Abstract
This study investigates how a collaborative, argument-based validation process can support the development of
valid, context-sensitive task-based language assessments (TBLAs) while simultaneously fostering teachers’ assessment literacy and
competency. Conducted within Quebec’s adult francization programs, the study involved francization teachers in the co-design,
piloting, and iterative refinement of 19 summative assessment tasks targeting real-world scenarios such as job interviews and
healthcare interactions. Guided by Kane, M. T. (2013). Validating
the interpretations and uses of test scores. Journal of Educational
Measurement, 50(1), 1–73. argument-based validation framework,
the process emphasized classroom-based inquiry, reflective practice, and local pedagogical relevance. Drawing on logbooks, focus
groups, and observation grids, the findings reveal how engaging with validation concepts — such as domain definition, scoring, and
generalization — enabled teachers to make principled decisions about task design and implementation. The collaborative model
promoted a reconceptualization of assessment as an integrated component of teaching, enhancing teachers’ confidence, agency, and
understanding of communicative competence. This study contributes to both the TBLA and teacher education literature by
demonstrating how structured, practice-embedded collaboration can serve as a powerful vehicle for professional learning and
sustainable assessment design.
