| Due to deficiencies of the traditional models of standard setting, this study intends to suggest a new method for setting standards employing Rasch measurement. Precise and efficient methods for setting performance standards and linking tests to ability scales is a much-felt need in today's educational contexts. The introduction of the Common European Framework of Reference as a common paradigm for language teaching and assessment stressed the need for such methods. The suggested method combines the classic test-centered method of standard setting with the probabilistic properties of the Rasch model to set several cut points on the ability continuum. The Wright map which jointly depicts the difficulty location of items and the ability location of persons on a common scale is the cornerstone of this method. |
