all dimensions of competency are addressed; competency in different contexts is demonstrated.
• Current means that the evidence demonstrates the candidate’s current knowledge, skills and attitudes.
• Authentic means that it can be verified that the evidence is the candidate’s own work.
