There are various other sources of information you can follow up once you've established what the basic performance criteria and parameters are for your assessment tool, as defined by the unit of competency.

We have already talked about the value of the SOP as a reference source, but here are some other suggestions if your assessment tool relates to an industrial process or machine.

• Company documents - such as work procedures, risk assessments, production sheets, maintenance logs and quality control forms.
  
  
• Industry documents - such as Australian Standards, codes of practice, manufacturer's operator manuals and industry guidelines.
  
  
• Company personnel - to find out about known problems or issues that the company has experienced in areas such as quality control, breakdowns, accidents, incidents or near misses.

In the end, your assessment tool needs to provide the assessor with a comprehensive set of checklists and benchmarks for measuring the candidate's ability to apply their skills and knowledge to the task that the competency describes. So the practical demonstration requirements and background knowledge questions should cover such aspects as quality standards, safe work procedures, performance benchmarks, laws and regulations and technical details relating to the job.
