Discussion of Validation Issues in Signed and Spoken Assessments for Adult L2 Learners

The use of argument-based validity as a framework for discussion of validity issues in spoken and signed second language (L2) assessment reveals many areas of commonality. Common areas include the role of systematic test development practices in the validity argument, the complexity of rating issues, the need to define and assess a construct of functional communication of meaning, and the centrality of test use in the validity argument. Examining these areas of commonality in this chapter reveals the fundamental similarities in the basic validity issues faced in spoken and signed language assessment. This chapter is a joint discussion of key items related to validation issues related to signed and spoken language assessment that were discussed in Chapters 8.1 and 8.2.
