A comparability study using a rank-ordering methodology at syllabus level between examination boards

As part of the on-going programme of work to ensure the equivalence of standards of similar qualifications across different awarding bodies, both national and international, a new methodology for comparison has been trialled. A rank-ordering method [1,2] has been used relatively effectively to compare standards across boards at component level within a syllabus, however no attempts have been made to conduct the comparison at syllabus level using similar methods. The aim of this study is to conduct a modified approach of the existing rank-ordering method and to compare the examination standards of a syllabus between two boards at syllabus level. Question papers, mark schemes, syllabus specifications and candidates’, scripts for all components for the same examination session were collected from both boards. These were then evaluated by external consultants and the resulting data were analysed using the multifacet Rasch modelling technique. The methodology of the study, the research outcome and feedback from examiners are described in this paper.
