Weighting of assessment objectives as evidence of validity

Research by AQA on using the achieved weightings of A level and GCSE assessment objectives to measure the validity of a qualification.



The purposes of this study are:

  1. to explore the achieved weighting of assessment objectives as a facet of validity and to establish a method for investigating and reporting on it
  2. where problems with achieved weightings are identified, to consider the possible causes and solutions that may be fed back into the specification design and examination paper-writing processes
