Employability Skills | |||
Learning Outcomes and Application | This unit of competency covers the ability to use statistical analysis to estimate and report measurement uncertainty in accordance with the ISO Guide to the Expression of Uncertainty in Measurement (or its replacement Standard). Personnel are required to review their estimates of measurement uncertainty to assist with making decisions on the fitness for purpose of the measurements.This unit of competency is applicable to laboratory personnel who work in calibration and testing facilities, process and interpret data and are required to determine uncertainties using standard methods. The rigour required in estimating uncertainty will depend on the required accuracy of the particular calibration, test or measurement. While no specific licensing or certification requirements apply to this unit at the time of publication, laboratory operations are governed by relevant legislation, regulations and/or external accreditation requirements. Local requirements should be checked. | ||
Duration and Setting | X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting. Judgement of competence must be based on holistic assessment of the evidence. Assessment methods must confirm consistency of performance over time, rather than a single assessment event. This unit of competency is to be assessed in the workplace or a simulated workplace environment. A simulated workplace environment must reflect realistic operational workplace conditions that cover all aspects of workplace performance, including the environment, task skills, task management skills, contingency management skills and job role environment skills. Foundation skills are integral to competent performance of the unit and should not be assessed separately. Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate. Knowledge evidence may be collected concurrently with performance evidence or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept in each case). This unit of competency may be assessed with: MSL904001 Perform standard calibrations MSL905001 Perform non-standard calibrations Holistic assessment methods include: review of data worksheets, calculations, spreadsheets, databases, statistical analysis, graphs and/or tables prepared by the candidate questions to assess understanding of relevant procedures, trends in data and sources of uncertainty review of reports and records prepared by the candidate feedback from supervisors and peers regarding the candidate's ability to estimate uncertainty in accordance with workplace procedures. Access is required to all instruments, equipment, materials, workplace documentation, procedures and specifications associated with this unit, including, but not limited to: data sets and records test methods and description of test set-up computer and relevant software or laboratory information system workplace procedures. Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator. The assessor must demonstrate both technical competency and currency. Technical competence can be demonstrated through: relevant VET or other qualification/Statement of Attainment AND/OR relevant workplace experience. Currency can be demonstrated through: performing the competency being assessed as part of current employment OR having consulted with a laboratory about performing the competency being assessed within the last twelve months. |
