Both norm referencing and criterion referencing are essential to any assessment. There is no point in knowing how well a person performs in an examination in comparison to others, if we have no idea about the standard of achievement of these others. If we find that every single candidate is successful in achieving a particular minimum mark we are more likely to question the adequacy of the examination than to celebrate universal success, and quite rightly so. Given this, why is the question of standards so controversial, both inside and outside the profession? This seminar exposes the misunderstandings that arise in this field.
