This thesis is concerned with examination comparability and the assumption that achieved grades in GCSE examinations have common currency across subjects. Technical treatments commonly used to investigate examination comparability are discussed along with the assumptions upon which they are based and their limitations. A variety of technical treatments, taking into account population sampling, tiering, coursework and cognitive skill demands, are used to investigate comparability for GCSE science results from Welsh and English examining groups. Examination comparability is shown to be undermined by fluctuations in relative 'difficulty' across time, different correlations between subjects, curriculum changes, and sub-group effects.
