Continuity and Innovation: Revising the Cambridge Proficiency in English Examination 1913-2002. This volume documents in some detail the most recent revision of the Certificate in Proficiency in English (CPE) which took place from 1991 to 2002. CPE is the oldest of the Cambridge suite of English as Foreign Language (EFL) examinations and was originally introduced in 1913. Since that time it has been regularly revised and updated to bring it into line with current thinking in language teaching, Applied Linguistics and language testing theory and practice.
