Introduction Although task-based language teaching (TBLT) and its companion, task-based language assessment (TBLA), have gained in prominence in research and teaching, research projects have been limited due to small sample sizes and a paucity of sharable data. In addition, although comparisons of learner development over time provide critical information that can inform second language acquisition (SLA), such longitudinal data are scarce, both in general and in TBLA/T. Moreover, data in languages other than English are equally difficult to access. Thus, this resource development project focuses on oral proficiency assessment data and reports on the design and plans for implementing an internationally available, multilingual corpus of speaking test data. The potential for the corpus is reviewed in light of preliminary research that explored lexical complexity and lexical diversity that employed parts of the corpus as a resource in language assessment research. The project will eventually result in a multilingual, sharable database of student oral language samples pre and post study abroad (SA) on the same tasks in each language that will allow for a variety of projects including but not limited to longitudinal comparisons of proficiency gains, task analyses, and complexity, accuracy and fluency (CAF) analyses.
