Abstract

This paper uses a discussion of the role of Rasch model IRT in the validation of two sub-tests of the Occupational English Test to argue for the usefulness of IRT as a tool in the exploration of test constructs and also to consider the implications of the empirical analysis presented for the validity of communica tive language tests involving the skills of speaking and writing.
