摘要：This paper examines the uptake of Rasch measurement in Language Testing through a consideration of research published in Language Testing research journals in the period 1984 to 2009. Following the publication of the first papers on this topic, exploring the potential of the simple Rasch model for the analysis of dichotomous language test data, a debate ensued as to the assumptions of the theory, and the place of the model both within Item Response Theory (IRT) more generally and as appropriate for the analysis of language test data in particular. It seemed for some time that the reservations expressed about the use of the Rasch model might prevail. Gradually, however, the relevance of the analyses made possible by multi-faceted Rasch measurement to address validity issues within performance-based communicative language assessments overcame Language Testing researchers' initial resistance. The paper outlines three periods in the uptake of Rasch measurement in the field, and discusses the research which characterized each period.
