ABSTRACT
In the first chapter of this volume, we echoed Mislevy’s perspective that the backing for warrants in an interpretive argument for a test would become comprehensible by constructing a narrative that points to a plausible conclusion (Mislevy, 2004). As the previous chapters show, however, the data that help to construct the TOEFL® narrative are generated from a variety of diverse scenarios, and therefore they need to be woven into a single account of the TOEFL interpretive argument. The purpose of this chapter is to develop this single narrative, which is the validity argument for TOEFL score interpretation and use.
