Score Use and Interpretation of First Signed Language Assessments

This chapter provides a critical examination of the different uses of test scores; their interpretation by test administrators, educators, professionals, and researchers; and the implications these scores may have for test-takers. Before discussing the issues of test scores, an overview of the complexities involved in defining the L1 of deaf signers will be shared. Understanding the potential pitfalls of signed language assessment with a diverse background of L1 users is emphasized. Four sections address critical issues on scoring and interpreting assessments: purpose, consistency, norming and scoring, and interpreting the results beyond the score. Conducting valid and reliable language assessment is critical to establishing a baseline for intervention, education or research, monitoring an individual’s language competency and growth, justifying the need for additional language support, and providing accurate reporting to parents and administrators.
