S ummary . It is generally accepted that quantification of content validity is not possible. In this paper, a proposal is made by which a content validity coefficient, C cv can be calculated. An example of the use of the coefficient is given, demonstrating that different question combinations in a CSE biology examination in which a choice of questions was given gave different levels of content validity. The coefficient was used to demonstrate that deficiencies in validity in the examination are due more often to inadequate sampling of the educational objectives which the examination might be expected to test rather than to inadequate sampling of the subject matter.
