Argument-based validation frameworks have been used extensively to guide test development (Li, 2016). However, most validation work has been conducted as a one-time endeavor in the initial test development stage rather than as a continuous evaluation process after the test has been put in use (Cummins, 2010). This study fills in the gap by illustrating how an argument-based validation framework—the CAL validation framework—can be used to guide the refinement of the WIDA ACCESS 2.0 Writing Test, a high-stakes test designed to assess the academic English development of K–12 English Language Learners (ELLs) in the United States (Kenyon, 2018).
