Welcome to CamExam
Our Models

Through our research we have developed theoretical models

  1. of the psychological processing involved in answering an exam question; and
  2. of the types and qualities of mark schemes.

Recently we have integrated these into a more comprehensive model
  1. of how to construct valid exam tasks; and
  2. of how to design a valid exam.


We believe that validity must be built into assessment from the start. At every stage of designing, producing, and using an exam, mistakes can be made which will reduce the ultimate validity of the test results.

Much of our current activity is related to developing the third model as a way to ensure the validity of educational assessments.
