Elements of Competency Performance Criteria              
Element: Identify the measured quantity and the uncertainty components
  • Specify an equation for the measurement
  • List uncertainty components that are associated with each input in the equation
       
Element: Determine the size of each uncertainty component
  • Calculate the standard deviations and standard deviation of the mean from the repeated measurement results
  • Use calibration reports, manufacturer’s specifications, quality control and validation data, and experimental data to collect other available information on the uncertainty components
  • Assign degrees of freedom to each uncertainty component
       
Element: Reduce each uncertainty component to a standard uncertainty
  • Allocate an appropriate distribution for each uncertainty component
  • Calculate the standard uncertainties
       
Element: Calculate an expanded uncertainty to the required confidence level
  • Calculate the sensitivity coefficient for each uncertainty component and multiply each standard uncertainty by its sensitivity coefficient and ensure they are all expressed in the unit of the output
  • Calculate a combined standard uncertainty
  • Determine an appropriate coverage factor based on the estimated effective degrees of freedom
  • Calculate the expanded uncertainty
       
Element: Report the expanded uncertainty
  • Report the measurement result and uncertainty to an appropriate number of significant figures
  • Report the confidence level and coverage factor
  • Determine the appropriateness of the size of the expanded uncertainty relative to the tolerance or required accuracy of the test
  • Determine the fitness for purpose of the expanded uncertainty relative to the use of the measurement result
       

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assignment, checklist) and due date here

(add new lines for each of the assessment tasks)


Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
