Adapting CEF-descriptors for rating purposes: Validation by a combined rater training and scale revision approach

open access: closedAssessing Writing, 2012
We explore how a local rating scale can be based on the Common European Framework CEF-proficiency scales. As part of the scale validation (Alderson, 1991; Lumley, 2002), we examine which adaptations are needed to turn CEF-proficiency descriptors into a rating scale for a local context, and to establish a practicable method to revise the initial scale ...
