This unit of competency describes the skills and knowledge to evaluate and select test methods and/or procedures that are relevant to the current and evolving scope of the laboratory’s operations. Selection of test methods and/or procedures may involve the appraisal of new and emerging technologies and may inform decision-making about possible extension of the laboratory’s scope. Alternatively, it may relate to existing both routine and non-routine testing requirements, ‘one-off’ tests, client’s special requirements or new tests required to satisfy new legislative, accreditation, licensing or regulatory requirements. Tests may be quantitative or qualitative.This unit applies to senior technical officers, technical specialists and laboratory supervisors working in all industry sectors. They are required to demonstrate wide ranging, highly specialised technical skills. They are expected to execute sound judgement in the selection of appropriate methodology under the broad guidance of scientists/medical staff/engineers. All operations must comply with relevant standards, appropriate procedures and/or workplace requirements.No licensing or certification requirements exist at the time of publication. However, regulations and/or external accreditation requirements for laboratory operations exist, so local requirements should be checked. Relevant legislation, industry standards and codes of practice within Australia must also be applied.
